HAZARD DETECTOR, TEST DEVICE FOR HAZARD DETECTOR, HAZARD MONITORING SYSTEM AND METHOD FOR TESTING A HAZARD DETECTOR

摘要

The invention provides a method for testing a hazard detector comprising the steps: transmitting from a test device 11 a test mode switching signal to the hazard detector 13; setting the hazard detector 13 to a test mode; transmitting from the hazard detector 13 a first test mode confirmation signal to a central monitoring unit 1; transmitting from the hazard detector 13 a second test mode confirmation signal to the test device 11; processing a subsequent hazard condition detected by the detection means 5 of the hazard detector 13 as a test event; transmitting from the hazard detector 13 a test result signal to the central monitoring unit 1; outputting from the hazard detector 13 a test completion signal; and setting the hazard detector 13 to a detection mode. The invention further provides a corresponding hazard monitoring system, a hazard detector and a test device.
