JVA Fence Monitor BM1
When connected to the end of the fence (return wire) the BM1 can monitor one complete circuit (zone) of electric fence.
This monitor can be powered from a 12V power supply, or a 12V battery. If you need the monitor to operate during a power failure, consider using a 12V lead acid battery that is being kept charged from a battery charger or solar panel.
The BM1 is intended to be used with pulsed type electric fence energisers with output voltages of 10kV or less. The energiser should conform to IEC60335.2.76 or similar.
The BM1 includes two switched 12V outputs:
It also has an internal Beeper, which can be muted with a shunt (supplied)
