Most of the time, crimes occur when there is no one to notice and the perpetrators have vanished by the time anyone finds out. Now, you can overcome this problem with the AUTO DIALER SECURITY and SAFETY ALARM. The Auto Dialer utilizes infrared technology to passively monitor motion in the area of your choice. When you arm the unit the detector begins monitoring the area for motion. If motion is detected, the unit emits a 105 decibel alarm and begins dialing any of up to five telephone numbers that you select. This unit can also be used as a chime to alert you of motion. For example, you could use it in a retail store and the chime would alert you when someone enters. The Auto Dialer is simple to install and configure. One nine volt battery is required (not included). Connect the included AC adapter and telephone line, then position the unit in the desired location. This unit offers the following features: -Motion Detection with Auto Dialer -Large 14 Digit Display with Time and Date -Security Code with Delay Entry Timing -Five Programmable Emergency Phone Numbers -Pause, Panic and Prog Keys -Low Battery Indicator -Only Supports Tone Dialing -Selectable Alarm/Door Chime -105 decibel Alarm -Adjustable sensor -Test Mode -AC Adaptor with Nine Volt Battery Backup
