An Audible and Visual Beacon that will alarm for 72 hours. The MRA™AB Model is the ideal choice where the potential for a protracted emergency exists and the lack of motion feature is not desired. When an emergency occurs, the wearer simply pushes the Alarm Button, causing the device to sound its alarm for up to 72 continuous hours. Other AB Models can be stored in each 'Cache' where they can be activated and dropped to establish a 'breadcrumb' trail for rescue personnel to follow. In addition to the loud, audible alarm, ultra-bright LEDs will pulse and strobe, giving rescue personnel a visual beacon to track in low-light conditions.

The MRA™Manual Operation Model M was specifically designed for Mining and Tunneling Operations for the wearer who needs to control the on/off status of the device manually. The MRA™ Model M is a new generation Mine Rescue Alarm™ that sounds a loud easily recognized signal approximately 60 seconds after the wearer becomes motionless.This unique device incorporates an innovative mechanical design with advanced data processing circuitry to bring you the most reliable and rugged Mine Rescue Alarm available. In units so equipped, a temperature sensor sounds three audio beep tones when excessively high temperatures are experienced. ( The MRA™ Model M is also available in 30, 90, and 120 second lack of motion alarm times)

The MRA™ Model A is designed to be automatically activated into the 'Sensing Mode' (motion sensing mode)turned 'ON' when removed from the MRATM storage position, whether it is a transportation or a fixed storage position.When removed from the storage position, the tether will tighten and the Tally Key will automatically pop off. If the tether is not anchored, the wearer can simply pull on the tether and the Tally Key will pop off. The Tally Key can then be given to the Safety Officer to be placed on the Tally Board for accountability and storage until the wearer returns to the point of entry. The Tally Key has an adjustable tether for ease of use. The tether can be adjusted from approx. 18" to 36" in length. This allows for easy utilization for anchoring. Tally Keys are available with various length tethers to facilitate various operational needs. ( The MRA™ Model A is also available in 30, 90, and 120 second lack of motion alarm times)
