Information About DS-BDA
The DS-BDA is a dedicated backup amplifier designed to work in conjunction with Notifier’s DS-AMP primary audio amplifiers within fire alarm and emergency voice evacuation systems. This amplifier automatically activates when the main amplifier fails or requires redundancy support, maintaining full system functionality and intelligible voice communication. Factory-rated at 125W at 25V, the DS-BDA can be field-converted to a 70V, 100W output when paired with the DS-XF70V conversion module. Its design meets UL requirements for emergency communication systems and is compatible with Notifier’s Digital Voice Command (DVC) and related distributed audio platforms.
Key Features:
- 125W Output Power: Provides 125 watts at 25V RMS for powerful and clear audio output.
- Optional 70V Conversion: Can be converted to 70V, 100W operation using the DS-XF70V module.
- Automatic Backup Operation: Activates seamlessly when the main DS-AMP amplifier fails.
- Notifier Compatibility: Designed for DS-AMP and DVC audio systems in fire alarm networks.
- High Audio Fidelity: Maintains clear, distortion-free emergency and paging communication.
- Rugged Design: Built for reliable, continuous-duty operation in critical life-safety applications.
- UL/NFPA Compliant: Certified for use in emergency voice/alarm communication systems.
- Rack Mountable: Compact form factor allows easy installation in standard equipment racks.
The DS-BDA delivers the reliability and precision required for redundant audio amplification in emergency voice communication and fire alarm systems.
