Features:

BRT-320 is a ceiling mount occupancy sensor switch which utilizes passive infrared (PIR) sensor

to detect the heat (in the form of infrared energy) from people moving within a space. It can

determine when a space is occupied and turns on or turns off the loads automatically. It has an

advanced micro controller unit and uses a proprietary signal processing technique to avoid false

triggers.

Instant on and adjustable delay off time from 2 minutes to 60 minutes;

Ambient light override. Automatically measures the ambient light level, and there is no

trigger on when it is above a light level which can be set by the user;

Easy installation onto the ceiling with or without a holder;

Good for 24V DC loads;
