TEST LED should also clear.
d) Press the SELECT ON/OFF button to
switch off the flashing cursor.
28. Place the Auxiliary Zone into the One-Man-
Test mode (using the SELECT cursor as for
zones 1 & 2). Activate each detector & call
point in turn and check that the panel responds
as in 24 above (except that the AUX ZONE
Fire LED operates instead of the ZONE 1 Fire
LED).
29. Return the Auxiliary Zone to normal operation.
30. Operate the panel mounted Manual Release
Point and check that the panel reacts as
follows:
a) The red Manual Release Active LED pulses
b) The red System Activated LED illuminates
steady
c) The EXTINGUISHING SOUNDER circuit
pulses
d) Actuator circuits 1 & 2 operate
e) The internal buzzer in the control panel
sounds
31. Activate the Pressure Switch input (if fitted)
and check that the panel reacts as follows:
a) The Silence Alarms LED pulses
b) The red Manual Release Active LED pulses
c) The red System Activated LED illuminates
steady
d) The Gas Released LED illuminates steady
e) The Gas Released Signal Active LED
illuminates steady
f) The Gas Released Signal Relay activates
g) The EXTINGUISHING SOUNDER circuit is
steady
h) Actuator circuits 1 & 2 remain activated
i) The internal buzzer in the control panel
sounds
32. Press the Silence Alarms button on the display
board and check that the control panel reacts
as follows:
a) The Extinguishing sounders silence.

the panel reacts as in 30 above. Restore the
Manual Release device to normal and press
the EXTINGUISHING SYSTEM RESET button
to reset the panel.
35. Repeat step 34 for all devices connected to the
Manual Release input.
The primary functions of the panel have now
been tested.
The Panel can now be configured for the specific
requirements of the site via the internal DIL
switches. Once configured, the panel functions
should be tested to ensure correct configuration.
For any optional circuits in use (i.e. GAS LOW,
ISOL. VALVE, GAS TRAPPED, HOLD, ABORT,
REMOTE CTRLS, AUTO/MANUAL, 1
st
, 2
nd
& 3
rd
Stage Shutdowns) these should also be checked for
open & short circuit faults, and for correct activation.
If Status Indicators are used then check that the
correct indications are shown on the status
indicators and any switches fitted operate correctly.
Once all Panel functions have been fully tested,
the panel should be set to the AUTOMATIC &
MANUAL mode and left on soak for 24 hours.
DO NOT CONNECT THE SOLENOID VALVES
DURING THIS PERIOD.
After the panel has been successfully soak-
tested, the SOLENOID VALVES may be
connected to the actuator circuits and the panel
can be locked and left in a fully operational
state. Do not arm the extinguishing system
without authorization from the Site’s designated
Responsible Person.
All authorised users must be given adequate
instruction/training on the operation of the
extinguishing system prior to hand-over.
