when the jumper is in the “NORMAL” position.
3. If the jumper is in the “HARSH” position, the alarm will sound upon simultaneous and double
activation of both channels in a space of 12 seconds.
4. The detection range and the vertical angle of the device can be adjusted by sliding the PCB
up or down.
