Notifier ACT-25 Audio Coupling Transformer (NEW)
Notifier ACT-25 Audio Coupling Transformer – Scalable Audio Isolation for Fire Alarm and Mass Notification Systems
The Notifier ACT-25 is a UL 864 9th Edition certified audio coupling transformer designed to support high-performance audio distribution in large-scale fire alarm and emergency communication systems. Ideal for integration with DAA, DVC, and AA-series amplifiers, the ACT-25 converts high-level 25VRMS signals into low-level audio, providing electrical isolation and common mode noise rejection (CMNR) for clean, reliable signal transmission.
Perfect for multi-amplifier configurations, the ACT-25 enables audio signals to feed up to 40 analog amplifiers with wiring runs up to 200 feet. Whether deployed in riser mode with digital audio amplifiers or in combination with AA-30, AA-100, or AA-120 systems, it ensures seamless, interference-free communication in critical environments.
