Making System Alarm Connections
The EC9535 provides a system alarm that notifies you of a malfunction, such as when a fan or

indicator that displays visual cues when the alarm is activated. Grass Valley does not provide
external indicator equipment, but does provide instructions on wiring the alarm connections.
