Title: Components of Fire Protection Systems
1Components of Fire Protection Systems
2When hearing concerning fire protection, we tend
to consider automatic Fire Sprinkler Systems and
fire alarms. However, these are simply 2 among
several parts that defend building occupants from
fire. Smoke is additionally dangerous, capable of
inflicting death by poisoning, so it should be
controlled additionally. in addition, buildings
should embody measures to assist firefighters
work a lot of effectively when fire cannot be
controlled by sprinklers alone. This article
describes the most parts of fire protection
systems, whereas indicating the NYC codification
sections with the corresponding technical
requirements. keep in mind this can be simply an
informative guide, to not be utilized in the
place of building codes for an actual project.
3Automatic Fire Sprinkler Systems. As inexplicit
by their name, automatic sprinklers reply to fire
with no want for human intervention. Movies and
television series have unfolded some inaccurate
ideas concerning fire sprinklers for instance,
there's a typical belief that sprinklers shower
indoor areas fully with the slightest sign of
smoke. In reality, fire sprinklers operate
mechanically as they reply to heat, and in
several cases one sprinkler is enough to douse a
fire. An automatic sprinkler system for an
oversized building will represent a large
investment, however repairing the injury of an
uncontrolled fire are often far more dearly-won.
additionally, occupants might suffer disabling
injuries or maybe lose their lives. There are
special applications wherever discharging water
is risky, and alternative fire-extinguishing
substances are used instead (BC 904). Some
examples are foam, CO2 and pollutant.
4Standpipes A standpipe could be a piping system
that delivers water from a main supply to hose
connections in key locations throughout a
building. Automatic dry Automatic wet Manual
dry Manual wet Semi-automatic dry Dry standpipes
are usually full of pressurized air, and water
enters the system once needed on the opposite
hand, wet standpipes are permanently full of
water. Automatic systems establish the specified
flow by themselves, whereas manual systems depend
on a local department pumper truck.
Semi-automatic systems want manual signal to
activate, however will establish the specified
flow by themselves once this happens.
5Fire Alarm Systems A fire warning device
monitors the building for the presence of fire,
creating audible and visual signals if fire is
detected. a bearing unit receives inputs from all
fire detection devices, automatic or manual, and
activates the corresponding notification systems.
additionally, fire alarms are often used to
initiate the adequate response measures once fire
is detected.
6Smoke Management Systems Humans avoid fire by
instinct, however the hazards related to smoke
don't seem to be public knowledge. Additionally,
to limiting visibility, smoke will cause
poisoning if massive enough amounts are inhaled.
Therefore, a fire protection system should even
be capable of handling smoke effectively,
avoiding its accumulation and removing it from
the building. Note that smoke movement is driven
by pressure and temperature you will not see
smoke flowing from a lower-pressure area to a
higher-pressure area, and it also tends to rise
together with hot air. Smoke management systems
are often either mechanical or passive. Note that
they complement every other Mechanical systems
use fans to manage smoke movement. Passive
systems use smoke barriers to limit is movement,
that dont consume power.
7Post-Fire Smoke Purge As previously explicit,
smoke hinders visibility and is very dangerous
once inhaled. Clearing the smoke in an
exceedingly building is very important to resume
building operation as shortly as possible once a
fire is extinguished. this can be exactly what
post-fire smoke purge systems do eliminating
smoke quickly when a fire incident. Since
post-fire smoke purge systems operate when a
fire, they're not classified as life safety
systems. however, their use is mandatory
altogether occupancy groups indicated by the code.
