GENERAL INFORMATION
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 protec-
tion 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 (accu-
mulator 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 Laborato-
ries 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 EVD-
P.
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.

INSTALLATION (SEE FIGS. 1, 2, 3, 4, 5, 6 and 7)
The device must be installed in accordance with all applicable local codes. Battery must be charged for 48 hours before
putting unit into service.
1. Mount EVD-C.
2. Mount pickup units and wire according to installation drawing.
3. See Figs. 2 and 4 for connection of remote test unit Model PTU-B and/or central station test unit, if applicable.
4. Connect BLACK battery lead to NEGATIVE battery post and RED battery lead to POSITIVE battery post.
5. Plug transformer to unswitched 110VAC outlet and apply 12VAC to terminals 1 and 2 of EVD-C.
NOTES: A. Maximum of 15 pickups on loop.
B. Pickup loop not to exceed 1,000 ft. of #22 AWG, two conductor shielded cable.
SENSITIVITY ADJUSTMENTS:
1. Adjust the pickup loop sensitivity control to 1/2 scale (6 o'clock position).
2. Perform simulated attack tests on all accessible surfaces, protected by EVD-P's, utilizing a plastic mallet or the plastic
handle of a large screwdriver. An alarm condition (as indicated by the red LED) must occur.
NOTE: Extreme care should be exercised so that the protected surfaces are not marred or damaged while performing
attack test.
If necessary the pickup loop sensitivity may be adjusted to obtain reliable test results. The sensitivity control may not
be adjusted to less than 1/2 scale for safe applications.
3. Perform attack test on EVD-C housing and adjust “housing” sensitivity control for desired protection.
CAUTION:
Housing sensitivity is adjustable to an “off” condition. Never leave the unit in this unprotected condition!
TESTING
Pressing Test button on front of EVD-C induces a test signal into the EVD-C amplifier. An alarm condition indicated by a
Red LED adjacent to the test button must occur. If a Model APC-B Accumulator has been installed, the test button must
be held in approximately 30 seconds before the unit will go into the alarm condition.
Operation of the system can be verified from a remote location by use of an optional PTU-B and/or a Central Station Test
Unit.
The subscriber must be instructed to test the system each time the alarm is set per instructions on front of EVD-C.
UL CERTIFICATED SAFE APPLICATIONS
The following conditions must be met to qualify for an Underwriters Laboratories complete safe certificate:
•A minimum of 2 EVD-P pickup units required for all applications (see exception).
•COMMERCIAL BURGLARY SAFES must be constructed of a minimum 1/4" steel for the body of the safe and 1/2" for
the door. Burglary safes exceeding 20 cubic feet in size must have an additional EVD-P pickup for every additional 10
cubic feet.
•COMMERCIAL FIRE SAFES exceeding 44 cubic feet in size must have an additional EVD-P pickup for every additional
22 cubic feet.
•(EXCEPTION) UL LISTED TRTL and TXTL SAFES: One pickup may provide protection for a safe not exceeding 36 cubic
feet. An additional pickup unit is required for each additional 36 cubic feet or portion thereof.
