Abstract
In wireless access control system, a method and system for minimizing power consumption at Wireless Access Point Modules WAPMs while maintain communication between said WAPMs and at least one Wireless Panel Interface Module (WPIM). When the WAPMs are not actively in use, the WAPMs minimize the power supplied to the wireless transceiver and enter a sleep state. While in the sleep state, the WAPMs periodically transmit a heartbeat signal to the WPIMs to confirm that the communication link between the WAPMs and the WPIMs is still valid. Additionally, an emergency beacon may be transmitted to the WAPMs to unlock the WAPMs to provide quick egress.
