8.1.10 Zone Status (Fault Diagnostics)
To aid in diagnosing the type of fault on an evacuation zone, four buttons have been included on the
Master Control Panel of the ECP. These buttons represent the four types of evacuation zone faults
that can occur.
These faults are:
1.
Amplifier/speaker line faults.
2.
EAID faults.
3.
Visual line faults.
4.
