Description
Monitors 6741W and 6741W/BM are hands-free colour video internal units, for installation in 2-wire video entry phone systems
and compatible only with power supply units 1209, 1210, 4888C and 4888CU.
The monitor, used in conjunction with the COMELIT app, makes it possible to answer calls directly from your smartphone/
tablet, whether you are at home or away.
The 6741W/BM monitor includes a magnetic induction amplification system as standard. Backplate art. 6710 is not supplied,
and is available to purchase separately.

Before definitive installation of the monitors, make sure the device has good Wi-Fi signal reception; the distance
between the router and monitors, and the construction materials used in the walls are factors that can aect signal
quality.
The Wi-Fi signal is not strong enough to guarantee correct operation. A Wi-Fi repeater must be installed between
the router and monitor in order to boost the Wi-Fi signal received by the monitor.

20 m MAX - Use shielded cable for the connection and do not route the cables in the vicinity of heavy inductive loads or
power supply cables (230V/400V).
Where multiple door-entry phones or monitor backplates have the same user code, connect the CFP button on one only; all
the devices will ring simultaneously.

Power management
N.B.
A single 6741W monitor can be installed for each user code; this will also be the only main monitor.
Configuration
For correct configuration, set DIP 1 of S3 (on/o) as follows:
• BUILDING Mode: (S3) DIP 1= OFF
√BUILDING mode must be set in systems powered by 4888C / 4888CU, while for systems powered by 1210, set BUILDING
mode when the number of 6741W (/BM) monitors is greater than 10.
In this mode you can answer video entry phone calls at home and away from your smartphone/tablet.
• Kit Mode: (S3) DIP 1= ON
√KIT mode is permitted in systems powered by 1210 with 10 or fewer internal units, and in systems powered by 1209 with 4
or fewer 6741W (/BM) units.
In this mode you can answer video entry phone calls at home and away from your smartphone/tablet, but also implement self-
ignition and control actuators.
For correct power supply management, main monitor and secondary monitor DIP 7 of S2 should be set in accordance
with the table (see below) and in accordance with the type of system and its configuration:

General intercom: call from one internal unit to one or more internal units identified by the call address used by the external unit.
Selective intercom: call from an internal unit to one or more internal units identified by a dedicated address (see table B)which
is different from the call addressed used by the external unit.
General and selective intercoms CANNOT be used together on the same riser.
If the default settings (table “Basic configuration”) do not reflect requirements, the buttons can be programmed dierently by
carrying out the steps below.

2. Press and hold the Privacy and Lock-release buttons for 3 sec.
»The internal unit emits 1 tone
»The Privacy LED flashes
»The internal unit enters audio mode
At this point the 2 operators are in communication with each other.
Step 2: intercom call programming
Operator 1:
fPress the button you want to program to call operator 2 (e.g. 2).
»Wait for a few seconds, until you hear the programming confirmation tone.
