5.0 INSTALLATION
5.1 WALL/CEILING MOUNTING
To mount the enclosure to a wall or ceiling, perform
the following steps:
1. Using the template supplied, mark the hole loca-
tions and area to be cut out.
2. Drill mounting holes and cut wall/ceiling for en-
closure body. Note the angle of the enclosure in
relation to the mounting flange and remove suffi-
cient material behind the wall to clear.
3. Insert the enclosure into the opening and attach with
the required fasteners.
4. Install conduit fittings (not supplied) into holes on
rear access plate and run required wiring through
fittings.
5. Access to the interior of the enclosure can be gained
from either the front (window) or rear by remov-
ing the end plates. The end plates are secured by
four (4) 1/4-20 “Tampruf” screws (four (4) each
end). A special socket is provided (fits 1/4” square
drive). The end plates are symmetrical and may be
swapped end for end depending on the installation.
6. Remove the camera sled from the enclosure. Mount
the camera/lens to the sled.
7. Make all appropriate connections (i.e., camera
power, video (coax), and lens).
8. Replace the camera/lens/camera sled assembly
back into the enclosure and tighten the 1/4-20 screw
to secure the sled in place.
9. Replace the end plate(s) and check that all compo-
nents clear. Secure with the 1/4-20 “Tampruf”
screws provided.
NOTE: The eight (8) fasteners required to se-
cure the HS4000TW Series enclosure to a wall
or ceiling (minimum 3/8” diameter recom-
mended) are not supplied.
Before installing the HS4000TW Series enclosure in a
wall or ceiling, make certain that the mounting surface
is able to support the full weight of the enclosure plus
the camera and lens.
5.2 TAMPER SWITCH INSTALLATION
The HS4000TW High-Security enclosures come
stanmdard from the factory with a tamper switch
mounted on the secure access cover.
Should it become necessary to install a replacement
switch, reference Figure 2 and perform the following
steps:
1. Open the enclosure by removing the end plate from
the desired “alarmed” opening.
2. Install the bracket so that the mounting studs go
through the slots in the bracket.
NOTE: The slot in the bracket allows the switch
to be used against either the 1/2" (1.27 cm) thick
lexan window or the .134" (0.34 cm) thick metal
plate.
3. If the switch is to be used against the metal plate,
slide the bracket so that the studs are at the end of
the slot that is furthest from the switch plunger.
4. If the switch is to be used against the Lexan win-
dow, slide the bracket so that the studs are at the
end of the slot nearest the switch plunger.
5. When reinstalling the front/rear plate, position the
plate flush with the end of the enclosure body.
5.3 TAMPER SWITCH WIRING
The tamper switch comes with both a “Normally Open”
and a “Normally Closed” contact.
For a “Normally Open” circuit, use the “open” and
“common” terminals; for a “Normally Closed” circuit,
use the “closed” and “common” terminals.
