Abstract

A fire alarm system comprises a control panel 13 and a plurality of combined smoke detectors and sounders 10 connected to a wire extending from the control panel 13. Each detector 10 is arranged to change from a standby condition to an alarm condition when activated by smoke, however the control panel 13 is only arranged to trigger the sounders 10 when the activated detector 10 has changed from its standby condition to the alarm condition at least twice within a predetermined time period. In use, if the detector 10 was activated by smoke eg. from cooking, the smoke will diffuse quickly and the detector will not be activated again, and the sounders will not be triggered. However, if there is a real fire, the detector will be reactivated immediately and the sounders will be triggered. <IMAGE>
