1 General

The LC-151 is a unique motion detector utilizing a single (two elements) passive infra-red

element and Microwave technology for use outdoors in harsh environments.

The LC-151 is designed for outdoor use in the most severe and climatic conditions

and may also accommodate pets with the addition of optional pet immunity lenses.

High reliability is achieved by combining both dual tech hardware with highly sophisticated

software, greatly reducing the possibility of false alarms.

The active elements are comprised of a single (two elements) PIR and advanced Microwave

detector inside a stylish, rigid plastic body.

These special optics combined with a Microwave Doppler sensor assures elimination of “false

alarms” while maintaining high security standards for the detection of human intruders into the

protected area.

The detection sensitivity and range is controlled by a potentiometer allowing fine tuning, so that

the correct detection pattern will be set for every installation.

The LC-151 is designed to protect large areas and can easily be installed on walls in order to

provide a solid protection of the area while rejects interferences from birds and small animals due

to the optional “PET MASK” optics.

3 Assembly description

The LC-151 is a robust yet small detector which includes a large LED indicator that can be easily

observed from long distances to provide indication of intrusion. Using the supplied mounting

bracket, the LC-151 can be easily mounted to walls using the provided mounting screws. For

installations requiring the detection beam to be adjusted horizontally or vertically to obtain the

desired field of protection use the LC-B1-15X Outdoor Mounting Bracket pictured below. (not

included)
