5.5Photocell Wiring1) Monitored SERIES II (STB) photocells (P/N 38176R.S or OPAKPE.S) can be installed as shown inFig. 6. Wiring to these photocells can be connected to either terminal (they arenot polarity sensitive). ( Troubleshooting in Section 8).NOTE: Installer must enable ODC STB in calibration mode. See page 6.7.2) To Mount Photocells: (Kit includes detailed Instructions).• Determine location for mounting. They do not need to be directly adjacent tothe door but must be somewhere along the wall where there will be anunobstructed line between them. Fig 7.• Screws provided for mounting on soft material (wood, drywall, etc.)• They must extend out away from the wall sufficiently that no door hardwarebreaks the plane of the photo-beam.1) Nominal 24 Volt DC Commercial photocells with normally open contacts can beconnected as shown in Fig. 8.NOTE: Blue wire supplies 20 – 40VDC. Photocells used must be compatible with thisvoltage range.NOTE: If no voltage is present at Blue wire, check fuse F-1 on Control board.Series II Safe-T-Beam® Monitored PhotocellsCommercial Non-Monitored PhotocellsWARNING: Photocell systems provide entrapment protection whenmounted near the doorway in such a way that the lower portion of an individual’sleg will break the photocell beam during normal walking conditions.WARNING: Actuating operator using constant contact on the CLOSE button willoverride external reversing devices, including photocells.SERIES II (STB)RESIDENTIAL SAFE-T-BEAMS®CONTROL SIGNALTERMINAL STRIPODCSTBODCSTBFigure 6CONNECT WIRES TO EITHER TERMINAL.(NOT POLARITY SENSITIVE )Figure 7N-OREVERSE N-OREVERSE+-+-THRU-BEAMPHOTOCELLSCONTROL SIGNALTERMINAL STRIPRECEIVERTRANSMITTEREXT RADIO CONNECTORPWR20 40 VDC @ 315mAMAX CURRENTRELAYGNDNOM+ 24VDCRADIOBlueOrangeYe lowFigure 8www.geniecompany.com 08-12Counter Door OperatorGCL-GCX
