[9.1.5] Filter Replacement
The filters do not substantially affect smoke performance
even when up to 90% of the filter is clogged. Quarterly
visual inspection usually suffices to determine whether the
filters should be replaced because only a high percentage
of contamination affects performance. If further testing is
required, compare differential pressure readings with and
without the filters installed. If the difference exceeds 10%
replace the filters. In no case should the pressure differen-
tial fall below 0.0015 inches of water.
[9.2] Standby, Alarm, And Sensitivity Tests
[9.2.1] Standby And Trouble
Standby — If the system control panel is programmed,
look for the presence of the flashing LEDs through
the transparent housing cover. The LED will
flash with each communication.
Trouble — If the detector LEDs do not flash, then the de-
tector lacks power (check wiring, panel pro-
gramming, or power supply), the detector
board is missing (replace), or the unit is defec-
tive (return for repair).
Test — The trouble condition can be caused intention-
ally to verify correct operation of the system.
Remove the detector board to cause a trouble
condition locally and at the system control
panel.
