FIRE PROTECTION--Advancing the capabilities of the Simplex 4100U fire alarm system, SimplexGrinnell introduces the InfoAlarm[TM] Command Center. The multi-line display and soft control keys enable system users, maintenance personnel, and first responders to access clear information that can identify the location, nature, and severity of an emergency or fire-alarm system condition. Further support for fire protection and command operations can be achieved by placing remote, compact-sized InfoAlarm Command Centers in building entrances, lobbies, and other locations. 4100U InfoAlarm Command Center by SimplexGrinnell.
