Abstract
The invention provides a method for testing a hazard detector that includes transmitting a test mode switching signal from a test device to the hazard detector, setting the hazard detector to a test mode, transmitting a first test mode confirmation signal from the hazard detector to a central monitoring unit, transmitting a second test mode confirmation signal from the hazard detector to the test device, processing a hazard condition detected by the hazard detector as a test event, transmitting a test result signal from the hazard detector to the central monitoring unit, the hazard detector outputting a test completion signal, and setting the hazard detector to a detection mode. The invention further provides a hazard monitoring system, a hazard detector, and a test device.
