INSTALLATION
PROTECTING MOVABLE OBJECTS
PROTECTING A CHINA CABINET
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.
Choose appropriate surface mount switch. Where unobtrusive installation is
desired and space is at a premium, use 1145W ultra miniature wide gap switch.
RECOMMENDED
PRODUCTS
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.
