The JVA ZM20 is designed to be coupled with any standard electric fence energiser to power and monitor a perimeter security electric fence. In addition to the features of the ZM1 the ZM20 can be programmed to determine the position of a fault on the fence. Up to 20 different sectors within 1 zone can be differentiated. The
ZM20 powers both “ends” of the fence and determines the position of a fault using digital signal processing.

Benefits:

  • 2 to 20 Programmable Sectors
  • Reports the fault position (LCD and data output)
  • Cut or bridge alarm on sudden reduction in current
  • Monitors ground voltage, fence voltage and fence currents
  • Control and program via LCD keypad
  • Monitor via PC[2] (using Perimeter Patrol software)
  • 2 dry contact control inputs
  • Siren and Strobe switched 12V DC outputs
  • 3 form C relays with many programmable functions
  • Built in charger and space for a 12V 7.2aH backup battery
  • Run from 16Vac or 12Vdc external source
  • TCP/IP connectivity

The energiser must comply with IEC60335.2.76 (or similar) safety standard. Maximum energiser supported: 20 Joules.
