Description

Radio Frequency Transmitters are best where security is needed (the signal is coded), where operation out of sight is required and where each function is operated by a separate button e.g. Door Openers, Door Latch Release Systems or Alarms. The range is up to 60 metres (A Standard Transmitter has a greater range than a Mini Transmitter). Operation is non-directional so accuracy in pointing is not required.
