Benefits
The primary benefit of integrating the RC9 Retard Chamber into your fire system is the drastic reduction in nuisance alarms. In many municipal areas, water pressure is not constant and can spike during off peak hours. These spikes often lift the alarm valve clapper just enough to send water toward the alarm bell. This chamber solves that problem by acting as a temporary reservoir, catching that surge and preventing the alarm from sounding until a genuine, sustained flow is detected. By using high quality stainless steel instead of cast iron, you ensure that the internal chamber remains clear of debris and oxidation, which can often lead to drainage failures in lesser products. This translates to lower maintenance costs and a higher level of trust in your safety equipment.
Usage / How to Use
The Retard Chamber is designed to be installed as part of the trim on an alarm check valve in a wet pipe sprinkler system. It is positioned in the alarm line between the valve and the mechanical alarm gong or electrical pressure switch. When the system detects a momentary pressure increase, the water enters the RC9 through the bottom port. If it is a real fire, the water continues to flow, fills the chamber, and then exits to activate the alarms. If it was just a surge, the water stops flowing and drains out through a restricted orifice, resetting the system for the next event.
