Settings & Adjustments
8.1 Detection beam direction
The LC-151 detection beam direction is fixed. As a result, it is recommended to face the
intrusion area with the detector.
8.2 Sensitivity
Adjustment
The calibration of detector sensitivity is performed by a single sensitivity potentiometer and
a Microwave intensity jumper. Changing the PIR sensitivity and microwave intensity affects
immunity to environmental noises and allows the detector to operate without nuisance
alarms in noisier environments. The microwave intensity jumper is marked with "H" (high)
and "L" (low) settings. The sensitivity potentiometer is marked with "-" to "+". Position "-" is
the minimum sensitivity and position "+" is the maximum sensitivity. The PIR sensitivity and
microwave intensity must be adjusted according to environmental conditions as follows:
