В NFPA 13 и EN 12845 действительно нет, зато есть у FM Global:
FMDS 2-0
2.1.3.1.3 Mixing of Different Types of Sprinklers
Do not mix the following types of sprinklers on the same sprinkler system protecting the same hazard area unless otherwise recommended in the relevant occupancy-specific data sheet:
(a) Storage, Nonstorage, and Special Protection sprinklers
(d) Sprinklers having different K-factors
© Sprinklers having different orientation
(d) Sprinklers having different nominal temperature ratings
(e) Sprinklers having different nominal RTI values
(f) Sprinklers having different linear and/or area spacing requirements (e.g., extended-coverage and non-extended-coverage sprinklers)
Запрет не очень жёсткий.
В том же пункте есть исключения :
Exception No. 1: Install individual sprinklers having a higher temperature rating as needed based on ambient
temperature conditions (such as near unit heater outlets). Ensure the higher-temperature sprinklers are of
the same make, model, type, K-Factor, RTI, and orientation as the lower-temperature sprinklers.
Exception No. 2: An upright sprinkler may be substituted for an obstructed pendent sprinkler provided it
has the same K-factor, nominal temperature rating, nominal RTI, and recommended sprinkler spacing as the
pendent sprinkler and is compatible for the occupancy hazard.Exception No. 3: Sprinklers installed under lower ceilings are not considered ”on the same system.” See
recommendations in Section 2.1.1.4 if the lower ceiling is open-grid, or Section 2.1.1.5 if the lower ceiling is
solid.Exception No. 4: When two different occupancy hazards are adjacent to each other and are not separated
by a wall or draft curtain, extend the design of the sprinkler system protecting the higher-hazard occupancy
a minimum of 20 ft (6.0 m) in all directions beyond the perimeter of the higher-hazard occupancy area.
В разделе 2.3.3 описаны варианты совместной установки вертикальных и настенных спринклеров.
