APPLICATION:
Control valves for automatic sprinkler systems and
systems serving other equipment where a water supply serves both the automatic
sprinkler system and the system serving other equipment.
INTENT:
To limit the probability that the sprinkler system will
be shut off during maintenance or servicing of the other systems, which could
lead to the sprinkler system not operating in a fire situation, which could
lead to the fire not being suppressed or controlled, which could lead to the
spread of fire to other parts of the building, which could lead to harm to
persons.
