Title:
METHOD FOR INITIATING A REMOTE HAZARDOUS CONDITION DETECTOR SELF TEST AND FOR TESTING THE INTERCONNECTION OF REMOTE HAZARDOUS CONDITION DETECTORS
Document Type and Number:
WIPO Patent Application WO2006044360
Kind Code:
A8
Abstract:
A method of testing the operational status of remotely distributed hazardous condition detectors is provided. The method utilizes the detector's self-test button to initiate a detector self-test. Once the self-test is complete, the detector's alarm is silenced and a remote self-test signal is sent to the interconnected remote hazardous condition detectors. The remote detectors, on receipt of this signal, will initiate a self-test of their own as if a user had depressed their test button. The user, with the local detector's alarm now silenced, is better able to hear the remotely interconnected detector's alarm. To verify that the remote self-test signal is received, thus verifying the operational integrity of the communications link, the remote detectors may sound an alarm pattern indicative of the receipt of the signal before initiating their self-test.
