Warning
• Install the equipment by carefully following the instructions given by the manufacturer and in compliance with the standards in force. Do not tamper with the internal
elements offering protection against short circuits and overcurrents.
• All the equipment must only be used for the purpose it was designed for.
Comelit Group S.p.A.
declines any responsibility for improper use of the apparatus, for any
alterations made by others for any reason or for the use of non-original accessories or materials.
• All the products comply with the requirements of Directive 2006/95/EC (which replaces Directive 73/23/EEC and subsequent amendments), as certified by the
CE
mark
they carry.
• Do not route the riser wires in proximity to power supply cables (230/400V).
• Do not insert objects or pour liquids into the device.
• Installation, mounting and assistance procedures for electrical devices must only be performed by specialised electricians.
• Cut off the power supply before carrying out any maintenance work.
• Do not press and hold the audio hook while the handset is lifted.
• The camera must not be installed opposite bright light sources, or in places where the filmed subject is against the light. To resolve the above problem, we recommend
modifying the installation height of the camera, which is usually 160 - 165 cm, to a height of 180 cm and pointing the lens downward so as to improve filming quality.
• Cameras with colour CCD sensor have poorer sensitivity in low light conditions than black/white cameras. We therefore recommend, in dimly lit environments, to
install an additional light source
• IMPORTANT: to prevent a malfunction of the device, make sure that the metal fascia of art. 4893 does not rub against any other metal parts and damage their
insulation.

PROGRAMMING OF DOOR-ENTRY PHONE ART. 2638
INSTALLATION OF DOOR-ENTRY PHONE ART. 2638
The maximum total distance between the external unit and the furthest
monitor is 200 m (with cable Art. 4577).
The total number of internal units with the same user code and call
repetition devices (additional ringtone) connected to these internal
units cannot exceed 4 (with a maximum of 1 main internal unit and 3
secondary internal units). Connect only one call repetition device for
each internal unit.
The maximum cable length between the internal unit and call repetition
device is 20 m. A shielded cable should be used for the connection
and should not run close to heavy inductive loads or power supply
cables (230 V / 400 V).
POWER SUPPLY UNIT ART. 1209
For instructions on the installation and configuration of internal
units (Art. 6701W, 6700W, 6701W/BM, 6700W/BM) and the exter-
