EST3's user interface offers simple yet powerful control and display in any situation. Fingertip operation and intuitive feedback provide the big picture whether the user is in the midst of a crisis, or simply performing routine maintenance. And because EST3 supports a full eight channels of multiplexed audio, there's plenty of capacity to handle communications. Firefighters, emergency response personnel, and building occupants can all keep in touch when seconds count and information can save lives.

Its modular design is what makes EST3 a favorite with building owners, installers, and property managers. System components are arranged in layers for easy access. Key components feature removable terminal blocks and simple plug-in connectors, and its modular design means the system can easily keep pace with even the most radical changes to building floor plans.
