Protecting Movable Objects Protecting A China Cabinet

APPLICATION 1

Recessed contacts

Valuable china and other collectibles can be protected by arming a china cabinet with either recessed or surface mount magnetic contacts.

Notes:
• Alarm both doors if protecting a two-door cabinet. Wire Interlogix switches in series.
• Do not place contacts in hinged portion of door since door could be opened wide before switch would trip.
• For aesthetic reasons, recessed installation is more desirable than surface mount

INSTALLATION

Choose appropriate concealed contact.

Select positions for magnets in doors, switches in cabinets.

Drill vertical hole in top of door. Coat magnet with RTV mounting compound and insert in hole. If wide gap switch is used, observe correct polarity by mounting bare magnet with red end toward switch end with wires.

Drill vertical hole in cabinet for switch. Also, drill a hole at an angle from the inside of the cabinet to meet the switch hole so wires can be run to the switch.

Coat switch with RTV mounting compound. Insert switch in hole, fishing wires through to inside of cabinet. Route wires in joint of cabinet, around top of cabinet to back. Drill exit hole for wires through back of cabinet.

Test for continuity with ohmmeter. Install in alarm loop. If higher security is desired, install on 24-hour loop. Provide a shunt switch in the circuit to permit access as needed.

APPLICATION 2

Surface mount contacts

Valuable china and other collectibles can be protected by arming a china cabinet with either recessed or surface mount magnetic contacts.

Notes:
• Alarm both doors if protecting a two-door cabinet. Wire switches in series.
• Do not place contacts in hinged portion of door since door could be opened wide before switch would trip.
• For aesthetic reasons, recessed installation is more desirable than surface mount.

INSTALLATION

Choose appropriate surface mount switch. Where unobtrusive installation is desired and space is at a premium, use 1145W ultra miniature wide gap switch.
 
Select positions for magnets in doors, switches in cabinets.

Mount switches and magnets. If wide gap or high security switches are used, align labels on magnet and switch so they read in same direction (switches are polarity sensitive). If using H-Series, observe minimum gap distances.

Route wires in joints of cabinet, around top of cabinet to back. Drill exit hole for wires in back of cabinet.

Test for continuity with ohmmeter. Install in alarm loop. If higher security is desired, install on 24-hour loop. Provide a shunt switch in the circuit to permit access as needed.
