Fire Fighting Systems | Fire Protection Systems
We deal in Fire Fighting Systems like Water Hydrant Fire Fighting System, Water / Foam
Monitor Fire Fighting Systems, Water / Foam Sprinkler Fire Fighting System, Water / Foam
Spray Fire Fighting System, Water / Foam Hose Reel Fire Fighting System, Fire Detection Fire
Fighting System and Fire Suppression / Extinguishing Fire Fighting Systems. We specialize in
Designing, Installation and Maintenance of Fire Fighting Systems. We follow the standards for
the Designing, Installation and Maintenance of Fire Fighting Systems. We have qualified team
for the installation of Fire Fighting System.

Water Hydrant Fire Fighting System
Water Hydrant Fire Fighting System consist of hydrants
attached to same pipeline, the other end of the pipeline
is attached to the pumps and water supply tank. The
Fire Fighting Hydrant line is close loop pipe system to
maintain the pressure in the water hydrant fire fighting
system. In Water Hydrant Fire Fighting System
hydraulic calculations are done according to NFPA
Standards. Fire fighting piping may be underground
and above ground. MS pipe is use for above ground Fire
Fighting Piping and HDPE piping is use for
underground Fire Fighting Hydrant line. Fire hose
cabinet with two hoses is installed near each Fire
Hydrant to use fire hoses at the time of fire hazard
emergency.
Water / Foam Monitors Fire Fighting System
Water / Foam Monitor Fire Fighting System works
same as Water Hydrant Fire Fighting System instead of
hydrants fire monitors are installed on the fire fighting
pipeline. Fire monitor fire fighting systems are installed
on open type hazards. Fire monitors has high velocity
nozzles attach to the end of the pipe which laminate the
water steam and project it at a long distance more than
100 feet. In foam type monitor fire fighting system each

monitor is separately provided with foam container or
foam is injected into the fire fighting system pipeline via
foam proportioner by bladder type system or any
pressurize system. We installed these Fire Fighting
Systems according to NFPA standards.
Water / Foam Sprinklers Fire Fighting System
Water / Foam Sprinkler Fire Fighting System consists
of fire sprinklers attached to the fire fighting pipeline
and are installed at the top on ceiling or on the wall.
The water sprinkler fire fighting system may be wet type
of dry type depending upon the temperature and
distance of fire fighting water source from the hazard
and nature of fire hazard. In dry type sprinkler dry air
or nitrogen is used. The Water / Foam Sprinkler fire
fighting system is controlled by the alarm check valves.
The fire sprinkler is consists of bulb and deflector. Bulb
is filled with heat sensitive fluid. When the temperature
of the surrounding increase the liquid in the bulb
expand, ruptured the bulb glass, the fire sprinkler
orifice is opened and water sprinkler fire fighting
system is activated. The fire sprinklers have deflector
type head to project the water stream at particular
position. In Foam sprinkler fire fighting system foam is
injected into the fire fighting pipeline with foam
proportioner and open type fire fighting sprinklers are
installed. The whole fire fighting system is control by
deluge valve via any detection system
Water / Foam Spray Fire Fighting System
Water / Foam Spray Fire Fighting System is the same as
the sprinkler fire fighting systems except instead of bulb
fire sprinklers open type high velocity or medium
velocity fire spray nozzles and deluge system is installed
instead of fire alarm check valve. Water spray fire
fighting system is activated mechanically by a fire
sprinkler systems that is installed with the same pattern

as nozzles or electrically by solenoid valve from control
panel with sensing devices such as heat detector and
smoke detector that detect the fire and pass signal to
control panel .In foam spray fire fighting system foam is
injected into the fire fighting system after the activation
of fire fighting system (deluge valve) by the foam
proportioner that make the 3%, 6 % or 9% foam
solution according to adjustments. We installed both
foam based or water based fire fighting systems
according to requirement of hazard by following NFPA.
Water / Foam Hose Reel Fire Fighting System
Water / Foam Hose Reels Fire Fighting System consist of fire
hose reels that are installed on the inside of the building in
the form of reels in a cabinets. Fire hose reel cabinets are
fitted with the fire hose reel or fire hose rack. The water
supply to these hoses is from pump room or main fire
fighting hydrant line. The hoses have different kind of
nozzles at its ends for different type of fire hazards. The fire
hoses are made of different material and sizes that are
installed according to the nature of hazards. Fire hose reels
are both water base and foam base. In foam base hose reels
fire fighting system the foam tank is installed under the fire
hose cabinet and the mixing of the foam is by foam eductor
installed
after
the
landing
valve.
The
percentage
concentration of the foam is depends upon the fire hazard
type.
Fire Extinguishing Fire Fighting System
The C02, Argon, HFCs, FM200 & high pressure water mist
are used in these kind of fire fighting systems, the
extinguishing agent is kept in cylinders at high pressure. The
fire extinguishing fire fighting system is controlled by pilot
cylinder or control valve by fire control panel via heat
detectors or smoke detector depending upon the nature of
hazard area. The fire fighting system area calculations are
done according to NFPA standards. Fire alarm & flashers are
also installed in combination with extinguishing fire fighting
system to evacuate the area to be protected to alert the
occupants before the activation of the fire fighting system.

Fire Detection & Alarm System
The Fire detection & Alarm Systems are conventional and
addressable system. The detection fire fighting systems are
divided into zones depending upon the nature of fire or
hazard area. The detection fire fighting systems also contain
manual push buttons sounders and flashers that activated a
few second before the system to alert the occupants from fire.
The conventional fire fighting system are installed with less
number of inputs and outputs devices but addressable are
multitask fire fighting systems that also merged with other
systems to control the butterfly valves, Solenoid valves and
pressure switches to activate the fire fighting systems like
foam system activation. The heat detectors, smoke detectors
and flame detectors are the fire detection devices that are
installed on these fire fighting systems that send input fire
signal to main control panel to activate the sounder & flasher
and also alert the fire safety person.
