The POLOphone intercom system could not be simpler to install, using a two wire bus throughout. Connect entry panels and phones to any point on this bus and the system is up and running. Added to this, the system only requires a low current 12V DC power supply. It can be connected to the battery of a CENTURION gate motor for power failure protection.
From each handset, the gate motor, or door lock adjacent to the entry panel, can be operated. An auxiliary pushbutton is also provided for activating a secondary function such as the pedestrian-opening on the gate motor. In addition, the gate motor status feedback signal can be wired to the built-in indicator LED located in the cradle of each handset.
