Description
This retro-reflective photocell (UL 325 Type B-1) works with ALL DoorKing gate operators to comply with the 2018 UL 325 standards. It must be wired to the gate operator using the photocell's NORMALLY OPEN input so the gate operator can monitor the photocell. The photocell is powered by 12-24 VAC OR VDC from the gate operator if desired. The relay output is rated for 1 Amp @ 24 VAC OR VDC maximum. It MUST be mounted vertically as shown and not horizontally to protect it from the weather. The green LED will remain lit when the reflector is aligned correctly with the photocell. The photocell has a max sensing range of 35 ft.
