Abstract

A method and apparatus for use in wireless alarm systems is provided which enable the simultaneous sounding of any or all alarm devices in the system upon sensing of an alarm condition by at least one of the alarm devices. The alarm devices are battery powered and include a reduced power transmitter which transmits an alarm signal, with an optional address corresponding to the initiating alarm device. The alarm signal is received by a central receiver in communication with a central control unit. The central control unit transmits a broadcast signal to any or all alarm devices in the system via the central transmitter. The broadcast signal optionally includes address information regarding the alarm devices to be activated. Reduced power receivers in the alarm devices receive the broadcast signal, determine if the address corresponds to its own and activates alarm notification and illumination systems accordingly. The illumination systems may be independent from the alarm devices and may provide guidance to those trapped during an emergency.
