Features: Excellent shock resistance Rugged nylon molding Auto on (when voltage detected) Excellent drop resistance Good vibration resistance Loud sound alarm indication Built-in proving and self-test circuit High bright color-coded LEDS Works from standard 9V battery Interchangeable contact electrode Use in all whether conditions Compatible with all link sticks Lightweight, robust and compact Suitable for indoor and outdoor use Self (auto on) or manual arming Easy access to batteries Customized threshold on demand Auto off (if no voltage detected) The HVDs are self starting and automatically activated when the high voltage is applied to the contact electrode
A visual indication shows when the HVD is armed
These detectors are intended for use on sinusoidal 50 or 60 Hz high voltage systems
Utilized to determine if a system is live or not, so that it maybe safely earthed / grounded
When armed, the Green Leds flashes about twice per second
Is detected, the Red led flashes about twice per second and the buzzer also buzz intermittently.
