End of Line Units
End of line (EOL) units are critical components in fire alarm systems, used to monitor the integrity of fire detection circuits. Positioned at the far end of a detection loop, these units provide a fail-safe mechanism by detecting any open or short circuits in the wiring. When the circuit is intact, the EOL unit ensures that the system remains in full operation. If the circuit is broken or a fault occurs, the EOL unit triggers an alert, ensuring immediate attention and preventing undetected failures. EOL units help maintain system reliability and compliance with fire safety standards.
