A: Try communication from another handset:

• Check the green status LED is illuminated on the speech unit at the gate.
• Check the handset has been powered on. Press and hold the power button on the handset or check for illumination from the buttons.
• Remove handset and wire to the gate station at the gate with 6 feet of cable and check if that works. It it does, then the cable may have a break or be the wrong type.

A: Swap them around, and check if the problem follows the handset or remains with the location. If it remains with the location, it is an installation problem. Check wiring, cable gauge used for power etc. If it follows the handset, call technical support. It may have a defect or be damaged. .

A: Listen for a relay click when the lock release button is pressed. Even better, remove the wires to the lock or gate, use a multimeter on continuity mode, and listen for bell tone when the lock release button is pressed. If that works, then it is an installation problem. Check wiring diagram for tips. If that does not work, check the distance from the gate to the handset. It may be too far to use the outdoor speech unit relay. Try using 2 cores to connect the relay inside the handset to the gate controller instead.
