DESCRIPTION AND OPERATION

The FSP-321 is a motion sensor that dims lighting from high to low

based on movement. This slim, low-profile sensor is designed for

installation inside the bottom of a light fixture body. The PIR lens

module connects to the FSP-321 through a 1.30" diameter hole in

the bottom of the fixture.
The sensors use passive infrared (PIR) sensing technology that

reacts to changes in infrared energy (moving body heat) within the

coverage area. Once the sensor stops detecting movement and

the time delay elapses lights will go from high to low mode and

eventually to an

OFF

position if it is desired. Sensors must directly

“see” motion of a person or moving object to detect them, so

careful consideration must be given to sensor luminaire placement

and lens selection. Avoid placing the sensor where obstructions

may block the sensor’s line of sight.
The FSP-321 operates at 100-347V Single Phase, as well as

208/230/480VAC phase-to-phase. No power pack is required. It is

designed to be installed in both indoor and outdoor environments.

NOTE:

When the FSP-321 is powered up the first time, it will use

factory default parameters to operate. If adjustments are

needed, the Sensor Configuration mobile app must be

used.
