Information About AM-50-70
The AM-50-70 is part of the Gamewell-FCI AM-50 Series, engineered to provide high-quality voice evacuation and mass notification audio. With digital switching technology, it delivers 50 watts of efficient, clear audio power at 70.7V RMS across two supervised speaker circuits. The amplifier can broadcast up to 16 messages generated by the INI-VGX Voice Gateway and supports intelligible live voice paging, including compliance with UL 464 low-frequency 520 Hz requirements when used with approved speakers. Multiple AM-50 amplifiers can be combined under one INI-VGX, making it a flexible solution for expanding voice evacuation systems.
Key Features:
- 50W supervised audio output: Provides 50 watts of digital power across two Class A/B speaker circuits for reliable emergency communication.
- 70.7V RMS operation: Optimized for distributed speaker systems requiring constant voltage audio distribution.
- Dual speaker circuits: Two integral circuits can be wired Style Y (Class B) or Style Z (Class A), providing installation flexibility.
- Voice messaging support: Capable of broadcasting up to 16 prerecorded messages from the INI-VGX Voice Gateway.
- Live paging capability: Supports high-quality, intelligible live voice paging for real-time announcements.
- Multi-amplifier integration: Up to four AM-50 amplifiers with the same output voltage can be controlled by a single INI-VGX module.
- Flexible wiring support: Accommodates up to 12 AWG twisted-pair shielded wire for secure and code-compliant installation.
- Low-frequency compliance: Meets UL 464 standards for 520 Hz low-frequency tone when used with compatible System Sensor speakers.
- Compact and lightweight: At just 2 lbs and 14 × 11 × 6 in, it provides powerful output in a small form factor.
- Standards certified: Listed under UL 864 (9th Edition) and UL 2572 for mass notification, ensuring full regulatory compliance.
The AM-50-70 delivers the reliability and precision required for voice evacuation, paging, and mass notification in commercial fire alarm and life safety systems.
