Flashing light indicates sharp drop in fence voltage
Volt alarm is simply hooked into the fence (does not require grounding)
Two different voltage levels can be set by the switch on the front panel:
- Stage 1: the control lamp flashes as soon as the fence voltage drops below 2,000 V
- Stage 2: the control lamp flashes as soon as the fence voltage drops below 4,000 V
Operation with a 3 V lithium battery CR2032 (included)
