The EFDAU2000 voice distributed amplifier unit is an all-in-one, wall mounted voice alarm system that enables the user to issue amplified pre-recorded messages to building occupants following fire detection. These can be supplemented by live spoken messages from the fire service or management suite. The messages issued can be used to instruct people to help control the flow in stairwells and corridors allowing a safe and rapid evacuation of all building occupants.
Network ready, the EFDAU2000 has the capacity for up to 10 amplifier cards, with a mix of Eaton’s EF-D150 and EF-D500 possible. The panel has 12 audio inputs and internal storage for up to 64 recorded messages. With a maximum power of 2000W, this compact wall-mount enclosure provides integrated audio-over-IP networking (up to 32 panels in large decentralized systems), powerful audio processing, and integrated battery charger.
EFDAU2000 provides a complete voice alarm solution for a range of centralised and decentralised public address / voice alarm applications.
