Flush-mounted presence detectors are PIR sensors for recessed ceiling mounting. The load is automatically activated when motion is detected and the ambient brightness is below the set Lux value.
Detecting no movement and after waiting for the pre-set delay time, the load will be automatically shut down. The user can pre-set the brightness and monitoring time values through the potentiometers or the IR system for the control of automatic switching on and off with a low initial cost and great energy savings.
