While in a walk-test mode, a battery powered wireless sensor transmits a plurality of wireless communication signals each at a different transmit power level, and for each of the plurality of wireless communication signals, listens for a corresponding wireless acknowledgement signal. A security panel listens for the plurality of wireless communication signals transmitted by the battery powered wireless sensor, attenuates the plurality of wireless communication signals by a predetermined margin, and transmits a wireless acknowledgement signal to the battery powered wireless sensor for those attenuated wireless communication signals that are received and recognized by the security panel. The battery powered wireless sensor determines a minimum transmit power level based at least in part upon the wireless acknowledgement signals from the security panel.

System and method for adaptive power management in wireless sensor communication

Supervisory signals from a first wireless security sensor are received at a first supervisory rate that repeatedly confirms that the first wireless security sensor remains operatively coupled to a security system controller. A first security sensor alarm is received from the first wireless security sensor and in response, the first supervisory rate is changed to a second, higher, supervisory rate. Supervisory signals are received from the first wireless security sensor at the second supervisory rate that repeatedly confirms that the first wireless security sensor remains operatively coupled to the security system controller. When a second security sensor alarm is received from the first wireless security sensor within a predetermined period of time after the first security sensor alarm, an alarm condition detection alarm is issued from the security system controller.
