Armstrong International D14826 Indicator

The Armstrong International D14826 is a critical electrical proof of closure indicator (model CPI-400) engineered for integration with high gas pressure switches in industrial Flo-Direct fuel trains. This OEM electrical switch provides essential safety verification by offering positive confirmation of switch closure, preventing hazardous system faults and ensuring the efficient operation of Armstrong International HVAC equipment. Built to withstand demanding thermal exchange environments, the D14826 indicator typically operates at 120VAC with a robust construction rated for an ambient temperature range of -40°F to 150°F. As a genuine replacement part, it maintains the precise safety monitoring requirements of Flo-Direct gas-fired water heaters, including models like the AFD-1000 through AFD-15000. Utilizing an authentic Armstrong D14826 ensures seamless switch status monitoring, supporting the overall reliability and performance of your high-performance gas management system.

Key Benefits:

• Ensures positive verification of valve closure for improved industrial safety.
• Designed specifically for compatibility with high gas pressure switches on Armstrong fuel trains.
• Rugged construction and reliable electrical monitoring reduce unplanned system downtime.
• Facilitates seamless installation and technical integration with DIN Connector D210319.
• Protects system integrity by accurately reporting switch status to the electrical control panel.

Common Questions:

What does a proof of closure indicator do in an HVAC system?
A proof of closure indicator, like the Armstrong D14826, provides a clear electrical signal to the controller confirming that a safety switch or valve has fully closed before the system proceeds with the next step of the firing sequence.

Is the D14826 compatible with all Flo-Direct water heaters?
Yes, this CPI-400 electrical indicator is the standard OEM part for the high gas pressure switches across the Flo-Direct AFD series fuel trains, from smaller units to high-capacity industrial models.

Can I replace a visual indicator with the D14826 electrical indicator?
The D14826 is an electrical indicator designed for automated system monitoring. While visual indicators provide local status, this part is necessary for electrical interlock and remote safety verification in the burner control circuit.
