Potter Electric EVD-M Electronic Vibration Detector Master Controller 2020250

Description

The EVD-M controller is a microprocessor controlled, vibration detector that incorporates advanced detection methods for identifying all common types of attacks. It 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. Small amplitude alarm sources must persist for 15 seconds before the EVD-M signals an alarm. Alarm contacts operate for a minimum of 2 seconds.
The EVD-M contains two sensitivity adjustments: one for EVD-M’s internal pickup, another one for a network of remote pickups. 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. The EVD-M signals wiring faults as alarms. A cover tamper and a back tamper protect the EVD-M from cover removal or prying. If either tamper on the EVD-M activates or any remote pickup signals tamper, the EVD-M will signal a tamper alarm condition. Tamper alarm contacts operate for a minimum of 2 seconds. If more than five remote pickups signal a tamper condition, the EVD-M will signal an alarm. The internal pickup of the EVD-M is always active, regardless of any tamper condition.
The model EVD-M controller provides a Form C, alarm contact for connection into the alarm protective circuit. Additionally, the EVD-M provides an independent, Form A, tamper alarm contact which can be wired as a separate 24 hour alarm circuit or wired in series with the alarm protective circuit. The EVD-M includes accessory terminals for an alarm condition remote annunciator, a tamper alarm remote annunciator, and a remote test input. The remote test input terminal permits the connection of dry contacts from any Underwriters Laboratories listed central station test unit. The remote test annunciator, model RTA, provides a normally open test switch and alarm and tamper alarm annunciators that interface directly to the accessory terminals of the EVD-M. In addition to its remote test capability, the EVD-M provides a magnetically activated test switch that permits testing of the installation. The EVD-M contains a multi-color LED to indicate system status.
