"Silent" Alarm for Banks and Jewelry Stores


Banks, jewelry stores, and other retail facilities with cash and valuables can be protected with a manually operated Interlogix switch. Sentrol’s 3040 and 3045 feature internal magnetic contacts and an actuating lever with a magnet cradled in it. When the lever is pulled, the SPDT circuit closes or opens, activating the alarm. Mounted under a counter top or inside the kneehole of a desk, the device offers protection for employees in potentially high-risk businesses.

Note: The 3040 has a separate latching LED circuit. It must be powered and reset by a push-button +5 to 12 VDC source in or mounted outside the alarm panel. The 3045 has no latching LED.


Determine the best location for the actuating lever. It is most effective when mounted out of view but within convenient reach of the user.

Make sure you allow at least 3" (7.62 cm) of clearance above the mounting surface to accommodate the actuating lever once it is fully open. The device can be mounted horizontally or vertically.

Temporarily mount unit with tape and test for ease of operation. Mark holes for screws and a hole for leads.

Drill pilot holes or start screws. Connect leads to terminal block inside housing. Snap cover plate in place.

Test unit. Handle pulled approximately 30˚ from the normal locked position will activate alarm circuit and LED circuit — LED will light. With handle open, reset LED circuit by interrupting power to LED circuit. LED will go out.

Close handle. Device is now fully re-armed.
