An easy-to-use one-way messaging pager, ruggedized, and equipped with a smart personal alarm capabilities. Ascom a51 is a rugged one-way messaging pager designed with advanced personal safety in mind. If for some reason you cannot trigger a distress alarm manually, this smart pocket-sized pager can automatically trigger “man-down” or “no-movement” alarm signals. For extra safety, a pull-cord triggers a distress alarm if the handset is forcibly taken from staff. The Ascom a51 also features an optional on-site positioning function. The location can be transmitted together with distress signals, helping the rescue team to determine where the incidence has occurred.
