centsys POLOphone Audio Intercom Systems Instruction Manual

The INTERCOM HANDSET is a very versatile intercom system designed for a multitude of applications ranging from a basic 1 to 1 kit to larger installations with up to five components in the system. A component is either an entry panel or a handset as detailed below.

Expandability
The INTERCOM HANDSET can be configured using combinations of up to five components as follows:

Up to two entry panels
Two groups of handsets with up to three handsets per group
The system can operate without an entry panel connected

Each call button rings one or both of the groups of handsets, depending on the mode set. Intercommunication is available between the two groups of handsets.

Wiring
The system uses a two wire bus to link all the components, making the wiring of the system particularly easy.

Powering the system
The INTERCOM HANDSET operates off a DC supply and can therefore be powered from either a 14V DC mains adaptor or directly from the battery supply of a 12V gate motor system. The power source can be connected to any component in the system.

Operation

When setting up the system the handsets can be split into two groups. Intercommunication can only occur between these groups.
When the call button(s) at an entry panel is pressed it will ring the handset(s) linked to the specific handset group.
The entry panel call buttons can be configured as:

One-Button entry panel:
- Top button (A) and bottom button (B) rings all handsets in the system
Two-Button entry panel:
Top button (A) rings group “A” handsets
Bottom button (B) rings group “B” handsets
The factory default is a two-button entry panel. In a system with two entry panels, a V2 entry panel will only work with a V3 entry panel that has been configured for two-button operation, not one-button operation. V3 entry panels are compatible in either one- or two- button mode.

In an installation with two entry panels the call tone will be different for each entry panel. There will be a simultaneous ring at the entry panel to confirm the ringing at the handset(s).

Clip the long tail end of the telephone cord into the jack provided at the bottom of the Cradle and similarly into the Handset. Replace the handpiece onto the cradle.

Wiring

Power Supply
The INTERCOM HANDSET 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.

If the 12V DC gate motor supply dips when the motor 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, we offer a 14V DC supply (mains adapter), that plugs into a universal two pin 220 to 240V 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.
If the bus voltage (between terminals ”1” and “2”) is lower than 8V DC, power needs to be applied at another unit in the system.

Wiring
The two wire bus of the INTERCOM HANDSET 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.

It might be necessary to double up on the thickness of the two 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 cable thickness schedule.

For SMART Opererators, wire “*” into any of the output terminals that is configured to Gate Status (IO4 is defaulted to “Gate Status”)1

Only one 12V DC Power Supply is typically needed to power the system.
Power can be connected to any component in the system.
Figure 31 shows the 12V Battery Supply of gate motor connected to the entry panel to power the system.
If power is being connected to the handset use either a mains adapter with a DC jack compatible with the socket provided or connect 12-14V DC to the terminals.
If the bus voltage (between terminals “A” and “B”) is lower than 8V DC, power needs to be applied at another unit on the system.
