so my backup battery siren tweaked because of some water and the company that installed it will not replace it so for now i was wondering if i could hook up a regular siren with the wires that were used to run the back up battery siren since they are already there? the back up battery siren has 3 wires and the regular has 2. ij ust want to make sure i will not short circuit anything.
thanks

I think the battery back up has a ground, siren lead from alarm, and battery constant.

I know the regular siren has a ground, and siren lead.

Just match the grounds, and the siren leads together.. then trace the +12v line to the battery and disconnect it.
