Need for Periodic Inspection/Maintenance:

  This product must 

be tested periodically in compliance with local codes, but at least 

once per year or more as service conditions warrant. If installed on 

a fire suppression system, all mechanical checks, such as alarms 

and backflow preventers, should be flow tested and inspected in 

accordance with NFPA 13 and/or NFPA 25. All products must be 

retested once maintenance has been performed. Corrosive water 

conditions, and/or unauthorized adjustments or repair could render 

the product ineffective for the service intended. Regular checking 

and cleaning of the product’s internal components helps assure 

maximum life and proper product function.

Installation, Maintenance, and Repair Manual

Series 4000SS

Reduced Pressure Zone Assemblies
8" – 12"

Series 4000SS sizes 8" to 10" include a flood sensor that detects 

excessive relief valve discharges and triggers notification of potential 

flood events. 
 

NOTICE

An add-on connection kit is required to activate the flood sensor. 

Without the connection kit, the flood sensor is a passive component 

and will not communicate with any other device. (A retrofit sensor 

connection kit is also available for existing installations. See “Add-on 

and Retrofit Sensor Connection Kits,” for ordering details.)

NOTICE

Use of the flood sensor does not replace the need to comply with all 

required instructions, codes, and regulations related to installation, 

operation, and maintenance of this product, including the need to 

provide proper drainage in the event of a discharge.
