600 Watt Expander Panel
The EVAX-600E is a complete Voice Evacuation Panels with built-in tone generators capable of operating as a stand-alone Voice Evacuation Systems with only tone and microphone amplification. It is designed to be used in conjunction with a UL listed Fire Alarm Control Panel (FACP) to provide a Listed Voice Evacuation Alarm System. The FACP provides all initiating circuitry and a signaling circuit to the EVAX-600E.
The EVAX-600E provides its own internal supervision as well as supervision for its speaker lines. Any fault is reported back to the FACP. In normal standby the supervisory circuit from the panel is connected to a matching EOLR. Should the EVAX-600E suffer an internal failure or should there be any fault on the speaker line a contact would open and the FACP would report it as an open fault for that circuit.
