Protecting Movable Objects Protecting A Valuables Drawer
APPLICATION 1
Surface Mount Contacts
Valuable coin collections, silverware and jewelry can be protected by arming a storage drawer with either recessed or surface mount magnetic contacts.
INSTALLATION
Because of the difficulty of working with a screwdriver inside a drawer, use a self- adhesive switch. Be certain to clean mounting surfaces with alcohol before attaching contacts. Wide gap switches should be used on steel file cabinets and desk drawers because steel will cut operating distance in half.
Choose mounting locations where switch and magnet will not interfere with operation of drawer. Clearance between moving and non-moving parts may vary.
Install Interlogix switch in cabinet and magnet on drawer. Or, mount switch and magnet on outside of drawer. If wide gap switch is used, align labels on switch and magnet so "Sentrol" reads in same direction for both (switch is polarity sensitive).
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
Recessed Contacts
Valuable coin collections, silverware and jewelry can be protected by arming a storage drawer with either recessed or surface mount magnetic contacts.
INSTALLATION
Recessed mounting is not recommended (and usually not possible) on metal drawers because the metal is usually too thin. On metal drawers, use Sentrol self- adhesive contacts. Allow for a 50% reduction in gap distance if mounted on steel.
For drawers in which contacts can be recessed, select appropriate switch.
Drill vertical hole in side of drawer. Coat magnet with RTV mounting compound and insert in hole.
Coat switch with RTV mounting compound and attach to cabinet perpendicular to magnet. Magnet must not be centered below switch, but rather, near end of switch. If wide gap switch is used, red tip of magnet must be away from switch.
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.
