to a piping system that is connected to a water supply through a VALVE
that is opened of a DETECTION SYSTEM installed in the same area as
the sprinklers
⩥ Dry Pipe Sprinkler System.
Answer: A sprinkler system employing automatic sprinklers that are
attached to a piping system containing air or nitrogen under pressure.
The release of the air or nitrogen,(as from the opening of a sprinkler)
results in the water pressure opening a valve known as a dry pipe valve,
resulting in the flow of water into the piping system and out of the fused
sprinklers heads.

Answer: A valve connection on a water supply system having one or
more outlets and that is used to supply hose and fire department pumps
with water.
⩥ Bulb Sprinkler.
Answer: A sprinkler operated by heat breaking a glass bulb filled with a
non-freezing liquid with diamiter that vary from 3mm for quick response
sprinklers to 5mm for standard response sprinklers.
⩥ Hose Connection.
Answer: a combination of equipment provided for connection of a hose
