Password Sequence to Enter
Maintenance
Mode
Press and hold
RESET
; Left flow indicator will turn yellow, then
green.
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.
Press
DISABLE
to increment the LEDs 1…9; press
TEST
to select
a digit.
The flashing airflow segment will turn solid green and the next
segment will begin to flash indicating set the next digit. 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. The Default password in
3111
.
If no button is pressed for 10s during the password sequence, the
unit returns to
Normal
mode. If there is no activity in
Maintenance
mode for 5 minutes (default), the
FAULT
indicator blinks green for
15s and then the unit returns to the
Normal
state.
TESTING
Note that the sensor LEDs, which are under the control of the CIE
(Fire Panel), must be turned on to activate the front panel alarm
indicators.
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 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 stops communicating with the fire
panel (the smoke sensors continue to communicate with the panel).
When the cabinet door is closed, the unit restarts automatically.
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:
