Abstract

An intelligent thermostat communicates with threat detectors to allow periodic remote testing of the detector. The real-time clock and calendar functions of the thermostat allow the consumer to program the day, time, and frequency of the testing. The thermostat then communicates a test control signal to each of the detectors to initiate the self-test. The communication may be wired or wireless. During testing the thermostat displays a detector test screen. Upon completion of the self-test, the thermostat displays a test results screen for user confirmation. This results screen will indicate that the test passed or failed along with any diagnostic information provided by the detector. The thermostat also provides a test initiation screen from which the consumer may initiate a detector self-test manually. Loss of communications with a detector is also communicated to the user, as is the location of the detector that first identified a threat.
