wireless sensors and alarm panels - which play well together?

elinpedersenMarch 13, 2008

I am about to buy a wireless security system (e.g. the GE Simon), to be monitored by NextAlarm or alarm.com.

I wonder if any of the wireless sensors I already have (left by the prev. owner) can be reused in a new system I buy, like 5 wireless 58xx Ademco components (4 doors and 1 PIR). There is also a Homesight wireless door/window senso, HMSM4140. Can anyone tell me how I figure out what might be compatible with what.

Isn't there one or a few standard protocols that is being used? I have tried to look up transmission protocols but basically been unsuccessful - perhaps I look in the wrong places? There must be a simple way of checking the specs to determine if the sensor signal can be picked up by the control panel - without having to first buy the panel and do trial and error ;-)

Thank you for reporting this comment. Undo

If you want to reuse your existing wireless sensors, make sure your alarm panel is made by the same manufacturer. If you have existng Ademco sensors, you must use an Ademco panel with a wireless receiver such as the Ademco 5881. Nextalarm will support any number of different panels that use the 'contact ID' signalling standard. Don't feel you must use one of the panels that Nextalarm sells. I use a Ademco Vista 20P and have it monitored by Nextalarm. Those wireless sensors aren't cheap. You will probably want to try to reuse them.
