Edwards 3-ASU/4 Audio Source Unit W/ Local Microphone

The efficient EST3 audio system provides for intuitive local and remote audio control. For Mass Notification/Emergency Communications (MNEC), Life Safety, and other approved uses. EST3 audio builds from standard modules that fit together easily. Audio components use standard EST3 cabinets and power supplies.
Taking full advantage of digital technology, up to eight channels of audio sources. Transmit over a single twisted pair of wires or fiber optic cables between nodes. Coupling the inherent reliability and performance of zoned amplifiers.

The heart of the EST3 audio package is the Audio Source Unit (ASU). The Audio Source unit converts analog signals to digital signals. Onboard audio memory stores signal tones and/or alarm-alert verbal messages.
These digitally stored messages can – recorded onsite using standard PC audio components. Or downloaded from a library of pre-recorded messages and tones. Messages can be in any language or combination of languages. The ASU comes standard with two minutes of memory for tone and message storage. Available message memory expands easily to 100 minutes with the optional 3-ASUMX/100 memory expansion card.
Audio Source units support the connection of a local microphone, remote microphone, and telephone voice line. And Mass Notification/ Emergency Communication (MNEC) audio feed. With eight audio channels to choose from combinations of paging, alert, and evacuation signaling. Automatic messages are available for simultaneous delivery to different parts of a building or to different buildings.
Two main audio user interface modules, the paging microphone, and the firefighter’s telephone. Which supports three-state and four-state firefighter telephones. Available individually or in a set, EST3 audio modules open system design possibilities.
