Using this document

This quick reference manual provides all the information required for installing, assembling, and starting up a TwinBus

for intercom system. It does not replace the system manual. It provides a basic overview for the most frequent use of

door intercom and video systems in single or multi-family residential buildings. Only those devices specified in the

Contents are described. The system manual can be ordered free of charge via the Internet at www.ritto.de or from

+49 (0) 02773/812-0.

Please keep this Quick Reference Manual on hand for later use.

Information on article numbers

The article numbers of RITTO products are made up of three components. For example 1 7630/70

1 7630 / . . Device: TwinBus indoor telephone

/7 . Colour: white

/ . 0 Device index

This document only specifies information on the respective device. Please refer to the RITTO Manual for the colours

available and current device versions.

General Information

Cable networks

Existing lines can be used as bus lines. We recommend the following, commercially available telecommunication lines:

Telecommunication line J-Y (St) Y

Telecommunication line J-2Y (z) Y with strain-relief

Telecommunication grounding cable, longitudinally and transversally waterproof

Cable layout

It is recommended to lay the bus line from subscriber to subscriber and to connect it to the connection terminal on the

device.

All the line screening sheaths must be connected across the joints and laid to Terminal b on the TwinBus power sup-

ply unit. Please use appropriate locally provided terminals for this.

The stranded video line Va/Vb can generally be laid in the cable with the screened a/b lines.

In order to fulfil the general safety requirements for telecommunication systems complying to VDE 0800 and prevent

disturbances on the lines, ensure that the mains voltage and SELV (TwinBus line) are laid separately. A clearance of

10 cm must be maintained for the installation. In the case of a common line cabling, a separating webbing must be

inserted in the installation channels.

Bus lines a/b must not be terminated with terminal resistors.

Caution!

Malfunctions due to strong magnetic fields

No other devices with strong magnetic field (contactors, transformers, etc.) may be installed in the

direct vicinity of the power supply unit and additional devices. Malfunctions could be caused by

induced voltage peaks.

General Information

Maximum line lengths

The loop resistance of each TwinBus line must not exceed max. 20 Ohm. This results in the following maximum line

lengths:

Considerations when renovating

If commercially available doorbells are used, they must not have a contact transition resistance in excess of 10 Ohm.

Connection to the mains

Please note that a 230 V/AC power supply is required for the power supply units and mains transformers which are

not explicitly depicted in the block diagrams.

Electrostatic charging

Intended use

The RITTO door intercom is a system devised for controlling access and internal communication inside residential

buildings.

Any other use is considered unintended use. The manufacturer is not deemed liable for any damage resulting from

unintended use. The risk, in this case, is assumed solely by the installation technician.

Intended use also includes observing the manufacturer's regulations concerning use and maintenance. The system

may only be installed and serviced by persons familiar with it and informed of the risks involved.

Resistance in Ohm/m 0,0349 0,0621

Line lengths between TwinBus power supply unit 1 7573 and indoor telephone or

indoor video station 280m 160m

Line lengths between TwinBus power supply unit 1 7573 and door unit (lighting) 60 m 30 m

Line lengths between TwinBus power supply unit 1 7573 and door openers up to

8V/1A 50 m 30 m

Line lengths between power supply unit 1 4874 and indoor video station 100 m 60 m

Line lengths between mains transformer 1 6477 and indoor video station 50 m 35 m

Line lengths between mains transformer 1 6477 and camera module 35 m 25 m

Note:

In the case of existing YR cables, all the free wires on the TwinBus power supply unit must be laid

as screening to a Terminal b.

Caution!

Equipment damage through overvoltage or short circuiting

Equipment damage can occur through overvoltage or short circuiting. Connection must be made to

a 230 V~±10% mains power outlet. The power must be fed via an intrinsic line safety switch with

max.10 A.

Caution!

Risk of equipment damage through static electricity (ESD)

Static electricity could destroy equipment if direct contact is made with the printed circuit boards.

Discharge electrostatic charges before touching the equipment.

General Information

Video camera installation location

A camera can only view a certain area. In order for the visitor who has just rung to be monitored, for example, the

camera must be appropriately installed.

The surveillance area varies according to the angle the camera module is set.

The installation height is approx. 1.5 to 1.6 m.

Cleaning

The surfaces of the TwinBus devices can become dirty due to environmental influences and frequent use. The sur-

faces should only be cleaned with a damp cloth and suitable, mild household cleaning agent.

Stainless steel surfaces should be cleaned regularly with a commercially available stainless steel cleaning agent.

Make certain that the plastic parts of the door station (e.g. name labels) do not come into contact with the cleaner.

Observe the information provided by the cleaning agent manufacturer.

Directives/conformity

All RITTO TwinBus devices have been constructed according to the following directives:

EC Directive "Electromagnetic Compatibility" 89/336/EEC or 2004/108/EC

(complying with the currently valid version).

Directives on low-voltage 72/23/EEC (complying to the currently valid version).

RITTO TwinBus devices bear the CE approval label. Conformity has been certified. The corresponding documents

are held by the manufacturer.

Warranty

The general terms of business implemented by RITTO GmbH & Co. KG apply.

System bus

The power supply unit and additional devices are connected via the system bus. The system bus connector, enclosed

with each additional device, is used for this purpose.

The additional devices receive their power supply via the system bus. If the devices are installed on several mounting

rails, the 1 6907 bus connector is used instead of the system bus connector. Connection is made from the right-hand

system bus connection of the device to the left-hand system bus connection of the following device.

Note:

The area surveilled must be well illuminated, also at night. If necessary, appropriate lighting must

also be installed.

We recommend positioning an external light about 1 m above the camera. It should be an incan-

descent bulb of at least 40 W.

The camera must not be pointed towards the source of light (sun, lighting, reflection, etc.).

Caution!

Risk to life from electric shock.

In the case of surface installation of the power supply unit, the terminal cover must be attached on

the 230 V connection.

Caution!

Damage to the device through environmental influences.

The devices must not be mounted outside or in rooms exposed to damp.

Installation

Door intercom for single or multi-family residence

Each residential unit can be accessed separately from the main entrance. Thedoorbell for the apartment door is con-

nected directly to the indoor telephone. Incoming calls from the door station and the apartment door (ED) are auto-

matically indicated by different ringing tones. The door opener (TO) at the main entrance can be actuated from all the

indoor telephones.
