Extinguishing Status/Repeater Units (Optional)
If Extinguishing Status or Repeater Units are attached to the Extinguishing Control Unit, check
that their LED indicators mirror those of the Extinguishing Control Unit as the service tests under
“Extinguishing Control Unit” on page 5 are conducted.
In the case of Extinguishing Status units, with the actuator still disconnected, do the following
checks:
1.
Remove link L1 from the Extinguishing Display board of the Status Unit most remote from the
Extinguishing Control Unit. Check that the "FAULT" LED’s illuminate on both the Extinguishing
Status Unit and the Extinguishing Control Unit. Check that the Fire Control Panel indicates a
fault.
2.
Reinsert link L1 that was removed in the above step. Check that the "FAULT" LED’s go out on
both the Extinguishing Status Unit and the Extinguishing Control Unit. Accept and Reset the
fault on the Fire Control Panel.
3.
Repeat steps 1 and 2 above, but using links L2 and L3 instead of link L1.
4.
Activate one of the inputs mapped to activate the Extinguishing Control Unit (use a Ziton Z-
SDT2 to activate a smoke sensor if required).
5.
Check that the red Fire LED’s on the front fascia of the Extinguishing Status Units illuminate.
6.
Silence the Fire Bell output on the Extinguishing Control Unit by means of the "Silence"
pushbutton on the front fascia of the Extinguishing Status Unit. Check that the bell output
responds accordingly.
7.
Activate the second input mapped to activate the Extinguishing Control Unit (use a Ziton Z-
SDT2 to activate a smoke sensor if required).
8.
Check, after the delay time, that the "Extinguishant Discharged" LED on the front fascia of the
Extinguishing Status Unit is illuminated, while monitoring the time taken for this operation.
9.
Turn the "Lockoff" key switch on the front fascia of the Status Unit and check that the "Locked
off" LED’s on the Extinguishing Control, Status and Repeater Units illuminate. Check that the
Extinguishant Discharge Siren connected to the Extinguishing Control Unit silences.
10.
Accept and reset the Fire Control Panel by turning the Lockoff/Reset key on the Status Unit to
RESET. Check that the Lockoff LED’s go off on the Extinguishing Control, Status and Repeater
Units.
11.
Test the hold off operation by completing tests in steps 1, 2, 4, 5, 6 and 7 above. Wait 10
seconds and press the “More Time” button. Measure the time between the activation of the
“Extinguishant Discharged” LED’s and releasing the hold off button. The measured period,
which is the configured delay setup by VR1 (on the main board), should be the same as the
time noted in step 8. Confirm that this is the correct delay time required.
12.
Repeat steps 9 and 10 to reset the unit.
Extinguishing Control Door Monitor Board (Optional)
If a Door Monitor Board is fitted, make sure that it is installed according to the Extinguishing
Control Door Monitor Boards installation sheet, document number 501-0077ZE-1-01.
1.
Check that this function is working correctly by turning the AUTO/MANUAL key switch to Auto
and leaving the door open. The Extinguishing Control Unit buzzer should sound, and after
approximately thirty (30) seconds the ZP3/ZP5 Control Panel reports a fault.
2.
Close the Door Lock Monitoring Switch by locking the door. The buzzer should silence
automatically. Reset the ZP3/ZP5 Control Panel.
3.
Record the results of the maintenance check in the system log.
