24-HOUR PROTECTION OF METAL ENCLOSURES
APPLICATION
INSTALLATION
RECOMMENDED
PRODUCTS
Protecting against unauthorized access to a control panel, bell box or any metal
enclosure with a metal lid, eliminates the need for costly lining. Magnetic sensors
provide protection against tampering, as through the key hole or lock mechanism,
while shock sensors (see Glassbreak applications) provide protection against other
types of forced entry. The magnetic contacts are connected to the control’s 24-hour
loop.
Tamper Protection
Surface Mount: Use a Sentrol surface-mount, self-adhesive switch. With selfadhesive
contacts, such as the 1035, locate switch on side or bottom of cabinet
about 3/8" (0.95 cm) from front edge. Align magnet and mount. Test for operation
with ohmmeter.
Plunger Switch: Sentrol offers several plunger switches for tamper protection. All
are hermetically sealed and reed actuated for positive operation on seldom-used
enclosure openings.
1035 self-adhesive magnetic contact; 3012 clips on 0.04" to 0.07" (0.10 to
0.18 cm) thick sheet metal; 3012-1 clips on 0.08" to 0.12" (0.20 to 0.30 cm) thick
sheet metal; 3025T with shunt capability for servicing.
