extinguisher has been triggered, and it is now depleted (i.e. in a Fault condition), and
needs attention and corrective action, i.e. replenishment or replacement. The buzzer
remains in the Alarm mode (ON).
14.6
Reset Performed After Extinguishing Pulse Ends
If Reset is performed after the extinguishing pulse ends, then if alarm sources and other
non extinguishing related faults are removed, ALL alarm and extinguishing indications,
outputs and relays are OFF.
The Extinguishing Fault state remains:
The General Fault Led, the Extinguishing Zone fault LED the Fault Dialer and the Fault
Relay are ON, and the buzzer changes to the Fault state (1/4).
14.7
Reestablishing the Quiescent condition after
Extinguishing
After ALL the issues are resolved (Alarms removed and faults fixed) and the
Extinguisher is replenished and brought to working order, and Reset was performed, the
ECD remains in the Extinguishing Fault state, and needs be set to the Quiescent (Idle)
state.
To do this, using the ECD keyboard, the programming mode has to be entered and
exited, and then Reset has to be performed again.
If all issues are resolved, and there are no pending events, after entering and exiting the
programming mode, the ECD returns to the quiescent state. (See Operating Instructions
below).
14.8
Fault State
A fault in the system is indicated by flashing the yellow General Fault LED, and by
flashing the specific LED of the faulty device/Input/output.
14.8.1 Actions Performed During Fault
When receiving a fault event at the Control and Indicating Equipment (CIE), the Control
and Indicating Equipment (CIE) will perform the following operations
•
Flashes the general fault LED
•
Flashes the specific fault LED
•
Activating the internal buzzer in the Control and Indicating Equipment (CIE)
•
Activating the fault relay
14.8.2 Acknowledge / Buzzer-Off Operation
When an event causes LEDs to flash, pressing the "Acknowledge/Buzzer Off" key
causes the Password LED to flash quickly. This informs the user that a password is
required. Keying in the operator's password cause the following;
•
Silencing the internal buzzer
•
Switch ON the flashing LEDs.
14.9
Disablement State
Sometimes there is a need to disable some inputs or outputs of the system.
The Control and Indicating Equipment (CIE) will ignore alarms from disabled zones and
will not activate disabled outputs or relays.
When one of the zones or output is disabled, the "Disabled" LED is turned on to indicate
this status.
