Fire Lite Alarms ACC-25/50DA Distributed Audio Panel
The Fire Lite ACC-25/50DA is a compact Distributed Audio (DA) panel which is designed to interface with the Audio Command Center 25/50 (ACC-25/50) Series audio panels to distribute audio in systems that require more than 25 watts. The ACC-25/50DA is offered in a self-contained modular design that includes a single channel, 25 Watt, 25 VRMS audio amplifier. An optional 25 Watt, 25 VRMS audio amplifier is available to expand the ACC-25/50DA to 50 Watts (providing dual 25 Watt speaker circuits) or as a secondary, backup amplifier. The ACC-25/50DA can be used to distribute voice evacuation audio throughout a facility. The audio riser input provides automatic gain control (AGC) which compensates for any audio signal loss due to circuit loading or cable length, to ensure delivery of a full output signal to the speakers. For systems requiring 24-hour backup, the built-in power supply and battery charger are able to charge up to 18 AH batteries. Up to 25 ACC-25/50DA units can be connected to an ACC- 25/50 master unit. If all units are equipped with the optional second amplifier, the total wattage can be 1300 watts.
Other options include a digital message generator module providing a factory-recorded voice with field-record and playback capability (up to five distinct messages). Optional 70.7 VRMS conversion modules are available for applications requiring 70.7 VRMS speakers. Significant technological enhancements, set the ACC-25/ 50DA Series apart from other voice panels. The ACC-25/ 50DA has full supervision in both active alarm and standby conditions. Independent power feeds to each amplifier ensures that a short circuit in one amplifier will not shut down the other. Full output power (25 watts per amplifier) is generated with the optional 70.7 VRMS transformer module during low battery conditions. Additionally, modern integrated circuits, as opposed to transformer technology, amplifies audio for very low signal distortion. Suitable applications include, but are not limited to: schools, auditoriums, dormitories, theaters, restaurants, places of worship, motels/hotels, office buildings, factories, etc.
