The VIQUA Arros dry-contact provides a reliable way to integrate your UV system with external devices for enhanced monitoring. This feature utilizes an external port on the controller to deliver an open/closed relay signal, indicating whether a critical alarm is present on the UV system. By enabling seamless communication with other components, it ensures appropriate responses to critical alarms. Key applications include: Automatic Water Shutoff – Connect to a junction box and solenoid valve to stop water flow during a power outage or critical UV system alarm, preventing unsafe water from entering the supply. Enhanced Visibility for Critical Alarms – Trigger an external indicator light or buzzer in a more visible location than the UV system, ensuring critical alarms are noticed promptly. Remote Monitoring Integration – Link to external monitoring systems for real-time alarm updates and improved oversight of water treatment operations. The Dry Compact option is available on the Arros 9, Arros 15, and Arros 22.
