RECOMMENDED DETECTOR LOCATIONS
Single Detector Applications
All safe applications must have at least an
EVD-M or an EVD-R on the body of the
safe. When only one detector is required
on a safe, mount the detector on the
exterior of the safe on the door hinge
side, near the front edge and centered
within the height of the safe. (Ideally,
mount the detector’s sensor center point
2 inches in from the front edge of the
safe on the centerline of the safe’s
height, refer to Figure 11). Figure 6.
shows the recommended detector
location of a safe application requiring
one detector. Safes with double doors
require a minimum of two detectors,
even if the dimensions of the safe
conform to the requirements for the
use of a single detector.
Two-Detector Applications
When two detectors are required on a
safe, mount the first detector as recom-
mended for a single detector installation.
Mount the second detector on the
opposite side of the safe, at the same
height and with the same front edge
offset as the first detector. Safes with
double doors that conform to the
dimensional requirements for the
use of one or two detectors should
be protected in this fashion. Figure 7.
shows the recommended detector
locations of a safe application requiring
two detectors. Figure 8. shows the
recommended detector location(s) of a
safe application with double doors.
Multiple Detector Applications
When more than two detectors are
required on a safe, mount the first two
detectors as recommended for a two-
detector application. Mount the remaining
detectors on the remaining surfaces,
centered and spaced evenly to ensure
complete detector coverage. Alternately,
mount a detector centrally on the safe
door and the remaining detectors centrally
on the remaining surfaces, evenly
spaced.
