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 Detection beam range setting

The detection range may be set by tilting the detector while installed using the LC-B1-15X
Outdoor Mounting Bracket. The range may vary between 5 and 15m (16ft to 49ft).

8.3 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:
