quite strong, you can go straight to step d).
Note: Observe the detector’
s optical pathway carefully to ensure
that the received light signal is reflected by the reflector rather
than by obscurations like wall, ceiling, or pillar. If uncertain, verify
by covering the reflector with opaque objects. If the green LED
flashes, it means the light is from the reflector. If the green LED
constantly lights, then the light is not from the re flector. The
optical pathway should be adjusted again.

commission tool quickly and make sure there is no obscuration on
the optical pathway. About 5 seconds later, the detector begins to
adjust automatically. Yellow LED flashing means weak light, green
LED flashing means strong light. If red LED, yellow LED and green
LED flash alternately, this means the detector failed to adjust
automatically and cannot enter normal monitoring state. Please
open the detector ’
s top cover and do adjustment from step b). If
yellow LED and green LED illuminate no more, and red LED flashes
periodically, this means the detector is at the best position and has
entered normal monitoring state. The commission is finished.

Fire alarm test
After the detector has been in normal monitoring state for 20 seconds,
cover the receiving window and transmitting window with the IR Light
Filter (please use the part for fire alarm test), the detector should report
fire alarm in 30 seconds and red LED should turn on. Remove the filter
and clear the fire alarm from the FACP, the red LED should go out, and
the detector should resume normal standby state.
