The EVD-M 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-M detects a large amplitude alarm source it signals an alarm.
The EVD-M controller supports up to 15 EVD-R remote pickups, (or may be used as a stand alone unit), and fully supervises EVD-R wiring.
