Apprentice 3 Hardwire Photo Sensor

Apprentice 3 Hardwired Photo Sensor

Models: PSC, R

The Hardwire Photo Sensor monitors light levels and signals the lighting control panel's inputs. Each sensor has 10 adjustable set points for on or off control. Each sensor has a built-in filter to eliminate false triggering from lightning or other sudden light sources. The indoor and outdoor photocell heads convert the analog light levels to a digital form and are UV and weather resistant.
