Information About SIGA-AA50
The SIGA-AA50 is part of the Edwards Signature amplifier family, engineered for high-efficiency audio distribution in fire alarm voice evacuation systems. It connects directly to the Signature data circuit, allowing channel switching and amplifier monitoring through system software without additional control modules. Designed with two audio inputs, it accepts either line-level (1 VRMS) or amplified (25 VRMS) signals, offering flexibility in project design. Backup is supported either through dedicated amplifiers or by utilizing the onboard 1 kHz tone generator, which activates in case of input failure. The unit is housed in APS6A or APS10A enclosures and operates on 24 VDC system power or dedicated supplies.
Key Features:
- High Power Output: Delivers 50 watts at 25 VRMS or 70 VRMS.
- Dual Audio Inputs: Accepts 1 VRMS line level or 25 VRMS amplified input signals.
- Signature Data Circuit Control: Enables software-based channel switching without extra modules.
- Integrated Backup Options: Supports backup amplifier connection or automatic 1 kHz tone generator.
- Low Distortion Performance: Harmonic distortion rated at less than 5%.
- Flexible Configuration: Operates in Class B (Style Y) or Class A (Style Z) wiring.
- System Supervision: Communicates amplifier status directly to the main control panel.
- Rugged Installation: Compatible with APS6A and APS10A enclosures for secure mounting.
- UL/ULC Listed: Meets stringent standards for fire and life safety systems.
- Wide Operating Range: Functions in temperatures from 32 °F to 120 °F and up to 93% RH.
The SIGA-AA50 delivers the output power, flexibility, and supervision required for emergency communication and life safety applications.
