Abstract
Systems and methods of backup battery support for switches and access points in fire detection systems are provided. Methods can include identifying a communications time interval for a plurality of devices, detecting a power failure, identifying a start time for a next scheduled communications time interval for a respective one of the plurality of devices, placing a wireless access point in a low power mode, and, substantially immediately prior to the start time, removing the wireless access point from the low power mode.
