Abstract
Building monitoring and control systems including bi-directional radio frequency links between master and remote units wherein the remote units operate in a low power, non-receiving state a majority of the time is disclosed. The bi-directional capability allows coordinated scheduling which aids in allowing the remote units to transmit data only at periodic time intervals to extend battery life. The bi-directional capabilities also allow for re-read requests for alarm validation and for putting remote units in armed and disarmed states for power conservation.
