XTSH10A
The X10 Plug-In Powerhorn Siren Module, 105dB emits a piercing alarm when triggered by an X10 security system. The module plugs into a standard power outlet, and responds to continuous X10 On/Off commands. About 4 seconds after the commands stop, the module is silenced and automatically resets itself.
In addition to serving as an alarm, the Powerhorn Siren Module also works as an audio alert for received commands. When connected to an X10 alarm panel, the module can respond to "BRIGHTEN/DIM" commands. The BRIGHTEN command triggers a high-pitched chirp, while the DIM command triggers a low-pitched chirp.
