ACC-25/50ZS - Audio Command Center
25/50 Zone Splitter Voice Evacuation Control Panel

The Audio Command Center•25/50 Zone Splitter System (ACC-25/50ZS) is a state-of-the-art Emergency Voice Evacuation Panel (EVAC) capable of splitting up to 50 watts of audio power into up to eight zones. The ACC•25/50ZS provides the ability to record five field-programmable messages (up to 60 seconds total message duration) with an integral commercialgrade 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.

The ACC•25/50ZS is suitable for use as an adjunct (slave or stand-alone) to most UL-Listed Fire Alarm Control Panels (FACPs). An optional 25 watt, 25 VRMS audio amplifier is available for system expansion to 50 watts or as a secondary amplifier in jurisdictions requiring such backup. A 70.7 VRMS converter is also available for independently converting amplifiers to meet retrofit needs.

• 25 watts of audio power can be divided into eight Style Y (Class B) or four Style Z (Class A) zones, utilizing the zone splitter module (ACC-ZSM).
• Full manual control of all audio zones provided by zone page module (ACC-ZPM).
• Activation by the FACP using the ACS serial link and/or the five Command (CMD) inputs.
• ACS serial link compatible with all Fire•Lite FACPs, depending on function.
• FACP automatically directs the voice message to each or all audio zones.
• Paging by zone or All-Call.
• Full status indication (normal, active, fault) of each speaker zone.
