DoorKing 8080-057 Retro-Reflective Photocell Type B-1
Installation
Adjustment
This retro-reflective photocell (UL 325 Type B-1) complies with the 2018 UL 325 standards. It must be wired to the control box using the
photocell’s NORMALLY OPEN input so the control box can monitor the photocell. The photocell is powered by 24 VAC from the #3 circuit
board terminal if desired. The relay output is rated for 1 Amp @ 24 VDC and 1 Amp @ 120 VAC 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.
