1 EVD-C AMPLIFIER 2020127
2 EVD-P PICKUP UNIT 2020126
1 TRANSFORMER 12V 20VA 5270080
1 BATTERY 6V 4AH 5130080
1 EOL RESISTOR ASSEMBLY 2020129

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

EVD-C PROCESSOR UNIT
The amplifier unit, model EVD-C, provides SPDT alarm contacts for connection into the alarm protective circuit. The EVD-C is housed in a metal cabinet protected by a cover tamper and a housing vibration detector. The housing detector is provided with a housing sensitivity control. A low voltage plug-in transformer and a regulated battery charging circuit maintain the standby battery at a fully charged state.

An auxiliary output is provided to power the APC-B (accumulator option) when required. The battery provides in excess of 80 hours standby operation even if the maximum 6VDC auxiliary output is utilized.

The EVD-C provides an AC on indicator (green LED), a test button, and an alarm indicator (red LED) for subscriber testing of the EVD-S System. Terminals are also provided for connection of a remote test unit, Model PTU-B, and/or connection of dry contacts from any Underwriters Laboratories Listed central station test unit.

From 2 to 15 pickup units may be connected to the EVD-C in a series supervised pickup loop. The supervision of the pickup loop is maintained by a factory adjusted DC differential circuit, which makes a compromise attempt of the pickup loop more difficult.

EVD-P PICKUP UNIT
Model EVD-P pickup units detect sound vibrations in the protected material. These signals are fed to the amplifier unit where the pickup loop sensitivity control determines the signal level necessary to create an alarm condition. A Model EOLR resistor assembly must be installed in the last EVDP. The pickup units are housed in a 4 1/4"H x 3"W x 1 1/4"D metal enclosure with cover and back tampers and are to be mounted with the speaker opening against the protected material.
