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.


The antenna (1) should be straight and pointed directly down to achieve best coverage between Smoke Alarms and receivers within the Visit System.
