TECHNO TIP
All fire control panels have some outputs that must be monitored for open or short circuit fault. These outputs would
typically operate devices like bells, sirens, beacons, detonators, solenoids or relay contacts. All these installations
will require End-of-Line (EOL) devices and Zener diodes as shown below:
