Added Protection Through Textual Alarm Notifications

In areas with high noise levels or poor acoustics and audio intelligibility such as train stations, manufacturing plants and airports, it can be difficult for building occupants to hear and understand alarm messages and emergency instructions. It’s also vital to convey critical information to the hearing-impaired. The Simplex TrueAlert Text Messaging Appliance provides the solution with a high-visibility, LED text message board that delivers an extra level of protection by adding textual alarm notifications and emergency instructions. In addition, during normal facility operation, the Text Messaging Appliance can be used for the routine display of information, such as news, announcements, school lunch menus and more.
