Colorado Marijuana Law known as “Amendment 64″

On December 10th 2012 Colorado approved Amendment 64 into their constitution. Article XVII; Section 16 was born so that the cultivation and retail sale of Marijuana was legal statewide. With all the new laws of course there will always be rules and regulations. The one I will be talking about in this article is section R 305. I will also be introducing the Bluetooth Access Control, the ECKey EK6 and EK7.

R-305 Security Alarm Systems and Lock Standards.

A – Security Alarm Systems Minimum Requirements.

One of the requirements when operating a Retail Marijuana Establishment is they must have a Security Alarm System that covers all perimeters, windows and entry points. They also need to have some sort of real time monitoring established. Well here at SecurityCameraKing.com we have access control hardware and software that allows you to monitor every entry point to your business.

WHAT IS ACCESS CONTROL?

Access_Control

R-305 A-3 States that a Licensee shall maintain up-to-date and current records and existing contracts on the licensed premises that describe the location and operation of each Security Alarm System, at SecurityCameraKing.com we have the most knowledgeable Sales Representatives on staff to sketch any scheme necessary when purchasing and installing our access control and locking systems.

Video example made by one of our Sales Representatives Dan Millard.

You can keep records of ALL incoming and outgoing traffic, from employees to customers. For personnel with special access you can grant them entry using the ECKEY EK6 (a blue tooth access control reader) configured to an existing alarm system or to one of our access control boards.

The other option if you don’t have an existing alarm system would be the ECKEY EK7 standalone bluetooth reader connected to an electronic door strike or maglock to grant access to employees or customers. This setup would also work great in an indoor or outdoor greenhouse cultivation environment. A benefit with the ECKEY EK7 is that you can use the Vizpin mobile app to control access to the unit.

There is also an EC Key app that is available for all iPhone and Android smartphones. The app allows your Smartphone to set access control and administrate your system the easy way.

Even if don’t own a smartphone, EC Key readers can work and pair with any discoverable Bluetooth device.

HOW THE ECKEY WORKS

EK6 uses a secure 128 bit Bluetooth encryption to convert your device’s ID to wiegand data and send back to your access control system. The EK6 proximity reader solves the hassle of having access cards, fobs, biometrics and keypads that all have to be touched by either typing in an access code, or touching your hand or finger on a scanner. With access cards you never really know who is actually gaining access to places they are not supposed to be in. The EK6 is hands-free using your smartphones Bluetooth technology to gain access through doors, garages, gates and any other place that you want to keep secure. The EK6, when triggered by a user’s Bluetooth signal, will generate a virtual card number and the device sends the Wiegand data to your access panel, and the panel will either see the card user as a valid user and open the door or an invalid user and not open the door.

softsoft2

Installation of the EK6 is simple. The Bluetooth reader can be integrated into any existing reader or access control system. Upgrading from keypads, cards, fobs, and biometrics is easy and affordable. I have been in the security business for many years and I will tell you this Bluetooth reader is brilliant. If I didn’t want certain employees in my office, supply closet, building, liquor room and places where money and inventory is kept, securing these places using hand-free devices like a smartphone would have been PRICELESS back in the day. Everyone knows that just like American Express, “no one leaves home without it” (meaning your cell phone).

Knowledge is Power! – Access Control and Circuits.

Written By:

Mechanical_relay_diode

As you may all know SecurityCameraKing.com serves The Surveillance Industry as well as the Access Control Industry. These two industries are different from one another and it can be overwhelming when installing or troubleshooting your system, mainly because transitioning from surveillance equipment to access control is not the same. Access control requires some knowledge of how circuits work. In this article, I will go over some basic circuit knowledge that will allow you to install or know what to do in a case where you will need to troubleshoot your system. This knowledge can come in handy especially in an emergency situation.

Lets start by going over open and closed circuits.

When a device has a label that reads “Normally Open” this means that in a normal state there is no electric current flowing through the circuit. Think of it as a momentary switch (ex. door bell) when the button is depressed it completes the circuit this allows the flow of electricity and the device will turn on a chime in the case of a door bell.

Lets see how a door bell circuit works.

20_27

The image on the top illustrates the circuit in an open state where there is no flow of electricity, the image on the bottom shows the circuit in a closed state where electricity will flow, allowing the coil on the electromagnet to become energized and with the assistance of a spring giving you the ringing sound.

Now that we know the differences between open and closed circuits I will go over how an access control panel functions and then we can move on to see how they should be connected and why it is very important to know these two basic circuit functions (Normally Open and Normally Closed).

An access control system is simply a controller that triggers ON or OFF circuits by means of relays. This means that any output from the relays can turn ON or OFF [Open or Close Circuits] devices such as a Mag Lock, which is a high powered Magnet that is normally rated in pounds. Closing the circuit in a MagLock will create an Electromagnetic bond that keeps the door closed until there is an input from a reader to the control panel. The control panel opens or closes the circuit using its relays. The diagram shown below illustrates how a Mag Lock functions in the “Control Panel”. In this case it is the “Switch” part.

image003

Lets see how a “Strike” circuit works. As you can see it works similar to the Mag Lock where the circuits closes and a coil will retract a rod that will allow the person to gain entry. This is called a solenoid.

Uavf2

Here is a Video on how this is accomplished.

Now that we have covered the basics, let’s move to some other details such as Fail Safe devices. These are devices that even when there is no power the device will continue to be in a locked position, keeping the door secure. Fail Safe devices are typically door strikes.

Electromagnetic Lock Types.

With Door Status Switch: This device will show an open or closed door status to the system, allowing you to know if there is a door that is malfunctioning or someone has propped the door with an object.

With Delay: This will give you a few seconds before the mag lock will release the door. This is most common in a high security area.

The use of Mag Locks or Door Strikes are the most popular ways to control the entry or exit of a building.

Lets see how a one door system with a stand alone controller looks like.

system_diagram1

This is the easiest way to get a small business with only one door up and running with their access control. In the picture above, we see a Door Lock [Door Strike] connected to the Stand-alone controller with door sensors, as well as an exit and Reader. The user identifies himself with the use of a Card or Keyfob at the reader which sends a signal to the controller. The controller goes in its database and sees that this user has access and then completes the circuit to the Door Strike allowing the person entry.

Seems simple?

Lets try it with a control board instead of a standalone. This is good for a medium size business. In this illustration you will see integration with other devices such as a surveillance system by using its alarm outputs. We can now use the cameras as another form of a motion sensor. We can also integrate the system with a fire alarm panel. There is a lot of possibilities, and it is all about knowing the limitations of each board and system.

system_diagram2

Lets move on to battery back up and the use of fuses and Diodes.

When it comes to any security system, one will have the needs to keep these systems running even when there is not power present in the building, either by a malfunction of the Electrical System or by tampering.

There are different capacities of inverters such as 200VA, 250VA, 350VA, 400VA, 450VA, 500VA, 625VA, 1200VA, etc. The capacity of the inverter should be chosen based on how much watt of appliances you power at a time.

For a UPS with 875Va we can use a maximum load of 640 watts. For a UPS with 677Va we can us a maximum load of 540 watts

The main thing we have to understand is that whatever may be the UPS wattage, the battery backup will not vary. The battery backup will only vary depending on the battery Ah and the Usage Load.

To calculate UPS backup, We have a simple formula.

UPS Backup = Battery Ah * (Volts/Load) * (1/Powerfactor)

For Example:

Lets calculate the back up for a system UPS

Load is the usage power. Suppose we are running a PC then the load is around 300 watts.
Power Factor varies for device to device, the average power factor is 1.4

Voltage is the voltage of the battery.
For a single battery the voltage is 12v.
If the batteries are connected in a series   Voltage = 12 * no. of batteries.

Battery Ah is the battery ampere used for the ups,

System UPS battery AH is 7

Then   Battery Backup

=  7 * (12/300) * (1/1.4)
=  7 * (0.04) * (0.7)
=   0.19 hours
=    19 Minutes

Note: You can use the same formula for calculating the battery backup for UPS or an INVERTER.

Battery back up systems can become complex if you are looking to power the devices for more than 30 minutes. Knowing how to calculate what you need is crucial when purchasing the correct back up system or building your own.

This also functions for a Solar Power system. In the case of a Solar Powered System you will have to take into account the Solar Cells as well as the location and knowing peak Sun hours. Here is an article that goes into detail in regards to solar power.

Diode_Diagram

Lets move on to the Function a Diode can have on an access control System. For this we need to know what a Diode’s function is. A diode is a small device with two terminals [+ side is called the Anode and the – side is called the cathode]. This device allows the flow of current only in one direction. This means that in a case where there is  malfunction and there is a device with a short, it will protect the device by not allowing current to flow back into the circuit.

Fun Fact: ;P

A Diode can be found on Light Emitting Diodes also known as LED’s. They work by electroluminescence. Try saying that 3 times, lol.  They work in the same principal where the + side [Anode] and the – side [cathode] and a Semiconductor crystal is in between these two. Depending on the semiconductor is the color that it will emit.

LED-labelled

Lets move on to Fuses.

Fuses are devices that have have a small strip of metal, usually encased inside a cylindrical glass with two ends that connect to a terminal.  They are widely used in the electrical industry as well as the electronic industry. These devices will allow current to flow, but when the amperage is high above its rating the small strip inside will melt, cutting electrical flow while preventing damage to the circuit.

The Fuse is represented by these symbols.

400px-Fuse-basic-symbols.svg

Now that you know about how the circuits work when it comes to Access control, you can safely install your equipment as well as make a wise decision as to what you need. Keep in mind that the conductors carrying the signals from one device to another is also important, as well as grounding properly each control board if utilizing more than one. Consult our Sales team for any questions that you may have and we can also assist you with Designing the perfect system for your needs.

How to Install Access Control Software Standard Server Version from IDTECK

Written By:
Wednesday, September 3rd, 2014

Access control is the ability to allow or restrict access to a place or to have the ability to deny or allow the use of a resource. The idea behind this is to control certain users and resources at a specific place so there is full control of how, when and where the resource is utilized.

Access control can be done manually or completely automatic, but how would you keep track of who, when, and how the resource was accessed? The short answer to that is Access Control Software.

Many access control devices are network capable, which means that they can be accessible over a web browser or through a software via TCP/IP. These devices can also have a Web Service Interface that can show you basic information such as logs, alarm events, etc. Most of these devices that have that capability are very limited on the things you can configure.

Every access control is different in the way they might require a specific set of settings to successfully connect with the main software. In this demonstration I will be showing you how to configure the Standard Version of IDTECK’s Access Control Software.

This software will require 2 sets of programs and setups. One is the server communication and the access control software itself. It is necessary to install SQL for the database of the software so it will be easy to export any database with settings later on. SQL Express comes with the Standard version for free so there is no need to acquire a greater version, unless there is a necessity to have advance settings on SQL. Other than that it should be straight forward.

NOTE: To make sure the installation runs smooth make sure that the following requirements are met:

1.- Windows 7 x32 or x64 bit
2.- At least 10GB of Space on your Hard Drive
3.- Make sure no other SQL Instance is running on your PC
4.- Minimum of 4GB of Ram and a Dual Core Processor with at least 2.00 Ghz.

Software installation

Download the Server version of the software from here: https://docs.google.com/uc?export=download&confirm=P8oW&id=0Bwe1rQdTv-n4YTNyQloteUtxZWM

Double click on the icon and proceed to install the software. Follow the prompt and install all of the necessary updates until you get to the section where you will need to named the Instance. See picture below

IDteck SQL Instance

After naming the instance of your SQL installation you have to make sure you remember the password because this will be required to configure the communication server. Click Next and the SQL process will begin by decompressing the files and preparing the installation process. When done, the following window will appear:

Customer Info

Type a name and a company name to continue the installation. Select all of the features on the list and click Next.

Database Selection

On this section make sure the database server is typed as shown in the picture above. Select SQL server authentication and use the following default username and password (sa) and (1234). Note: If you change the password then you will need to type that info under the password field. Click Next to begin the installation process:

SQL Finish Installation

Click Next to begin the installation. Check the following picture summary to make sure you have all of the SQL features that will be installed.

SQL Copying Files

When the installation is completed, the following 2 icons will appear on your desktop. These icons are essential to the software and a few more adjustments need to be made before we fire up the communication server.

Idteck Comunication and server

The next step is to make sure we have the software executed with administrative rights. To do this, right click on each icon and click on the compatibility tab, then select the “Run this program as an administrator”.

Run As

Double click on the IDTECK communication Server to begin configuring its settings:

Server Settings

After the software launches, click on server setup and the following settings will show as the picture above. Click on the Server IP and make sure that the IP is your computer name\IDTECK. The Database name will be STARWATCH_STD. Username is “sa” and password is “1234”. Authentication should be DB Authentication.

Note: if you change this (username and password) when installing the software then you will need to input the right information. Click OK when done and the result should be as show in the picture below:

Logview

Double click on IDTECK STANDARD Server Icon and input the username and password. The default username and password is admin.

Software login

After all this the software will open up and will display the following interface. From here we can prepare the software to communicate with the device you are trying to manage.

IDteck Software Interface

Note: This software is free with a limit of users and doors that can be run without a license. A pop-pop will show after the software is launched:

IDTECK Pop-up

 

Notice that because the software doesn’t have a device configured in it, the software will display certain errors. See picture below for reference.

No Comunication

To add a device go to “Device Setting Wizard” to configure the Default Site settings. Click the checkbox labeled “Whether to use” and click on the “Site Setting” button. A site settings box will display for you to type the communication server  IP address. The IP address will be the one your computer have. You can find out what IP address your PC have by going to command prompt and execute the ipconfig command.

Access Control Egress

Written By:
Tuesday, August 12th, 2014

firedoor2

The events that have happened in the news this past decade have ignited the security industry with many new devices to lock down your area of operation.  Since the expansion of security implementation across the planet there have been growing exponentially and confirmed concerns with access control usage such as people being trapped in burning buildings. Problems occur in the system design when implementing a system to secure the perimeter of a building and restrict egress from the building.  Access control methods such as using the employee badge or radio frequency key card (RFID) to enter and exit may not be appropriate in an emergency situation, especially since people have a tendency to panic.  Professional security access control companies can take steps to reduce or all together stop the negative impact that safety regulations require for egress of a building. Now let’s dive into how safety goals and access control security can be combined with exit points and alarm triggers.

Exit locations controlling access is the main concern from security professionals everywhere and creates strife between security and Fire safety regulators.  While it is allowed to lock your doors to prevent unwanted access to the building in fire code requirements, it is never allowed to inhibit egress from a building. National Fire Protection Association’s NFPA  Life states that every person within the building must be able to exit all doors in their path without use of tools, special knowledge, or effort for operation from the outside to open the door. In short, the path a person takes should be unobstructed to the exit and the door should be able to be open via a crash bar, lever, or very obvious huge button with large lettering that reads PUSH TO OPEN.

In most situations that address access control implementation dictates that door locks from the inside or egress side of door must open during events such as the activation of fire sprinklers or a fire alarm trigger. In most cases the door must remain unlocked until the alarms have been reset to a no-fault status.

The safety code does take into consideration that most false alarms come from smoke detectors. Since there is an understanding of the false triggers the code stipulates that the alarm can be triggered after more than 1 smoke detectors senses smoke there by triggering an alarm, or a combination of a smoke detector, heat detector, and pull station will trigger alarm. Systems for sprinklers and heat are more reliable, so the code requires evacuation when only one of these has its alarm triggered.

When companies want to have a system for access control to use card readers or other biometric access for tracking and restriction of movement in the building the company will have to have a way to address the fire code regulations for free egress in the event of an emergency. Specific hardware will have to be installed on the doors for exit. Panic hardware can come in different shapes and sizes. The main types of hardware are mechanical and electrical. Sometimes these can look like buttons label “PUSH TO EXIT”, or something like a crash bar which is just a bar to push to open the door. Mechanical actuation is from gears and hydraulics. Electronic actuation is with electric that opens or closes the lock. Such as the button to turn a mag lock on or off. Depending on the local municipality is if you will need one or both types of actuation. Most in not all areas are OK with using mechanical actuation as it does not fail in a power loss situation. The electronic actuation in many areas requires a back-up option to it such as mechanical or the door automatically becomes unlocked with no power.  Providing standardized panic hardware along the egress path normally used with access control is the best way to address the code’s egress regulations while still maintaining control at access points. The hardware will allow egress, however this can be used in conjunction with a security camera system to monitor usage in case of employees not following the badge out process policies. This would all be available for review at the Digital Video Recorder to determine if policies need to be changed or discipline action taken.

Types of panic hardware include electric and mechanical. The fixtures used will vary by location as different builders and floor plans will require. There is no one size fits all in this area. The most important standard to keep in mind is all equipment needs to be UL (Underwriter’s Laboratories) certified for use in a fire.

Certain businesses have circumstances in which they want to have personnel respond to the location before egress is allowed. This method of control can be critical to a company such as a retail outlet that does want to limit as much as possible the ability of thieves to perform a snatch and grab at their store by running out a unmonitored exit. The fire code allows for a delayed opening response from the door to prevent theft. The delay permitted is up to fifteen seconds without having to acquire a specific permit from your local fire marshal. After fifteen seconds you will have to prove need and get approval. You may request up to 30 seconds.  If you require a longer delay that will not be approved.  Also the code mandates that you will post clearly that the door does have a delay on it before opening to make the individual aware of it.

Implementing both security and safety in access control system design is not an easy task, and it does require advanced knowledge of the local codes in live setting in conjunction with access control. Prior planning is paramount for professional security experts to find inventive ways to work with the fire code to maintain control of the building for security. This will ensure a situation that will provide safety and security without code violations that turn into fines eating away at your bottom line.

Designing Access Control

Written By:
Friday, July 18th, 2014
access-control

Determining the necessary equipment for building access can be confusing and one must decide if Access Control is the correct way to go.  I will point out what benefits an access control system will give you.

  • Access Control will simplify the way you gain entry or access your Building.
  • No more handing out keys that later Employees or contractors might lose.
  • Credentials can be given that are either permanent or temporary. Any guests, contractors or Employees can utilize these.
  • Typically if a key is stolen or lost there comes the daunting task of re-keying the whole facility to conserve security. The cost for lock cores can be between $30 and $75 or greater and a locksmith will charge for labor about $50 an hour or more. This can get really expensive with a location with multiple doors, especially if the key that was stolen or lost gives access to many doors.
  • Audit Trail: Using normal keys will not keep a log of who has gained entry to the building or location. A surveillance system will help but the daunting task of going over footage to find who gained entry is time consuming.
  • With the use of Keys in many facilities you are required to lock each door and unlock at every start and end of a business day.

What areas should I Secure?

After deciding as to why you want an Access Control System, you will ask yourself as to what assets to secure. You want to cover doors that will be used frequently. Doors that are not used frequently do not require hardware for access control unless there is are high value assets. These doors include areas such as a closet, non-critical offices, and mechanical spaces just to name a few.

Areas that Access Control is typically applied to are:

Exterior Doors:

access_control

Typically exterior doors are the first to be secured. This greatly simplifies the access to your building and this also means that your staff does not require any keys, while also keeping unauthorized persons outside of all entrances except those who you specifically allow entry. Any type of Visitor will be directed to a certain area. Typically this is handled in different ways. The first is a remote scenario where the Visitors find themselves in front of an intercom in some occasions as well as in front of a camera where they can speak to a Manager or Security Staff who will then release the door and allow them entry into the facility.

In a scenario where the guests are greeted by staff usually the front door is left open or there is someone to open the door like a Door Person and then speak with someone at the Front Desk. Usually this person will give the guest a temporary ID that will double as a key to gain entry to key points of the facility.

 Gates:

adgate6

In most cases Gates are added to access control systems. This will create a perimeter from the front door. This is great for High security locations or in areas where there is higher crime rates. It is also paired with Surveillance equipment that will allow Security to view all areas of the Property as well as any entry points at the gates.

HR and Accounting Areas:

DHRfront

These areas are key locations that will have sensitive information that need to be secured at all times.

Data Closets / Server Rooms:

network server room

There is an increase need for network security, access control data centers and IDF’s [Intermediate Distribution Frame]. Consider the server room is often the brains of any organization. There are specialized systems that are manufactured for security cabinets in larger or often multi-user Data Centers.

Classrooms:

crxxi3-lg

With thefts of electronic equipment being more often in schools nowadays it is best to keep the classrooms locked. Having Electromagnetic Locks or Electronic Door Strikes to keep these secure provides a lock down capability Also in emergency situations these Doors and any door that provides exit to the outdoors will go from a locked position to an unlocked position to provide anyone the ability to exit the building without the need of interacting with the system.

Cabinets:

Cabinet-Lock-for-Acess-Control

There are specialized locks in the market that will allow these locks to be integrated into your access control system, this is done so the access control may be added to the cabinet instead of a door that does not need access control.

Key Control Cabinets:

KWI_6-mod-vert_angled-resized

Many organizations will still keep keys in cabinets such as for their fleet vehicles, and other keys for cabinets etc. Often these keys are in an area where a criminal can gain access to them. Having access control on these cabinets will add an extra measure of security as well as keep a log of who has accessed the cabinet.

Forms of authentication and how many do you require?

The goal of Access Control is allowing the entry of people. To accomplish this you are required to choose how they are going to prove that they have legitimate access to gain entry. There are forms such as “Multi-factor Authentication” which is very popular among security installers. You can have your system setup where dual or triple mode authentication is needed where the users need a pin number and a card or the card and a finger print. If the two do not pass, the entrance to the location is denied. This is best since it makes it harder for the unauthorized user to gain entry. This can be inconvenient to users that misplaced their card or forgot their pin code. This will make the entry to this person a hassle each time they come in until they get a new card or a new pin code. Because of this, having multiple factor authentication will increase the overall level of security of the facility. For example condos are usually single factor, Military Bases are triple etc..

What type of lock should be used?

There are many types of locks that can be utilized for access control, all having their own application.

  • Electric Strike:  This type will replace the doors mechanism with its own. The plate is installed and once the strike is energized it will allow entry.
  • Electromagnetic Lock: This type of lock utilizes magnetism. It is also know as “MAGS”, it consist of a coil wire around a metal core which will produce a strong magnetic field. The magnetic field will attract both plates together enough to keep the door closed. This can be measured in pounds. Security Camera King carries MAGS from 600lb to 1500lb.

What Proximity Reader should be used?

The Proximity Card Readers allow users to send a request to unlock the door and they come in a variety of options.

Keypad:

rfk101v-srk101v-series-vandal-resistant-led-touch-keypad-proximity-59799lar

This is a very simple form for access control. The operator need to input his or her pin code to gain entry.

Card Reader:

rf20v-sr20v-series-vandal-resistant-proximity-access-control-reader-59798lar

There are many types of cards with their own type of encryption. Currently in the industry there are two – contact and contact-less.

Bio-metrics:

fingerprint-access-control-proximity-high-compatibility-readeraccess-control-readers-59862lar

Typically there are many of these readers and the most used is the Finger Print reader. There are others such as Iris, Geometry of hand and of course retina.

Whichever technology you choose to utilize, Form factor should be taken into consideration. Remember when I spoke about 3 Factor and single factor. Depending on the application is the reader that you would need. There are for example 12 inch square reader that may be positioned at the parking garage or miniature or thinner readers on aluminum door frames. Generally speaking the distance at which the card can be read increases with the size of the reader and type of card.

How are the Readers Connected?

While the readers need to be located in entry and exit points they are required to send the data back to a panel or server which will handle the data and choose what to do with it. There are a few different ways to accomplish this. Some are TCP/IP while others require a serial connection. There are others that are wireless but they are not as efficient as a hard line.

Traditional Systems will use serial connections to link up the readers to the control panel. This is the most common but technology is changing and most boards will have their own Server built into them allowing the use of your existing network.

Do I need anything else at the doors?

When adding access control one thing to consider is your local safety codes. One that stands out is the use of push to exit or for example PIR that will notify the system someone is exiting. In the US, life safety code requires that there be a means to physically break power to the magnetic lock. In some facilities this is not used, as guests or personnel are required to utilize their Proxy cards or form of ID to exit the building .

What will Power my Devices?

Power supplies are a must when designing your Access Control System. There are different ways to tackle having a centralized power supply and this method is popular as it is easier to troubleshoot, but if the power supply goes bad the entire system does too. You can implement ways to have multiple panels for different sections to help with this scenario. There is also PoE (Power over Ethernet). A lot of devices nowadays are PoE compatible where only a Category 5 cable is needed to connect the device to the network and provide it with Power to operate.

Special Considerations?

In some occasions the use of access control is going to be different, here are some that you might run into:

Elevators:

IMG_20120111_100947

There are two ways to restrict access to elevators. Restricting the call button to a card. This method will call the car only when there is a valid card used. This method will utilize a single reader outside of the elevator. The second one is a reader inside of the elevator and this method will allow the user to certain floors. Once the user has presented their card or key FOB to the unit it will light the floors in which this person can access and the floors that are not will not be lit, preventing the user from going up or down to these. This requires an interface with the elevators travel cable and it also requires every floors input / output to activate and deactivate each of the buttons.

Harsh Environments:

PHG003-20635D-A5-RGB_2_03

When utilizing access control in harsh environments the devices need to be explosion proof. This means that the device will not create a spark that can create an explosion. While there are many cards that are specifically designed for these environments, they are typically a reader inside of an explosion proof enclosure, readily available from electrical distributors, and easily fabricated in the field.
