Note
Disabling the Extinguisher output also disables the inputs and the outputs of
the extinguishing group members, except the Manual Release PB. When the
Extinguishing group is disabled, pressing the Manual Release PB triggers an
alarm, but not extinguishing.
15.12 Fault
The ECD monitors most of its inputs and outputs for faults.
When a fault is detected, the following occurs:
Fault relay and dialer are activated
Flashing fault LEDs: general fault LED, zone fault LED (if applicable), Ext, Zone LED (if
applicable).
i
Note
If a fault occurs in the extinguishing zone, the front panel extinguishing zone
fault LED flashes, and the LED of the specific extinguishing zone I/O, located
in the EM1 expansion module, next to the TB of the specific port, also
flashes.
Also, the specific fault LED in the front panel general area middle or left column is ON.
The buzzer sounds the Fault signal (1-4 ON-OFF time ratio.)
Fix faults when they are discovered.
15.12.1
Fault Relay Output
A dedicated Fault relay is provided.
The dedicated fault relay has SPDT contacts.
The contacts used for fault indication are the Common (C) and the Normally Open (NO)
contacts
During normal operation (no fault) the relay is powered and the Common and Normally
Open contacts are closed. (The Common and Normally Closed contacts are open)
During fault, or when the ECD is not powered, the relay receives NO POWER, the
Common and the Normally Open contacts are OFF. (The C and NC contacts are
closed).
15.12.2
FWRE (Fault Dialer) Output
This output is used as a FWRE (Fault Warning Routing Equipment, or Fault Dialer)
output as specified in EN 54-2.
i
Note
During normal operation, the FWRE output is powered. When a fault occurs
in the ECD, the power to the FWRE port is OFF, triggering the dialer.
