The Visit Telephone Transmitter
Art. no. BE1430
Introduction
The Visit system consists of a number of radio transmitters and receivers. The transmitters detect different events in the surrounding area and transmit a radio signal to the receivers. The receivers pick up this signal and provide indications using light, sound and/or vibration. The transmitter determines what type of light, sound or vibration should be displayed so that the reason for the indication is evident. Read through the entire user manual first and then start to install the system. Getting started
Unpacking, installing and testing the unit
1. Open the Battery Cover (8). Connect the telephone flex to the telephone connector (6) and insert the adapter plug in the telephone socket. Fit one battery, either a 6LR61 alkaline or 6F22 lithium type battery, and close the battery cover. 2. Press the Test Button (2). The Telephone Transmitter lights up the LED (1) to indicate that the unit is transmitting a radio signal. The Visit receivers will indicate the Telephone Transmitter.

The Telephone Transmitter can be mounted on the wall either suspended on the wall mount bracket (9) on the screw supplied or using the self-adhesive Velcro tape. If the Velcro tape is used, the wall on which the transmitter is to be positioned can be cleaned using the enclosed wet wipe. The telephone transmitter can also be placed on a level surface, e.g. a table, but you should avoid placing it on the floor. Function
The Telephone Transmitter is a radio transmitter within the Visit System for indoor use, which recognises ring signals from an analogue telephone system via a plug, which is inserted into the telephone socket. In addition to using the telephone input, the telephone transmitter can also operate as a multifunction transmitter, either via a pushbutton or via 2 connectors for an external trigger. All inputs can be detected separately and transmit different signal patterns to the receivers in the Bellman Visit system depending on which has activated the telephone transmitter. There is a range of options for connecting the telephone transmitter to various applications. Radio key
On delivery all Bellman Visit units are tuned to the same Radio Key. If you have a neighbour with a similar system, you can change to different Radio Keys so that you do not affect each other’s systems. All units in a system must have the same Radio Key. If you use the Radio Key Switch (5) to change the Radio Key on this transmitter, you must also change all other units in your Bellman Visit System to the same Radio Key. Refer to the user manual for the relevant unit. Please note:
All Bellman Visit products within the same system must be tuned to the same Radio
Key in order to operate as a group.
Indicators and Signals
System indicators
When the LED (1) lights up, the Telephone Transmitter transmits radio signals. Power supply
When the Telephone Transmitter is activated, the LED (1) normally lights up green. This means that the battery is in good condition. If the LED (1) lights up yellow, this means that the battery is flat and must be changed. Only use a 6LR61 (alkaline) or 6F22 (lithium) type battery. Troubleshooting in brief
SOLUTION
Change the battery. Only use an alkaline Nothing happens when the transmitter
is activated with the test button.
Check that all the connections are correct. The LED (1) lights up yellow when the
Change the battery. Only use an alkaline 6LR61 or a lithium 6F22 type battery. Telephone Transmitter is activated.
Check that the receivers are not placed too far away by moving them closer to the The LED (1) lights up green when the
Telephone Transmitter is activated, but
the receivers are not signalling.
Check that the Telephone Transmitter is set to the correct Radio Key. For further information see Function/Radio key. Change the Radio Key on all units in the The receiver signals when no

Number of Radio Keys:
64 Radio Keys as standard. Special software can be used to increase these to 256 Radio Keys in increments of 64 per software purchase. Contact the nearest supplier for further information. Coverage:
The normal coverage between a transmitter and receiver in the Bellman Visit 868 System is approximately 200 metres with a clear line of sight. Coverage is reduced if walls and large objects screen off the signals. Any thick walls constructed of reinforced concrete will greatly affect coverage. The system may also be affected by radio transmitters such as TV transmitters, computers, mobile phones, etc. This means that a unit may work perfectly in one part of the room but not at all in another. Activation
Via test button. Via built-in microphone. Additional information
