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.
