I was searching on google and I found - Lifetone HL Bedside Fire Alarm and Clock. This device is a fire/smoke detector monitor that "listens" for any standard home smoke detector 3100 Hz, TS alert tone and then sounds its effective 520Hz square wave tone, and activates a pulsed bed shaker for maximum effectiveness in waking our lot in the scenario of a fire emergency. This monitoring allows the Lifetone to alert from any of the detectors in an interconnected smoke alarm system, thus giving extra time for safe evacuation, even when the fire has erupted far from the sleeping quarters - maybe the garage or kitchen. This device will be shipping the first week in APRIL 2009. BELOW is the direct website for more information.
