Sec-3.7Section 3: WiringExternal AccessoriesInterlock Switches, Sectional DoorsIf a slide lock is required on the door for pass through doors or other requirements, an interlock will berequired to prevent the opener from running when engaged. Install a Normally Closed interlock switch andwire directly to the operator. Remove the jumper between the EXT-INTK terminals on the control board andinstall wiring to these terminals.Photocells, MonitoredSee ENTRAPMENT page 1.5 for a list of approved monitored photoelectric devices. See instructions includedwith the photocell kit for detailed installation and programming instructions.Wire directly to the control board at the ODC-STB terminals.NOTE: The ODC-STB must be programmed to ON on the control board. See programming section in this manualfor details.Photocells, Non-MonitoredNon-Monitored reversing device must be Normally Open relay type. See instructions included with thephotocell kit for detailed installation and programming instructions.Wire directly to the control board at the N.O-SAFE terminals.NOTE: The use of Non-Monitored photoelectric devices will NOT provide Monitored Entrapment Protection. Use ofNon-Monitored devices only will require the user to maintain constant contact to close.Sensing Edges, MonitoredSee ENTRAPMENT page 1.5 for a list of approved monitored safety edge devices. See instructions includedwith the sensing edge for detailed installation and programming instructions.Wire directly to the control board at the ODC-STB terminals.NOTE: The ODC-STB must be programmed to ON on the control board. See programming section in this manualfor details.NOTE: Monitored Sensing Edges can be used with the Timer Control Module (TCM) or External Sensing Module(ESM). See ACCESSORY MODULE section below.Sensing Edges, Non-MonitoredNon-Monitored reversing device must be Normally Open relay type. See instructions included with thesensing edge for detailed installation and programming instructions.Wire directly to the control board at the N.O-SAFE terminals.NOTE: The use of Non-Monitored edge sensing devices will NOT provide Monitored Entrapment Protection. Use ofNon-Monitored devices only will require the user to maintain constant contact to close.Sensing Edges, WirelessSee ENTRAPMENT page 1.5 for a list of approved monitored safety edge devices. See instructions includedwith the sensing edge for detailed installation and programming instructions.Wire directly to the control board at the ODC-STB terminals.NOTE: The ODC-STB must be programmed to ON on the control board. See programming section in this manualfor details.NOTE: Monitored Sensing Edges can be used with the Timer Control Module (TCM) or External Sensing Module(ESM).
