I have a simple siren
http://www.amazon.com/gp/produ…..#038;psc=1
I’m gonna hook it up the the relay port on the dvr to trigger remotely when needed, via the NO/COM hookups. Is it okay to use a 12v 1a single power supply? I’m not clear if a 1A is okay, or should it be less like 12v 500ma? Thanks.
Hello,
check out this link. It shows how we have connect a siren to our DVR.
Thank

Thanks for that but it doesn’t specify beyond a 12v multi adapter about the amperage. I just want to make sure that using a 12v 1A single adapter will not overload the relay in the dvr. I think it should be fine but I want to make sure.
