by disconnecting the End-Of-Line resistor at
the end of the circuit and checking that after a
few seconds:
a) The yellow Manual Release Fault/Disabled
LED pulses
b) The General fault LED pulses
c) The internal FIELD MR FAULT LED
illuminates steady
d) The internal buzzer pulses
e) The fault output operates
Re-connect the EOL resistor and check that
the panel returns to quiescent.
12. Check that the Manual Release Zone circuit is
monitoring the wiring for short circuits correctly
by placing a wire link across the Manual
Release zone end of line device and checking
that after a few seconds:
a) The yellow Manual Release Fault/Disabled
LED pulses
b) The General fault LED pulses
c) The internal FIELD MR FAULT LED
illuminates steady
d) The internal buzzer pulses
e) The fault output operates
Remove the link and check that the panel
returns to quiescent.
13. Remove the end of line device from the Alarm
Circuit 1 terminals in the panel and connect the
field cabling. After a few seconds observe that
the panel returns to the quiescent condition.
14. Check that the alarm circuit is monitoring the
wiring for open circuits correctly. Remove the
EOL resistor from the last device on the circuit
and check that after a few seconds:
a) The Fire Sounder Fault LED for on the
Display pulses
b) The appropriate yellow alarm fault LED on
the control board illuminates
c) The General fault LED pulses
d) The internal buzzer pulses
e) The fault output operates
Replace the EOL resistor & check that the
panel returns to quiescent.
15. Check that the alarm circuits are monitoring
the wiring for short circuits correctly. Place a
wire link across the EOL resistor in the last
device on the circuit and check that after a few
seconds:
a) The Fire Sounder Fault LED on the Display
pulses
b) The appropriate yellow alarm fault LED on
the control board illuminates
c) The General fault LED pulses
d) The internal buzzer pulses
e) The fault output operates
Remove the link & check that the panel returns
to quiescent.
16. Repeat steps 13 to 15 for alarm circuit 2 and
the extinguishing alarm circuit.
17. Ensure that the Actuators are disconnected
from the circuit cabling and are replaced with a
suitable load as described above.
18. Remove the end of line device from the
Actuator Circuit 1 terminals in the panel and
connect the field cabling. After a few seconds
observe that the panel returns to the quiescent
condition.
19. Repeat open circuit & short circuit tests on
actuator circuit 1 and check that the control
panel reacts as follows:
a) The Circuit fault & General fault LEDs pulse
b) The appropriate Actuator Fault LED on the
control board illuminates
c) The internal buzzer pulses
d) The fault output operates
20. Repeat Steps 18 and 19 on Actuator circuit 2.
21. Any additional monitored circuits being used
should also be connected in turn and checked
for correct open/short circuit fault monitoring by
removing or short-circuiting the EOL resistor
on each circuit and checking that the correct
fault indication is given on the panel.
Fault indications should clear once the EOL
resistor is returned to normal.
22. Check that the MANUAL ONLY LED is
illuminated. If not, press the AUTO & MAN /
MANUAL ONLY button once so that the
MANUAL ONLY LED illuminates
23. Place zones 1 & 2 into the One-Man-Test
mode as follows:
a) Press the SELECT ON/OFF button. The
SELECT cursor should flash on the FIRE
SIGNAL fault LED.
b) Press the SCROLL button. The cursor
should move to the ZONE 1 fault LED.
c) Press the TEST button. The ZONE 1 &
ZONE 2 fault LEDs should illuminate steady
(with a cursor flash on ZONE 1 fault LED).
The TEST LED should also illuminate
steady.
d) Press the SELECT ON/OFF button to
switch off the flashing cursor, leaving the
ZONE 1 & ZONE 2 fault LEDs and the
TEST LED illuminated steady.
24. Activate the first detector on zone 1 and check
that the control panel reacts as follows:
a) The red ZONE 1 Fire LED illuminates
steady
b) Sounder circuits 1 & 2 operate
c) The internal buzzer in the control panel
sounds
After four seconds the panel should
automatically reset, resetting the detector and
energising the RESET relay for 10 seconds.
