Smoke Alarm Transmitter

The Visit Smoke Alarm Transmitter
Art. no. BE1530/BE1550


Further information


The Bellman Visit Smoke Alarm does not require any connections. 


No adjustments are required for normal use. The relevant descriptions are provided below, if you wish to change a setting for some reason.

Radio key

In order to use several Visit Systems close to one another without interference, different Radio Keys can be set on the different systems. All Visit System units are supplied from the factory tuned to the same Radio Key, channel 0. This means that all Radio Key Switches on the transmitters are set to the OFF position.

  • To alter the Radio Key, move the Radio Key Switches (5) to the desired positions. Note that switch (6) is not a Radio Key Switch. 
  • The broadcast switch (6) has the function of switching on and off an additional safety function which makes the smoke alarm transmit to all receivers within its range regardless of the Radio Key that is set.

Please note:red triangle

All Bellman Visit products within a system must be tuned to the same Radio Key in order to operate as a group. If the broadcast switch (6) is in the ON position, however, all Visit receivers are activated when a fire alarm signal is detected regardless of the Radio Key. If an incorrect Radio Key is set on the Smoke Alarm, neither the battery warning nor the Test Button will work with Visit System’s receivers. This function ensures that, when in Broadcast mode, you will not interfere with other Visit Systems when you test the smoke alarm or have a low battery.

Signal pattern

A Signal Pattern is the name for the way in which a receiver in the Visit System indicates activation. Changing the transmitters’ Signal Switch changes the Signal Pattern which the receivers display when the transmitter is activated.

Type LED pattern Sound Vibration Flash
Fire alarm Red bliks constantly Fire alarm constant Long Yes
Fire alarm flat battery Red blinks every five seconds Fire alarm one short One short Yes



It is easy to test the Smoke Alarm. If the unit does not work as described below, you can check further under Troubleshooting/Troubleshooting guide.

How to test

Test the Smoke Alarm at least once per month and preferably each week, e.g. during cleaning. Always test it immediately after any holidays or other extended periods of absence. 
A receiver in the Visit System which is set to the same Radio Key as the Smoke Alarm is required to test the Smoke Alarm with the Test Button (2) or by blowing in smoke. Proceed as follows:

  1. Press the Test Button (2) until the Visit Smoke Alarm starts to beep with a shrill tone and then release the Test Button immediately.
  2. The Visit receivers will then indicate a flat battery.
  3. Hold down the Test Button (2) for at least 5 seconds or blow smoke into the Smoke Alarm. The Visit Smoke Alarm will transmit a radio signal after about five to ten seconds.
  4. The Visit receivers will then indicate the Smoke Alarm.


You can carry out a number of checks yourself before sending a product for repair. 

Troubleshooting guide
Nothing happens when the transmitter is activated with the test button (2).
  • Change the battery. Use a Duracell MN1604, Energizer 522 (alkaline) or Ultralife U9VL-J (lithium).
The Visit Receivers occasionally indicate a fire alarm for no apparent reason.
  • Change the battery. Use a Duracell MN1604, Energizer 522 (alkaline) or Ultralife U9VL-J (lithium).
  • Change the Radio Key on all units in the system. For further information see Function/Radio Key
The Smoke Alarm can be activated with the test button (2) but the receivers are not responding.
  • Check that the Smoke Alarm’s antenna is straight and points to the floor.
  • Check that the receivers are not placed too far away by moving them closer to the Smoke Alarm.
  • Check the battery in the receiver.
  • Check that all units in the Visit System are set to the same Radio Key. For further information see Appendix/Further information/Settings/Radio Key.
The receiver signals when no transmitter is activated.
  • Change the Radio Key on all units in the relevant Visit System. There is probably another system nearby with the same Radio Key.
The Smoke Alarm beeps and chirps in a different way from that indicated above for no reason.
  • The Smoke Alarm is defective and needs to be sent for repair.
