Warm-Up Time
The detector will need to warm
up for the first 90 seconds after
applying power.
Pulse Counter
The pulse counter determines
the amount of beams that need
to be crossed before the
detector will generate an alarm. To set the pulse
counter, refer to table B.3.
Adaptive Pulse Count
Using the Adaptive pulse count feature, the
detector chooses between 1 or 2 pulses based on
its analysis of the received signal.
Vertical Adjustment
To position the PCB, turn the Easy Lock counter-
clockwise and slide the PCB up or down to the
required setting using the vertical adjustment
scale. The detector’s coverage area is 12m x 12m
when the PCB is positioned at 0. Slide the PCB up
towards the -8 position to decrease the coverage
area bringing the beams closer to the mounting
wall.
