Outstanding Features Digital Audio EST3 system components are arranged in layers,starting with the EST3 digitized audio can deliver up to eight audio messages backbox and finishing with inner and outer doors. Cabinets are simultaneously over a single pair of wires!This is plenty of capacity available with room for up to 20 modules and system batteries up for both live and pre-recorded messages. EST3 easily supports to 65 AH.A single 24-volt battery can act as the secondary power the needs of mass notification messaging, and fire alarm messag- supply for all four internal power supplies.Once the backbox is ing by providing the ability to bring not only pre-recorded messag- installed, up to four power supplies can be installed in the chassis es but also live voice messaging supporting not only evacuation assembly.The power supplies use a unique paralleling arrange- announcments but the messaging needed to support the risks ment that ensures the optimum use of each supply.
