NAC Fault LED if a fault is detected on an NAC

Power Trouble LED if an AC, battery or charger fault is detected

AC Power LED will turn off if AC fail or brownout occurs

Alarm Silence LED if Silence button is pressed after an alarm or trouble

Walktest LED if Walktest mode is entered

Zone Maintenance LED if a I3 smoke detector needs servicing

Earth Fault LED if a ground fault occurs (zero impedance to ground)

Battery Fault LED if low or no battery condition occurs

Charger Fault LED if a charger trouble occurs

4.4.6 Trouble Condition Restoral

The control panel performs the following upon restoral of all trouble conditions:

Turn off the FACP System Trouble LED

Turn off the FACP Zone Trouble LED

Turn off the remote annunciator Trouble LED and piezo sounder

Turn off the piezo sounder

Transfer the fail-safe Trouble relay

Turn off additional LEDs corresponding to specific troubles
