The FSP-3x1B sensors provide continuous dimming light level control based on motion and/or daylight contribution. They control 0-10 VDC LED drivers or dimming ballasts, as well as non-dimming ballasts and, with an FSP-Lx Lens, are rated for wet and cold locations. All control parameters are adjustable via the iOS or Android Sensor Configuration App capable of storing and transmitting sensor profiles. The FSP-3x1B family is available in three configurations for mounting inside a fixture, to the outside of a fixture via a 1/2” knockout, or to a pole.

Questions & Answers

I have FSP-311B-S and am using them outdoors. I need to configure the sensor so that the light is off during daylight. I reduced the photocell setting down to its lowest 1 FC and it still remains on.
