turn off. and red LED flashes periodically, this means the detector is at
the best position and has entered normal monitoring state. The
commissioning is finished. As the Yellow Led and the green LED
illuminate continuously, that means the detector is failed to calibrate
automatically and can’t enter normal monitoring state. Power on the
detector again, go back to step a) to repeat the commissioning
procedures.
2) Fire Alarm Testing
As the detector has been in standby state for over 20 seconds, use
Alarm Zone of IR light filter close to the detector to block the receiver
and transmitter parts windows. In this case, the detector should give
fire alarm and the red Fire LED turn on in 30 seconds.
Note: As the detector is set to sensitivity 1 or 2, fire alarm
testing uses IR Light Filter-1. As the detector is set to
sensitivity 3 or 4, fire alarm testing uses IR Light Filter-2. The
protective film covering two sides of IR Light Filter should be
removed carefully when the filter is used for the first time.
3) Fault Testing
Use Fault Zone of IR light filter close to the detector to block the
receiver or transmitter parts windows. The yellow fault LED should
turn on, detector will report fault, and the yellow fault LED turns off
with removing the filter immediately.
The Alarm Zone and Fault Zone of IR Light Filter are shown in Fig
13.
