[6.1.5] 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.
[6.2] Standby, Alarm, And Sensitivity Tests
[6.2.1] Standby And Trouble
Standby —
Look for the presence of the flashing green
LED through the transparent housing cover.
The LED should flash approximately every
10 seconds.
Trouble — If the Green LED does not flash, then the de-
tector lacks power (check wiring, panel, or
power supply), the detector board is missing
(replace), or the unit is defective (return for
replacement).
Test — The trouble condition can be caused in-
ten-tionally to verify correct operation of
the sys-tem. Remove the detector board
to cause a trouble condition locally and at
the system control panel.
[6.2.2] Alarm Tests
[6.2.2.1] M02-04-00 Magnet Test
1. Place the painted surface of the magnet onto the TEST
locator on the bottom of the housing (Figure 9).
2. The red alarm LEDs on the detector should latch on,
as should any accessories (i.e. RA400Z, RTS451). Verify
system control panel alarm status, and control panel
execution of all intended auxiliary functions (i.e. fan
shutdown, damper control, etc.).
3. The detector must be reset by the system control panel,
the local reset button, or the remote accessory.
