This article analyzes Amendment № 1 to SP
485.1311500.2020, which entered into force on
January 1, 2026, and its impact on the design of
automatic water and foam fire extinguishing sys-
tems. Key adjustments to regulatory require-
ments are discussed, including changes in sprinkler
placement, requirements for pipelines, pumping technologies is presented, including chemical,
stations, control units, and system parameters. gas, and water mist systems. Particular atten-
tion is paid to the selection criteria for water mist
systems for data centers, integration with build-
ing engineering systems, and regulatory require-
ments.
