Fire Alarm

The RD Retard Chamber is used with the Alarm Valve Trim when variable pressure is anticipated in the system. It is a holding tank to prevent the sounding of the sprinkler alarm during a water pressure surge but will permit the sounding of the alarm on a sustained flow. The retarding chamber is connected to the alarm port of the alarm valve through the restriction nozzle. The retarding chamber is part of UL Listed Alarm Valve Trim. The retarding chamber is made of stainless steel material

System Sensor EPS10 Series switches are designed for use in wet, dry, deluge, and pre-action automatic sprinkler systems to indicate a discharge from a sprinkler.
