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 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.
Table 5: Front Panel Buttons
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.
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:
