Power Supply & Wiring - Centurion PoloPhone Installation Manual

POWER SUPPLY & WIRING
Power Supply
The Polophone system operates off a 14V DC supply. The system is designed so that power can be connected to
any one of the components in the system.
If the system is being installed with a gate operator that can provide at least a 12V DC 150mA supply, the entry
panel can be connected directly to this unit.
NB: If the 12V DC gate motor supply dips when motors starts up and the intercom is being used at the same
time, the speech quality might be affected.
Alternatively if battery power is not available at the entry panel, CENTURION offers a 14V DC supply (mains
adapter), (order ref: POLOP000V1) that plugs into a universal two pin 220V AC mains supply socket.
A DC jack is provided on the output of the adapter that plugs conveniently into the cradle of any one of the
handsets in the system.
Terminals are provided on the cradle electronic module to terminate a 14V DC supply should the supply being
used not have a jack compatible with the socket on the cradle.
Wiring Wiring
The two wire bus of the Polophone system is polarised. If incorrectly connected the unit will not operate, but it
will not be damaged.
The length of the bus is limited to a maximum of 150m.
NB: It might be necessary to double up on the thickness of the 2 wire bus depending on the distance
between the entry panel and handsets in the system, and to which component the power supply is
connected (handset or entry panel). Refer to page 5 for the cable thickness schedule.
