Bellman Visit System Information
Function
General
The BE1410 Bellman Visit 868 Door Transmitter is a radio transmitter within the Bellman Visit 868 System for
indoor use, which recognises the sound emitted by a doorbell.
The door transmitter is activated by the built-in microphone, via electromagnetic fields or via a BE9199/BE9200
Bellman External Door Microphone (accessory). On delivery the Door Transmitter is set to standard detection,
which is suitable for most doorbells.
The BE1410 Bellman Visit 868 Door Transmitter is suitable for use with a doorbell which gives a clear tone without
any significant and rapid variations in sound. If the doorbell is electromechanical, the Door Transmitter also detects
the electromagnetic field emitted by the doorbell. It is important that the Doorbell emits a detectable sound so that
the door transmitter does not misinterpret it as speech, music, a vacuum cleaner or something else one does not
want the door transmitter to respond to.
If there are difficulties in getting the Door Transmitter to respond to the doorbell, a BE9199 or BE9200 Bellman
External Door Microphone can be used instead of the Door Transmitter's internal microphone.
If the current doorbell, door telephone or telephone sound is difficult to detect even with the External Door
Microphone, we recommend using a different solution. Other conceivable solutions are the BE1420 Bellman Visit
868 Pushbutton Transmitter or BE1430 Bellman Visit 868 Telephone Transmitter.
The Pushbutton Transmitter is a transmitter that can be placed on the outside of the door and this means that a
normal doorbell is not required.
The Telephone Transmitter is a multiway transmitter which can be connected electrically to an existing doorbell.
This cannot be done with all doorbells, door telephones or telephones.
Using the Bellman External Door Microphone BE9199/BE9200
If the BE9199/BE9200 Bellman External Door Microphone is used, the Bellman Visit 868 Door Transmitter can
detect the difference between the sound coming from the internal microphone and the external door microphone.
Using this function, the Door Transmitter can transmit different signals depending on which microphone the
sound is coming from. The External Door Microphone can, for example, be used for a doorbell with a sound that is
difficult for the internal microphone to detect, a door telephone or a telephone.
Please note: Do not place the Door Transmitter too close to the External Microphone since the internal microphone
may interfere with the External Microphone.
It is important for the doorbell, door telephone or telephone to emit a loud enough sound, so that other loud
sounds in the vicinity do not deceive the Door Transmitter into believing that it is the doorbell, door telephone
or telephone. The sensitivity of the External Door Microphone can be adjusted using the training function and
this allows adjustments to be made to the doorbell, door telephone or telephone. It is important to carry out this
adaptation to ensure that the Door Transmitter operates as well as possible.
Sound training
The BE 1410 Bellman Visit 868 Door Transmitter can be sound trained from a maximum of three different
sound sources. The advantages of this are mainly that the Door Transmitter will be able to give a different
indication according to which sound source activates it, but also that this function will help to ensure that the Door
Transmitter is only activated by the desired sound source.
The Bellman Visit 868 Door Transmitter has three training options, two for the internal microphone and one for
the external microphone.
The requirements for a Door Transmitter to detect a sound is that it sounds in the same way every time, that it is
long enough and that it does not vary too rapidly.
