8.5 Commissioning Procedure
NOTES:
In order to avoid accidental operation of the
solenoid valves during commissioning the
solenoid valves should remain disconnected
during the commissioning process. A suitable
load resistor (typically 47R, 20W, providing a
0.6A load, check manufacturer’s datasheet for
actual current or coil resistance) should be
connected in place of the solenoid to simulate
the presence of the solenoid coils. The solenoid
coils should be connected only at the end of the
commissioning process.
The commissioning engineer should also be
aware of any additional equipment connected to
the panel and the consequences of the
operation of that equipment during the
commissioning process.
Make sure that the ACCESS CONTROLS
Keyswitch is in the ON position before
operating any of the buttons on the display
board.
ALL internal DIL switches should be in the OFF
position at the start of the commissioning
process detailed below.
1. Turn ON the mains supply to the panel, and
observe that the control panel reacts as
follows:
a) The green Power Supply On LED
illuminates (display)
b) The yellow Manual Only LED illuminates
(display)
c) The yellow General Fault LED flashes
(display)
d) The yellow Power Supply Fault LED flashes
(display)
e) The yellow Batt/Charge Fault LED is
illuminated (control board)
f) The internal buzzer sounds (control board)
g) The Auxiliary Fault Relay operates
No other indications should be present at this
time, if there are, identify the fault and rectify it
by checking the following:
a) That no field wiring is connected.
b) That the EOL devices are connected
correctly in the panel terminals on each
monitored circuit.
2. Connect the batteries to the control board
observing correct polarity. Observe (after 20 to
30 seconds) that the control panel reacts as
follows:
a) The buzzer silences and the fault
indications extinguish.
b) The Power Supply On LED remains lit.
c) The System Automatic & Manual LED
remains lit.
Position the Thermistor in free air space
directly above the batteries. Use a cable tie to
secure the Thermistor to one of the battery
leads.
3. Press the Test button on the display board and
check that the control panel reacts as follows:
a) All LEDs on the display board and the
control board illuminate for 5 seconds.
b) The internal buzzer sounds for 5 seconds.
4. Switch off the mains AC supply to the control
panel and check that the control panel reacts
as follows:
a) The General fault LED on the display board
pulses
b) The Power Supply fault LED on the display
board pulses
c) The internal buzzer in the control board
sounds
d) The Fault Relay operates
e) The Mains Fault LED on the control board
illuminates
5. Restore the mains supply to the panel.
6. Remove the end of line device from the zone 1
terminals in the panel and connect the field
cabling. After a few seconds observe that the
panel returns to the quiescent condition.
7. For each detector on zone 1, remove the
detector from it‟s base and check that after a
few seconds:
a) The appropriate yellow Zone fault LED
pulses
b) The General fault LED pulses
c) The internal buzzer pulses
d) The fault output operates
Re-connect the detector and check that the
panel returns to quiescent.
8. Repeat step 6 and 7 on zone 2 and the
auxiliary zone.
9. Check that the zone detection circuits are
monitoring the wiring for short circuits correctly.
For each zone in turn, place a wire link across
the end of line device and check that after a
few seconds:
a) The appropriate yellow Zone fault LED
pulses
b) The General fault LED pulses
c) The internal buzzer pulses
d) The fault output operates
Remove the link and check that the panel
returns to quiescent.
10. Remove the end of line device from the Manual
Release Zone terminals in the panel and
connect the field cabling. After a few seconds
observe that the panel returns to the quiescent
condition.
11. Check that the Manual Release Zone circuit is
monitoring the wiring for open circuits correctly
