X-10 PowerHorn 110 Decibel Security Siren PH508/PSH01

Here's a remote siren that will scare anyone within a few room's distance. This powerful siren takes wireless X10 signals from the X10 alarm consoles. If the console's built-in siren is not loud enough, add this loud siren by simply plugging this unit into any 110V wall receptacle. Use multiple units so that the intruder doesn't know where the sound is coming from. A screw hole allows you to fasten the unit onto the receptacle so a burglar cannot yank it off. This unit is triggered by consecutive ALL LIGHTS ON AND ALL UNITS OFF X10 signals that are transmitted by the security console. This siren can be used with the X10 Powerflash Interface set to flashing mode. This siren is so piercing that it is hard to remain in the same room with it when it goes off.
