2.6 Wiring Relay Alarm Contacts

The fail-safe relay alarm contacts are labeled as 8 and 10 as the figure shown below. With a Normally

Close circuit formed by wiring with an external power and an alarm device (a buzzer or a flashing LED),

system will detect the power failure event. If a failure event occurs, the relay inside EKI-4524I will act as

an open switch, and therefore break the external circuit. The fail-safe design is intended for triggering the

connected alarm device for warning purposes.
