Abstract
A fire detection alarm system has a central controller (10) and three fire detectors (12a), (12b), (12c) located in parallel in a zone (14). An end of line device (16) is used to indicate the integrity of the zone electrical circuit through the fire detector (12a) to (12c). In order to determine which of the series of fire detectors is or is not functioning, LED's (24a) to (24c) are provided, which LED's (24a) to (24c) illuminate when the respective fire detector is receiving power. <IMAGE>
