The MSB series employs the latest passive infrared (PIR) technology to automatically control lighting for areas up to 1000 sq-ft, achieving energy savings and convenience. Each sensor employs a special 180 deg multi-segmented lens and PIR motion detector circuit to sense when a person enters the area and automatically activate the lights. The sensor will automatically switch the lights off after a preset delay if motion is no longer detected. The MSB Series fits in place of existing wall switches, connecting to existing wiring, similar to a typical wall switch. The MSB series is the simplest way to achieve energy saving lighting control with minimal installation time. To assure long relay life, the MSB series employs a low energy switch circuit to assure maximum contact life. These sensors are compatible with electronic and magnetic ballast loads.
