Pro700 Installation and Programming Manual

Discontinued Pro700 Intercom System

We are sorry the Pro700 Intercom System is no longer manufactured, a small range of spares are available while stocks last.

If you have a station which needs repair we can still make repairs as long as we can get the parts.

Please visit our "Intercom Products Range" page to find an alternative.


Ring Communications are one of the telecoms industry’s leaders. This is no more evident than in the Pro700 Intercom System range of devices. Offering a level of variety that makes it perfect for use in a multitude of industries, the Pro700 is an intercom range that punches well above its weight”

Pro700 Installation and Programming Manual Description

Ring Communications are one of the telecoms industry’s leaders. This is no more evident than in the Pro700 Intercom System range of devices. Offering a level of variety that makes it perfect for use in a multitude of industries, the Pro700 is an intercom range that punches well above its weight.

The Pro700 Intercom System range is packed with lots of the features that you would expect to find in the higher-end intercom systems of other manufacturers. This is ideal if your business needs room for growth. Whilst optimum benefits are to be attained at around the 20-station installation level.

The Pro700 Intercom System is an excellent choice if you are looking to keep your business costs down. Simple wiring combines with no central exchange to maximise cost efficacy. The Pro700 places quality and value at a premium whatever your usage environment:

The vast amount of choice that is provided within the Pro700 range is formidable, offering what essentially equates to a range of different devices, all within one range that offers total integration. Within the Pro700 range there are 6 different master systems to choose from, combined with 5 different variations of substation. Add this to further equipment and interface unit options and you’ve got the ability to create an intercom solution that’s totally tailored to your own unique requirements.

There are innumerable reasons why the Pro700 range represents a top option. Just a few of the main ones include hands-free duplex communication, hands-free speech, group calls, emergency all-call and music distribution.

*The Pro700 is a hardwired Intercom. All stations are interconnected with twisted 2-pair cable (CAT5/6 cable is a good choice as it is used by many installers for data cabling). The Pro700 can be wired in a star, loop or serial configuration.


General Installation Information


  • Up to 20 stations can be connected in one system.
  • A maximum of 16-20 stations is recommended.

Station connection

  • Desk-top master station AA711 is connected to wall sockets via station cords and RJ45 connector.
    • Various types are available
  • All other stations are connected with screw terminals inside the station.

Power supply

The power supply output voltage must be between 12 and 27 VDC.

  • All stations are connected to the power unit via the installation cabling.
  • The power current capacity depends on the system size.
    • LA617 18VDC/1A units should be used in systems with max. 5 stations.
    • LA618 18VDC/4A units should be used in systems with max. 20 stations. The output is adjustable between 13,5 and 18V
    • LA925 27VDC/5A units should be used in systems with long cable runs and max. 25 stations.
  • Maximum distance on a 0,6 mmØ /24 AWG wire between any station and a power unit is:
    • 12 V 100 meters (300 ft.)
    • 18 V 300 meters (1000 ft.)
    • 24 V 500 meters (1600 ft.)
  • A system can be powered with more than one unit to give a decentralized solution for large installations.

Battery backup

12 or 24 Volt batteries can be used as emergency backup power.

  • Adjust the power supply to act as a trickle charger
    • 12 V battery LA618 to 13,5 V
    • 24 V battery LA925 to 27,2 V

Installation cable

  • 2 pairs 0.5 or 0.6 mmØ (24 AWG) twisted telephone cable should be used for call and power.
    • One extra pair is required when Program Distribution (music) is required.
  • If the cable has to pass close to radio aerials or other interference sources, each individual pair in the entire installation cable must be screened.
  • A cable of good quality and low capacitance should be used.

Maximum cable length

The total cable run in a system is limited by a mutual cable capacitance of max. 87 nF.

  • Standard quality cable: 120 nF/km max. length: 700m (2100 ft)
  • High quality cable: 47 nF/km max. length: 1700m (5100 ft)

Cable layout

All stations are normally connected to the system power supply in parallel. Clusters of stations may have their own local supplies.

As all stations are connected in parallel, the system cable layout may be star- bus- or loop connected, or any combination.

Star configuration

  • The stations are cabled directly to the power unit which is used as a central distribution point.

Bus configuration

  • The stations are connected in parallel along one cable run.
  • The system power should be connected to a central point of the cable.

Loop configuration

  • The stations are connected in parallel along one cable run.
  • The system power should be connected where the majority of stations are located.


Power supply

  • The power supply must be wall mounted and located in an area with adequate ventilation.
  • The temperature must be between 0 – 35oC (32 – 95oF)
  • The relative humidity range of 30% to 90 % must be maintained.


  • Do not install power units or stations in an area near electrical  noise sources, including equipment such as heavy motors, welders, dimmers, radio transmitters etc.
  • Do not run the installation cable parallel to, or near power cables supplying voltage to such equipment.

If the cable passes such equipment the entire installation cable must be screened (each individual pair).

Note that screened cable has a much higher capacitance which will reduce the max. total cable mass
