TB203 (2009 draft) - Care and Maintenance of Sprinkler Systems

This Technical Bulletin gives details of water supplies for life safety sprinkler systems and provides an interpretation of how the guidance given in Approved Document B (ADB) measures may be complied with whilst fully complying with the LPC Rules for automatic sprinkler installations. Other ADB compliant interpretations may not comply with the LPC Rules and may not be suitable for property insurance purposes.

This Technical Bulletin specifies the types of alarm valve which may be used and the design of installation control valves. Measures are specified to ensure the continuous supply of water to sprinkler installations whilst alarm valve maintenance is undertaken. Alternate alarm valves have been excluded on the grounds of causing accelerated corrosion to sprinkler pipework.

Isometric graph paper read for you to print out on to A4 paper. Useful for sketching out and node numbering complicated sections of pipe.
