PROTECTING MOVABLE OBJECTS<br />
PROTECTING A CHINA CABINET<br />
Recessed contacts<br />
Valuable china and other collectibles can be protected by arming a china cabinet<br />
with either recessed or surface mount magnetic contacts.<br />
Notes:<br />
• Alarm both doors if protecting a two-door cabinet. Wire switches in series.<br />
• Do not place contacts in hinged portion of door since door could be opened<br />
wide before switch would trip.<br />
• For aesthetic reasons, recessed installation is more desirable than surface mount<br />
INSTALLATION<br />
RECOMMENDED<br />
PRODUCTS<br />
Choose appropriate concealed contact.<br />
Select positions for magnets in doors, switches in cabinets.<br />
Drill vertical hole in top of door. Coat magnet with RTV mounting compound and<br />
insert in hole. If wide gap switch is used, observe correct polarity by mounting<br />
bare magnet with red end toward switch end with wires.<br />
Drill vertical hole in cabinet for switch. Also, drill a hole at an angle from the<br />
inside of the cabinet to meet the switch hole so wires can be run to the switch.<br />
Coat switch with RTV mounting compound. Insert switch in hole, fishing wires<br />
through to inside of cabinet. Route wires in joint of cabinet, around top of cabinet<br />
to back. Drill exit hole for wires through back of cabinet.<br />
Test for continuity with ohmmeter. Install in alarm loop. If higher security is<br />
desired, install on 24-hour loop. Provide a shunt switch in the circuit to permit<br />
access as needed.<br />
