3 .1 .3 JMBx-ZM50
The JMBx-ZM50 contains our patented loop monitor with Distant Fault De
-
tection (DFD™). The loop, or loops, of live wires may run down and back on
the same fence or all the way around a property.
While previous fence loop monitors suffered from a range limitation of
approximately 10km of fence or 30km of wire, DFD™ has greatly increased
this range. JMBx-ZM50 features include:
• Can split a single fence into up to 50 sectors
• Can report the position of a fault as a percentage of overall fence
length.
• Short sectors can be accurately defined using JVA sector dividers. See
section 9.2.22 on sector dividers.
• ELV open circuit detection.
