PROTECTING A “VALUABLES” DRAWER<br />
Recessed Contacts<br />
Valuable coin collections, silverware and jewelry can be protected by arming a<br />
storage drawer with either recessed or surface mount magnetic contacts.<br />
Recessed mounting is not recommended (and usually not possible) on metal<br />
drawers because the metal is usually too thin. On metal drawers, use Sentrol selfadhesive<br />
contacts. Allow for a 50% reduction in gap distance if mounted on steel.<br />
For drawers in which contacts can be recessed, select appropriate switch.<br />
Drill vertical hole in side of drawer. Coat magnet with RTV mounting compound<br />
and insert in hole.<br />
Coat switch with RTV mounting compound and attach to cabinet perpendicular to<br />
magnet. Magnet must not be centered below switch, but rather, near end of<br />
switch. If wide gap switch is used, red tip of magnet must be away from switch.<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 />
