Nemtek Druid 20 LCD Low Voltage Fence Monitor


This low voltage Druid 20LCD Fence Alarm Monitor is used to monitor fences in public areas or areas where an electric fence would be a legal concern, like a school. As the unit uses a pulse below 50V, animals or people touching the fence will not receive a shock, making it safe. An alarm will still be triggered if the wires are cut or shorted. This low voltage Fence Monitor allows the initial 1.5m of a fence in a public space to be monitored and the remaining height of the fence can still be electrified using a security energizer.



  • Monitors for continuity using safe 50V pulses
  • Can work in conjunction with other energizers to provide extra security above 1.5m.
  • The robust and flexible design is ideal for residential, commercial, industrial and high security sites
  • Four zones can easily be created by linking two D20 fence monitors together using the Druid four zone keypad
  • Detects a low voltage loop cut (open circuit or short)
  • Allows the installer to keep their fence compliant in public access areas
  • Connectable to armed response radio or GSM module
  • Lightning and power surge protection
  • Intelligent power saving to extend battery life
  • Optional keypad for controlling and programming the low voltage fence monitor.
  • The LCD background colour changes to easily identify the fence condition
