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.

Installation

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.

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.

Operation

Once connected to the power supply, the LEDs for monitor 6741W (/BM) will flash: wait for them to turn o (approx. 40 seconds) before starting to use the device.

Building mode, Kit mode

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 self­ignition and control actuators.
