Some exit devices are electronically operated using sensors or alarms. The main purpose of installing them is to provide safety and ample security inside and outside the premises where they are installed or mounted. These implements are considered vital door hardware or accessories that must be used in schools, commercial establishments, hospitals, offices and other areas normally flooded with people.
