Connecting Accessories
The ACCESSORY terminal block is the connection point for accessories such as keypads, push buttons, safety loops,
intercoms, etc. The ACCESSORY terminal marked GRN (green) is the common ground for all accessories. GRN is paired
with the terminals shown below when connecting accessories to the control board.
IMPORTANT: Make sure to twist the exposed wires tightly and insert them into the terminals without loose strands.
Tighten the set screws against the exposed end of the wires. A dab of household petroleum jelly in each terminal will help
prevent corrosion.
WHT (white) used with
GRN (green):
Functions with a normally open contact. This is the most frequently
used pairing for a doorbell button, keypad, or key switch.
First contact will start the gate.
Second contact will stop the gate.
Third contact will reverse the gate.
NOTE: The system will not work with a
lighted doorbell button!
BLU (blue) used with
GRN (green):
Functions with a normally open contact. This pairing is typically
used for free entry and free exit devices.
First contact will open the gate.
NOTE: If the gate is in the open position and begins to close, the
activation of the accessory device will reopen the gate. In
communities where the use of a emergency entry device is
mandatory, it should be connected to these terminals.
ORG (orange) used with
GRN (green):
Functions with a normally open contact. This pairing is frequently
used for safety loops.
This connection will not open your gate. The safety loop will
activate only while the gate is in use. When using this combination,
the gate will remain open or reopen if it is closing.
Make sure the control box power switch is OFF before connecting accessories.
