Pelco Manual C497M-D (1/96)

The HS4000 High-Security enclosures come standard
from the factory with a tamper switch(es) mounted on
the secured access door. Refer to Section 4.1 for wir-
ing.

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.

The tamper switch comes with both a “Normally Open”
contact 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.

Regularly scheduled maintenance will help prolong the
appearance of the equipment.

Clean the window regularly with a soft cloth and mild
nonabrasive detergent in water to help maintain picture
clarity.
