contains an an antifreeze solution and is connected to a water supply. The antifreeze solution is
discharged, followed by water immediately upon operation of sprinklers opened by heat from a fire
Automatic Ball Drip

Control Mode Specific Application (CMSA) Sprinklers
Designed to control a fire until its original fuel source is depleted or until fire-fighting activities can
commence. A fire is controlled by cooling the ceiling-level air temperatures, reducing the fire's rate
of heat release and pre-wetting adjacent combustibles.

specifications.
Deficiencies
Includes Critical & Non Critical
Critical Deficiency
A deficiency that, if not corrected, can have an effect on the performance of the fire protection
system.

A water supply control valve intended to be operate by actuation of an automatic detection system
that is installed in the same area as the discharge devices.
Deluge Sprinkler System
A sprinkler system employing open sprinklers that are attached to a piping system that is connected
to a water supply through a valve that is opened by the operation of a detection system installed in
the same areas as the sprinklers. When this valve opens, water flows into the piping system and
discharges from all sprinklers attached.
