There are 2 connectors on Gate Opener Unit, line in and latch connections. Unit does not require an additional power.

In order to open the gate, phone ring tone is heard after dialing unit's specific number and "UNLOCK" led turns on for 1

sec. Right after the gate is opened, busy tone must be heard, meaning that unit has made itself ready for the next calls.

'POWER' led indicates that system is connected and operational. You can control multiple barriers and doors on one PBX

system with each individual unit and different numbers.
