A method and apparatus to assist in testing of fire alarms and other emergency warning systems. Such a system typically contains annunciator devices (14) such as sounders, speakers or strobe lights and these must normally be checked for acceptable operation on a regular basis. The invention enables a single or married individual to activate the alarm system briefly, without creating undue disturbance for surrounding occupants of an office or apartment block for example. The individual can then inspect an event recorder (20) located near or integral with each annunciator, to check that the respective annunciator has operated correctly. Operation of the annunciator may be assessed by monitoring input or output of the annunciator, such as current levels, or audible or visible output. Alternatively, each annunciator may communicate an indication of acceptable operation directly to a main control panel (11). |
