Filters
Periodic cleaning or replacement of the filters will be required.
The filters are located inside the cabinet at the top of the unit (see
Figure 9 displayed earlier in the guide) and are removed as shown in
the sequence below:
Either replace the filter assembly or carefully brush off the accumulated
dust. (Replacement filter part number: FL-IF-6.)
Note:
If replacing the filter, remove the foam gasket from the old filter
and place onto the new filter. When placing the new filter into the slot,
ensure that the gasket is correctly aligned.
Refit the filter, close and secure the cabinet door. The unit will initialise
and restart.
Smoke Sensors
The smoke sensors are located under the sensor cover (see Figure
9 displayed earlier in the guide). To access the sensors, follow the
sequence below:

The
Default Password
is

.
If no button is pressed for 10s during the password sequence, the unit
returns to
Normal
mode.
Exit from
Maintenance
Mode
press the three front panel user interface buttons
TEST
,
RESET
and
DISABLE
simultaneously for 2 seconds.
Alternatively, reset the unit using the
Remote Input
(when set to
default value) or power the device off and on again.
If there is no activity in
Maintenance
mode for 5 minutes (default), the
FAULT
indicator blinks green for 15s and then the unit automatically
returns to the
Normal
state.
TESTING
Magnet Test
The alarm signalling can be tested for functionality by placing a test
magnet in the position shown in Figure 9 (displayed earlier in the
guide). This method does not reflect EN54 standards and does not
test the air flow in the pipe-work.
Smoke Testing
The system alarm response can be tested for functionality using
smoke. The choice of smoke source is dependant on the installation
but in all cases the smoke must be present for the duration of the test.
Smoke pellets or matches can be used close to the sampling point to
introduce smoke particulates into the system. It is recommended that
smoke with a particulate life cycle of greater than 120s should be used
– standard aerosol sprays for point detector testing do not work well
on aspirated systems
.
Fault Testing
Simulate a fault on the detector (for example, block the outlet pipe) and
check that a fault is signalled on both the front panel of the unit and at
the CIE (Fire Panel).
SERVICE
WARNING
Isolate the aspirating detector from the fire alarm system to prevent any
unwanted alarms when opening the front door of the unit. Make sure
all power is removed from the system before removing any covers.
Service Mode
Opening the cabinet door during normal operation will cause the unit
to enter
Service
Mode. The
FILTER
LEDs will blink, the unit will switch
off power to the fans and the fault relay will indicate a fault. When the
cabinet door is closed, the unit restarts automatically.
1) Press and hold
RESET
; Left flow indicator will turn
yellow, then green.
2) Release
RESET
and
FAULT
indicator will switch on
green. The left flow indicator will blink green indicating
the device is ready for the first digit.
3) Press
DISABLE
to increment the LEDs 1…9.
4) Press
TEST
to select a digit.
5) The flashing airflow segment will turn solid green and
the next segment will begin to flash indicating set the
next digit.
6) When the 4th digit is selected, all 4 airflow segments
are turned off. If the password is accepted the
FAULT
indicator will remain green and the unit enters
Maintenance
mode. If the password is incorrect the
FAULT
indicator flashes yellow and the unit remains in
Normal
mode.
