3.2.9.5. Supervisory Signal Annunciation for Valves
(1) If a fire alarm system in a building is required by Sentence 3.2.4.9.(1) to have an annunciator, valves controlling water supplies in a standpipe system, other than hose valves, shall be electrically supervised in accordance with Sentence 3.2.4.10.(2).
In Plain Language
This clause addresses combined standpipe and sprinkler system designs, where a single set of risers serves both systems, setting requirements to ensure neither system's performance is compromised by sharing infrastructure.
