FFA-RC-1 Retard Chamber

Description

RC-1 Retard Chamber – Alarm Delay Device for Fire Sprinkler Systems

The RC-1 Retard Chamber is a specialized component designed for use with alarm check valve assemblies in wet pipe fire sprinkler systems. It provides a time delay function that helps prevent false alarms caused by temporary pressure fluctuations, water surges, or momentary system pressure variations.

Installed within the alarm trim line of compatible alarm check valves, the RC-1 Retard Chamber allows stable system operation by controlling the timing of water flow to the alarm device. Its durable construction and reliable performance make it suitable for commercial, industrial, and building fire protection applications.

Manufactured from corrosion-resistant materials, the RC-1 is designed for dependable service in fire protection water systems and supports effective integration with mechanical alarm devices and sprinkler system components.
