PIR Motion Sensors & Switches

Passive Infrared SenSwitch LC-772


LC-772 is an innovative, standalone energy saving auto-switch designed for commercial/residential automatic lighting control.

It can be used to switch the light or other loads on and off by sensing the motion of people. Adjustable LUX and TIME allow user to set the switching control timing according to the ambient light level and light-on delay time.

IR-TEC's patented 2-wire power supply technology enables this auto-switch to retrofit the existing single control light switch.
