The circuit shown above enables the flame detectors to interface with most type of fire alarm control
systems. The fire relay RL1 is used to switch the required alarm load ‘R’ to generate a fire alarm signal.
An end of line device ‘EOL’ mounted in the last detector provides the system with the ability to monitor the
detector fault relay RL2 and the integrity of the interconnecting cables.
