Gamewell-FCI 1100-0456 is the AM-50-25 amplifier: a 50 watt digital switching power amplifier with 25 VRMS audio output for the E3 Series Expandable Emergency Evacuation, Combined Fire and Mass Notification, and Broadband Voice Evacuation systems.
Each amplifier has two speaker circuits, wired Style Y (Class B) or Style Z (Class A), that share the 50 W total. The circuits are individually activated and supervised by an INI-VGX transponder voice gateway, and the amplifier can broadcast sixteen messages from its local INI-VGX.
