General Information

The EVD-2, Electronic Vibration Detector System, 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 file cabinets, display cases, walls and ceilings. The System must be used with an appropriate UL listed control unit.
The standard EVD-2 system consists of a model EVD-M controller and a model EVD-R remote pickup.

Features

• Detects all common threats to safes and vaults.
• Sophisticated signal processing provides unprecedented sensitivity without false alarms.
• Expandable system allows up to 15 remote pickups, (Model EVD-R).
• Reliable, sensitive piezo sensor technology.
• On board high security safe contact interface.
• Integral, multi-color status LED.
• Built in test circuit on both controller and remote pickups.
• Remote test and annunciator capabilities.
• Supervised microprocessor.
• Independent tamper output.
• On board test point facilitates installation and service.
• Built in accumulator.

EVD-M Controller

The EVD-M 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-M detects a large amplitude alarm source it signals an alarm.
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.

Safe Construction Requirements

Table 1. Maximum linear distances from detector to any point on the protected surface
Determining the number of detectors for a safe application

Steel Safes

Body: Minimum 1/4″ Door: Minimum 1/2″

| 96 inches
Composite Safes

Body: Minimum 16 gauge steel over 3″ composite material

Door: minimum 1/4″ steel over 3″ composite material

| 110 inches

Refer to column one in Table 1 for the type of the safe in the application. In column two find 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). In some single detector applications, the EVD-2 system may be used to protect multiple safes via a combination of an EVD-M and multiple EVD-R remote pickups. For applications with a larger distance than that shown in Table 2, consult Potter’s technical support for assistance.

*Steel Safe Construction:

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″

1. X1 =62″+ 55″ (X1 = 117″)
2. X2 =(2 x 29″) + 55″ (X2 = 113″)
3. X = 113″
4. J = 55″ + 29″ (J = 84″)
5. D = 113″
6. Compute X1 = h + w
7. Compute X2 = 2d + w
8. Find X = minimum ( X1, X2 )
9. Compute J = w + d
10. 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.

Table 3
Typical Safe Exterior Dimensions and Maximum Linear Distances

Height (inches)| Width (inches)| Depth (inches)| Volume (cu. ft.)| Maximum Linear Distance (inches)
---|---|---|---|---
25| 21| 21| 6.38| 46
32| 25| 25| 11.57| 57
42| 31| 29| 21.85| 73
52| 31| 29| 27.05| 83
62| 31| 29| 32.26| 89
62| 55| 29| 57.23| 113
64| 31| 29| 33.30| 89

Table 4 EVD-2 Mounting Detector on Safe Door

EVD-2 Mounting Detector on Safe Door

The EVD-2 can be mounted 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

1. Install in accordance with Underwriter Laboratories’ standard UL 681.
2. Install evd-m and evd-r detectors in recommended locations at recommended spacings.
3. Install ul listed, high security contacts on the exterior of the safe or ul listed, ordinary use contacts on the inside of the safe.
4. Wire detectors and safe door contacts as shown in installation instructions, using high security cable.
5. 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

1. Install in accordance with Underwriter Laboratories’ standard ul 681.
2. Install evd-m and evd-r detectors on interior walls, ceilings, and floors, spaced as shown in figure 1. Refer to Table 4 for maximum spacing on various materials.
3. A detector must be installed on the vault door if the net steel thickness is less than 1 1/2 inches.
4. Wire detectors and door contacts as shown in installation instructions using high security cable.
5. 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-2 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.
