Potter Signal EVD-1 Electronic Vibration Detector

The EVD-1 Electronic Vibration Detector, is listed by Underwriters Laboratories, Inc. for primary protection of Mercantile or Bank, safe or vault, ATM machines and supplementary protection of interior units such as file cabinets, display cases, walls and ceilings. The detector must be used with an appropriate UL listed control unit.

The EVD-1 controller detects short duration, large amplitude signals like those produced in attacks from explosions, hammering or chiseling. It also detects long duration, small amplitude signals like those produced in attacks from torches, thermic lances, drills, grinders or cutting discs. As soon as the EVD-1 detects a large amplitude alarm source it signals an alarm.
