When i switched to alarm.com ( 2GIG module), I am told the existing siren provided by the builder will not work 2GIG module.
The only siren i have right now is from 2GIG module, which is not very loud. Is there a way we can make the siren (hard wired, not z wave) compatible with 2GIG module?
The right one is the door bell. I am guessing the left one is the siren
Other way around. The left device, the one in the photo without the cover on it with the three screw terminals, is a doorbell chime.
The right one in your image is a siren. A wired piezo siren can be used but only lower current draw ones. Would need to pop open the siren to check the model number for electrical characteristics.
