The Alarm Loop Trigger offer museums, art galleries and other cultural attractions security and peace of mind ensuring that visitors return the Audio Guides to be charged and used by other guests.  The alarm loop trigger is great for high traffic venues where it is difficult to control how and when visitors enter and leave the facility.

The LT-200 Alarm Loop Trigger should be located near the loop sensing area. Each comes with a 12 VDC / 3.3A power supply.  The sensing range is easily adjustable using the coverage dial on the front of the alarm loop controller.  Typically located near or around exit ways, a beeping alarm will sound in the audio guide when visitors come within 2 M of the trigger zone, reminding visitors to return their Audio Guides.

The LT-200 Alarm Loop Trigger makes an outstanding choice for venues to minimize cost and ensure great continuing experiences for their guests.
