The Audio Command Center 25/50 Zoned System (ACC25/50ZS) is a state-of-the-art Emergency Voice Evacuation Panel (EVAC) capable of splitting 25 or 50 watts of audio power into up to eight speaker circuits (i.e., zones). The ACC25/50ZS records five field-programmable messages (up to 60 seconds total message duration) with an integral commercial-grade emergency communications microphone or from an external audio source. Significant technological enhancements set the ACC-25/50ZS apart from other EVAC panels — these include full supervision in both active alarm and standby conditions, supervision of amplifier outputs, field wiring, message generator, all tone generators, and the microphone. The integral power supply is capable of charging up to 18 AH batteries, which can be housed in the ACC-25/50ZS cabinet
