ABSTRACT:
A method of intermittently disabling the generation of an alarm signal by a plurality of interconnected adverse condition detectors during a temporary alarm locate period such that the adverse condition detector actually detecting the adverse condition can be identified. In an interconnected system of adverse condition detectors, all of the detectors generate an alarm signal when any of the detectors is sensing an adverse condition. When the test switch on any of the detectors not actually sensing the adverse condition is actuated, the alarm signal is inhibited on all of the detectors except the detector actually sensing the adverse condition. The alarm signal is inhibited for a majority of the alarm locate period and allowed to activate for only portions of the alarm locate period.
