Notifier DAA-5025F Digital Audio Amplifiers w/ PS

The DAA Digital Audio Amplifiers are multi-featured amplifiers with digital audio functionality. They are designed for a networked or non-networked environment with the XLS-DVC Digital Voice Command. DAA models are compatible with other types of DAL devices (e.g. DAA2, DAX) on a wire, fiber, or mixed wire/fiber digital audio loop. A DS-RFM (for multi-mode DAAs) or DS-SFM (for single-mode DAAs) is required for a fiber DAA used on a DAL with other types of DAL devices.

NOTE: The term DAA is used in this manual to refer to all the model versions listed in the bullets below this note. Individualpart numbers are used to distinguish features or functions that differ.

Features
The DAA audio amplifiers have the following features:
• 50W total output power at 25VRMS (all DAA-5025 model versions) or 70 VRMS (all DAA-5070 model versions).
• 75W total output power at 25VRMS (all DAA-7525 model versions).
• Two Class A connections for high-level audio output, or alternately, four Class B connections, or four Class A outputs when used with the DCADC DAA2 Class A Daughter Card, which dynamically share the 50W output capability.
• Audio output activation via network control-by-event equations resident within the XLS-DVC.
• Isolated alarm bus input, to be used for backup activation of alarm messages when normal digital communication is lost.
• Amplifies one channel of digital audio and distributes it on up to four outputs (50W maximum).
• Auxiliary input for 12VP-P analog low-level AMG-1 type audio sources.
• Auxiliary input for 1.6Vp-p max. for each circuit when both AUXA L and AUXA R are used, or 3.2Vp-p max. for one when only one circuit (AUXA L or AUXR) is used, to be used for background music input, an interface with a telephone paging source, or other compatible audio sources. Includes user audio level adjustment feature.
• Uploads and downloads via the XLS-DVC.
• Up to 106 seconds of Backup Digital message storage (Emergency tone, Non-Emergency tone, and FFT busy tone) for use in the event of communication loss- either standard quality or high quality, from the VeriFire Tools message library or created by the installer.
• Battery charger (50 watt DAAs only) and power supply capable of supporting up to 55AH batteries.
• Relay contacts that will activate on a trouble condition.
• Backup amplifier function.
• Programmable through VeriFire Tools.
• Meets UL requirements for 800 Hz to 2.8 KHz bandwidth.
Meets ULC requirements for 400 Hz to 4 KHz bandwidth.
