4 PELCO Manual C486M-B (9/95)
4.5 TAMPER SWITCH WIRING
The HS2500 is equipped with a tamper switch mounted
on the access door. This switch can be used as an alarm
closure to trigger an audible alarm and/or visual dis-
play on a monitor, indicating unauthorized intrusion of
the enclosure.
The tamper switch comes with wiring connections con-
sisting of 1/4" (.63 cm) quick connect terminals. It still
offers a “NORMALLY OPEN” and a “NORMALLY
CLOSED” contact as indicated on the switch body. In
addition, a “pull to cheat” feature allows the technician
to disable the audible alarm (in the case of the HS2500/
SPKR model) while having the door open for mainte-
nance.

5.0 CARE AND MAINTENANCE
Maintenance performed at regularly scheduled inter-
vals will help prolong the operational life and appear-
ance of the equipment.
Clean the Lexan window with a mild non-abrasive de-
tergent in water and a soft cloth regularly to help main-
tain picture clarity. For a heavily soiled window, use
vinyl cleaner.
CAUTION: When a single power source is
used for both the camera and accessories, the
camera power consumption must be taken into
consideration when determining the wire gauge.
Also, make certain that all electrical connec-
tions are done properly and meet electrical
codes.
