Photocell Wiring
NOTE: Installer must enable ODC STB in calibration mode. See page 6.9.
2) To Mount Photocells: (Kit includes detailed Instructions).
Determine location for mounting. They do not need to be directly adjacent to
the door but must be somewhere along the wall where there will be an
unobstructed line between them. Fig 9.
They must extend out away from the wall sufficiently that no door hardware
breaks the plane of the photo-beam.
1) Nominal 24 Volt DC Commercial photocells with normally open contacts can be
connected as shown in Fig. 8.
NOTE: Blue wire supplies 20 – 40VDC. Photocells used must be compatible with this
voltage range.
NOTE: If no voltage is present at Blue wire, check fuse F-1 on
Control board.
Series II Safe-T-Beam® Monitored Photocells
Commercial Non-Monitored Photocells
WARNING: Photocell systems provide entrapment protection when
mounted near the doorway in such a way that the lower portion of an individual’s
leg will break the photocell beam during normal walking conditions. If an
alternative location is chosen it must be approved by the facility owner.
WARNING: Actuating operator using constant contact on the CLOSE button will
override external reversing devices, including photocells.
