Coverage
The FSP-321B is an IP66 rated motion sensor that dims lighting from high to low based
on movement.
Three configurations are available. The FSP-321B mounts inside the fixture and the PIR lens
connects to the FSP-321B through a 1.30" diameter hole in the bottom of the fixture. The
FSP-321B-S mounts to a fixture/enclosure with a 1/2" knock out, via a nipple on the back.
The FSP-321B-D has a drop mount nipple, for mounting on to a pole, or to a fixture.
The sensor uses 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-321B 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 indoor and outdoor environments.
NOTE: When the FSP-321B is powered up the first time, it the will use factory default parameters to operate. If adjustments are
needed, the FSIR-100 configuration tool must be used.
Several lenses are available for use with the FSP-321B. Lenses give coverage at mounting heights between 8' - 40' for applications
such as, offices, warehouses and outdoor use. Density and range of the coverage is determined by the type of lens and mounting
height. Lens modules are IP-66 rated when combined with an FSP-321B sensor mounted to an outdoor rated fixture. See the FSP-Lx
Coverage Guide for more information.
