Fire-Lite Alarms
Emergency Command Center
The Emergency Command Center (ECC) is designed to be modular and flexible, to give users the maximum system integration and to be an easy and cost-effective preference for expansion. The unit’s modularity means multiple offices and safety stations can have direct access to announcing over the speaker system. This allows users to meet changing needs immediately and broadcast specific messages to specific zones for a wide range of events.
