OPERATION
The following operating features and conditions exist with the switch and magnet units in its
secured condition (positioned, mounted, and wired correctly):
• Triple Biased Switch Operation - The three biased switches will be in the closed position when
the switch is in its secured condition. Opening of the door or removal of the switch unit or mag-
net unit will cause an alarm condition.
• Pry Tamper Operation - The pry tamper switch will be in the closed position when the switch is in
its secured condition (depressed by tamper screw). Removal of the switch unit from the mount-
ing surface will cause a tamper alarm condition.
• Magnetic Tamper Operation - applying an external magnet in an attempt to defeat the switch will
operate a normally closed switch causing a magnetic tamper alarm condition.
WIRING
Warning: A color code wire designation is located on the wire ends. Be sure to label wires
before shortening lead lengths.
If the alarm system provides for a 24-hour supervision circuit, connect the magnetic and pry
tampers to that circuit. This wiring confi guration will signal an alarm condition when the switch unit
is tampered with, whether the door is open or closed. Figure 2a. shows an example of this wiring
confi guration.
If the alarm system does not provide for a 24-hour supervision circuit, connect the magnetic and
pry tampers in series with the switch in the alarm protective circuit. This wiring confi guration will
create an alarm condition when the switch unit is tampered with, but only when the door is closed
in the secure position. Figure 2b. shows an example of this wiring confi guration.
Either confi guration of connecting the HSC supervisory circuits complies with Underwriters' Labora-
tories UL 681 installation standards.
