SimplexGrinnell of Westminster, Massachusetts, has introduced the Simplex 4003 EC Multi-Function Voice Control Panel, which is designed for voice communications in smaller, single buildings. It is suited to school auditoriums, university buildings, churches, and other areas where voice communications are required by code. The panel can add voice messaging capability to non-voice fire alarm control panels. It can be activated from virtually any Simplex fire alarm panel or from other manufacturers’ panels. Multiple units can be interconnected to provide systemwide emergency communications. The control panel accepts voice input from a central command center and has the ability to override local messages when an emergency message is initiated.
