General Information
The EVD-1, Electronic Vibration Detector, is listed by Underwriters Laboratories, Inc. for primary protection of Mercantile or Bank, safe or vault, ATM machines and supplementary protection of interior units such as fi le cabinets, display cases, walls and ceilings. The detector must be used with an appropriate UL listed control unit.
Features
- Detects all common threats to safes and vaults
- Sophisticated signal processing provides unprecedented sensitivity without 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
EVD-1 Controller
The EVD-1 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-1 detects a large amplitude alarm source it signals an alarm.

Determining The Number Of Detectors For A Safe Application
Refer to column one in Table 1 for the type of the safe in the application.
In column two fi nd the maximum linear distance from a detector to any point on
the protected surface. This distance is the detector range. Next, refer to
column one, (for steel safes), or column two, (for composite safes), in Table
2. Find the range of distances based upon the detector range that corresponds
to the safe in the application. Using the row of this range of distances,
determine the number of detectors from column three, (if safe has a single
door), or from column four, (if safe has double doors). For applications with
a larger distance than that shown in Table 2, consult Potter’s technical
support for assistance.

Determining the Maximum Linear Distance on a Safe
A rule of thumb for estimating the maximum linear distance from the
recommended detector location to any point on the protected surface is:
Example: h = 62″ w = 55″ d = 29″
- X1 = 62″+ 55″ (X1 = 117″)
- X2 = (2 x 29″) + 55″ (X2 = 113″)
- X = 113″
- J = 55″ + 29″ (J = 84″)
- D = 113″
- Compute X1 = h + w
- Compute X2 = 2d + w
- Find X = minimum ( X1, X2 )
- Compute J = w + d
- Find D = maximum ( X, J )
Where: h = Safe Height
w = Safe Width
d = Safe Depth
D = Maximum Linear Distance
This rule of thumb is valid for most available safe sizes. However, if any one dimension is very large or very small when compared to the other two dimensions, the safe may not follow this rule. In those cases, contact Potter’s technical support for assistance. Table 3 lists some common safe dimensions and their maximum linear distances when detectors are installed in recommended locations.

EVD-1 Mounting Detector on Safe Door
The EVD-1 can be ounted on the safe door (single door safes only).
When the detector is mounted on the safe door, the maximum linear distance
decreases to 73.5″ from the sensor location, through the hinges, to all points
on the safe body.
Typical UL Complete Safe Installations
- Install 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 or UL listed, ordinary use contacts on the inside of the safe.
- Wire detectors and safe door contacts as shown in installation instructions using high security cable.
- Listed power supply or control unit must provide at least 4 hours of standby power for mercantile alarms and 72 hours of standby power for bank vault alarms.
Typical UL Complete Vault Installations
- Install in accordance with Underwriter Laboratories’ standard UL 681.
- Install EVD-1 detectors on interior walls, ceilings, and fl oors, spaced as shown in Figure 1. Refer to Table 4 for maximum spacing on various materials.
- A detector must be installed on the vault door if the net steel thickness is less than 1½ inches.
- Wire detectors and door contacts as shown in installation instructions.
- Listed power supply or control unit must provide at least 4 hours of standby power for mercantile alarms and 72 hours of standby power for bank vault alarms.
EVD-1 Wall Protection
Figure 1 shows the rectangular areas of 100% coverage when detectors are
installed adjacent to one another. The detector spacing is the sensor center
point distance between adjacent detectors. The detector spacing is the same
as the width of the rectangular area of 100% coverage.
Table 4 lists the dimensions of the rectangular areas of 100% coverage on
continuous surfaces for several materials and sensitivity settings. When a
surface extends around a corner via a solid connection, detector coverage
extends into that surface, but the coverage is reduced to 3/4 of the remaining
detector range. All joints, cracks, and corners dampen structure borne
vibrations. Vibration transfer across these imperfections must be tested to
ensure complete coverage within the detector’s range.
Modular constructions require one detector per panel and must be constructed
of the materials listed in Tables 1 and 4.
