Operation
To open a gate enter any valid PIN Number on GAPLM. For multiple GCU’s, enter the PINNumber followed by the GCU Identity (1-4). For a remote control transmitter, press the corresponding button for 3 seconds (within 75' of GAPLM). On an Intercom, press the Remote button while talking to a visitor. At other times, hold the intercom’s Remote button for 10 seconds, to activate the Primary GCU.
NOTE: If the gate operator is not set to automatically close the gate, any of the above methods can be repeated to close the gate.

Gate Terminals
From left to right:
• Terminals 1 and 2: Optional 10-24 Vac power input.
• Terminals 1 and 3: Optional 9-24 Vdc power input. Ensure that the gate’s DC power supply “Ground” is wired to terminal 3.
• Terminals 4-8: Not used.
• Terminal 9: Relay Normally Open contact.
• Terminal 10: Relay Common.
• Terminal 11: Relay Normally Closed contact.
Relay connections typically wire to Open Gate input on gate operator. Up to 120 Vac Low current contacts. Max 1/2 Amp.

Troubleshooting
There is an error tone when the GCU is activated.
The GAPLM or DAILM is not communicating with the GCU. The GCU may be out of range. If the units work properly when close together, the GCU may need to be mounted higher off the ground or on a different surface. Metal, trees, or masonry cause the most interference. If the units do not work when close together, the GAPLM or DAILM has not been programmed to the GCU. Double-check the GCU’s Identity (1-4) and reprogram it.
Memory needs to be cleared.
Hold down the Learn button until the LED blinks a total of 8 times.

For most connections the default setting of 1/2 second is best. However, for connection to yard lights, cameras, etc. the device can be adjusted as to how long it stays on.
NOTE: For most gate system wiring, dipswitch #4 should be left “OFF”.
Open Gate Configuration
Use this configuration when using the Gate System as an open-only system, which automatically closes, based on timer or a magnetic loop. Enable the Auto-close feature on Gate Operator. Connect the GCU as shown in Wiring to Operator section. Refer to product-specific manual for wiring information. On the Intercom, disable Gate Status checking.
