Potter EVD-1 Electronic Vibration Detector

EVD 1 VIBRATION SYSTEM x 3.26 W x 1.20 D H x 8,3cm W x 3,0cm D and ULC Listed EVD 1 0.64 lbs 0,29 kg Die cast aluminum Stamped Steel 22 Gauge Input VDC to 16.0 VDC 12 VDC Nominal 0.1 V ripple If the EVD is going to be powered by auxiliary power of a burglar panel and the panel has ground fault detection it may be to power the EVD from a separate UL 12 VDC power supply Alternately the safe be insulated from ground Current Supply Voltage 12.0 VDC Standby Condition 26 mA Condition 24 mA Condition 34 mA model RTA connected add 10 mA in Tamper and 10 mA in Alarm Condition Current Supply Voltage 16.0 VDC Standby Condition 26 mA Condition 24 mA Condition 34 mA model RTA connected add 14 mA in Tamper and 14 mA in Alarm Condition No Information Detector Safe Pak EVD 1 Detector Security Safe Contact Equipment Remote Test Annunciator Security Cable Cable equipment required for UL safe complete installation EVD 1 is a stand alone detector For applications more than one detector the EVD 2 may be more For more information on the EVD 2 system bulletin no 8870015 Data Relay Form C 2.0 Amps at 30 VDC Contact Form A 2.0 Amps at 30 VDC Information EVD 1 Electronic Vibration Detector is listed by Underwriters Inc for primary protection of Mercantile or Bank safe vault ATM machines and supplementary protection of interior units as le cabinets display cases walls and ceilings The detector must used with an appropriate UL listed control unit Detects all common threats to safes and vaults Sophisticated signal processing provides unprecedented sensitivity false alarms Low cost stand alone system Reliable sensitive piezo sensor technology Integral multi color status LED Built in test circuit Remote test and annunciator capabilities Supervised microprocessor Independent tamper output On board test point facilitates installation and service Built in accumulator Controller EVD 1 controller detects short duration large amplitude signals those produced in attacks from explosions hammering or It also detects long duration small amplitude signals like produced in attacks from torches thermic lances drills grinders cutting discs As soon as the EVD 1 detects a large amplitude alarm it signals an alarm Construction Requirements 1 Maximum Linear Distances from Detector to Any Point the Protected Surface Construction Linear From to Any Point Pickup RV1 inches Safes

continuous surfaces for several materials and sensitivity settings a surface extends around a corner via a solid connection detector extends into that surface but the coverage is reduced to 3 4 the remaining detector range All joints cracks and corners dampen borne vibrations Vibration transfer across these imperfections be tested to ensure complete coverage within the detector range constructions require one detector per panel and must be of the materials listed in Tables 1 and 4 1 Wall Protection Diagram Mounting Detector on Safe Door EVD 1 can be ounted on the safe door single

in accordance with Underwriter Laboratories standard UL 681 Install EVD 1 detectors in recommended locations at recommended spacings Install UL listed high security contacts on the exterior of the safe UL listed ordinary use contacts on the inside of the safe Wire detectors and safe door contacts as shown in installation using high security cable Listed power supply or control unit must provide at least 4 hours of power for mercantile alarms and 72 hours of standby power bank vault alarms UL Complete Vault Installations Install in accordance with Underwriter Laboratories standard UL 681 Install EVD 1 detectors on interior walls ceilings and oors spaced shown in Figure 1 Refer to Table 4 for maximum spacing on materials A detector must be installed on the vault door if the net steel thickness less than 1 inches Wire detectors and door contacts as shown in installation instructions Listed power supply or control unit must provide at least 4 hours of power for mercantile alarms and
