Hi, does anyone know how to wire a few backup sirens that do NOT use any wires, like the ground when armed wire from the alarm? The reason im asking is because I want some more hidden sirens but I want my security system to be more layered. I dont want someone to cut the power to my alarm (even though i have a backup) and the whole damn thing turns off. Is there a way so that I can turn on a toggle switch connected to relays, then if they try to power up the car (ignition) it turns on the relays and stays on even if the power is off? Meaning, can the power first go in the relays, then stay on until the switch is turned off? Any other ideas? Thanks

DEI 515R. Backup battery siren. Has a barrel key to shut down after the wires are cut.

 

YEs the backup battery sirens are great. Mount them somewhere hidden and drill out the front of the screws so they are impossible to get off.

 

You might want to be able to get to the key in case someone does cut the wires so you can turn it off. I try to hide it under a bracket where it won't be too hard to get to the key yet still too much work to remove the unit itself or damage it. Then, hide the regular sirens behind the bumper or under the battery, etc.
