COMPONENTS OF FIRE SYSTEMS
FIRE HYDRANT SYSTEM
1. Diesel Engine Driven Standby Pump
The standby diesel engine driven pump set is proposed so that in case of power failure during emergency, this pump set can be operated.
The pump set would be driven by a diesel engine which should develop at least 20% more power than that required by the pump over the entire range of
operation and not restricting to 150% of the duty point.
The pump set should be erected on anti-vibration mounting and not grouted.
For other details refer the Data Sheet Doc. No. OBS/DEDSP/01.
2. Electric Motor Driven Jockey Pump
The jockey pump set is utilized to maintain the system pressure over a range.
Due to small leakages either through the gland of the valves etc., the system pressure falls and once the system pressure falls below a certain level, the jockey pump starts and stop when the pressure loss is compensated.
The pump set would be driven by a electrically operated motor which should develop at least 15% more power than that required by the pump over
the entire range of operation and not restricting to 150% of the duty point.
The pump set should be erected on anti-vibration mounting and not grouted.
For other details refer the Data Sheet Doc. No. OBS/JP/01.
3. Electric Motor Driven Fire Pump
In case power is available during emergency or if generator power is available as a dedicated supply to run it.
The pump set would be driven by a electrically operated motor which should develop at least 15% more power than that required by the pump over the entire range of operation and not restricting to 150% of the duty point.
The pump set should be erected on anti-vibration mounting and not grouted.
For other details refer the Data Sheet Doc. No. OBS/EMDP/01.
4. Fire Brigade Inlet (3 – Way)
The Fire Brigade Connector is used by fire brigade authorities to pump in water from external sources so that water can be pumped in into the system at a
requisite pressure to enable fire fighting operations.
The connectors should be S.S.A C.I. Gate Valve along with a C.I. Non-Return Valve of dia. 150 mm will have to be installed below the Fire Brigade Connector, so that line pressure is not reduced due to leakages.
For other details refer the Data Sheet Doc. No. OBS/FBI/01.
5. Flow Switch
The Flow Switch is used to notice any movement of water / fluid in the pipeline.
The Flow Switch sends the signal to the annunciation panel whenever it senses a movement of water fluid in the pipeline.

It should be ISI marked.
For other details refer the Data Sheet Doc. No. OBS/FEX/CO2/01.
8. Mechanical Foam type Fire Extinguisher
The Mechanical Foam type Fire Extinguisher is used to extinguish the small fire over the affected zone.
This type of extinguisher is suitable to use for fire in paper, wood, clothes and plastics only.
It should be ISI marked.
For other details refer to PAGE 2 of the Data Sheet Doc. No. OBS/MFEX/02.
9. DCP type Fire Extinguisher
The DCP type Fire Extinguisher is used to extinguish the small fire over the affected zone.
This type of extinguisher is suitable to use for fire in petrol, oil, paints, thinner, spirits, flammable gases, electrical fire, magnesium, sodium, potassium, electricity and electrical appliances.
It should be ISI marked.
For other details refer to PAGE 3 of the Data Sheet Doc. No. OBS/DCPFEX/03.
10. Water Co2 type Fire Extinguisher
The Water Co2 type Fire Extinguisher is used to extinguish the small fire over the affected zone.
This type of extinguisher is suitable to use for fire in paper, wood, clothes and plastics etc.
It should be ISI marked.
For other details refer to PAGE 4 of the Data Sheet Doc. No. OBS/WCO2/FEX/04.
11. Hose Reel Drum Assembly
The Hose Reel is used to extinguish small fires and aptly called as first aid equipment.
After noticing a fire anyone can draw the rubber hose and get it next to the fire and open the shut off nozzle to extinguish a small fire. 30 M of ISI marked
rubber hose should be supplied. The Drum should be powder coated. The nozzle should be ABS plastic.
For other details refer the Data Sheet Doc. No. OBS/HRDA/01.
12. Branch Pipe with nozzle
It is attached / coupled to the hose coupling to direct the water jet to the seat of fire. It should be made of S.S.
For other details refer the Data Sheet Doc. No. OBS/BRPN/01.
13. Hose Box, RRL Hose & Hose Coupling
Hose box is used to house the hoses (2nos.) and branch pipe with nozzle.
Hose pipe and nozzle are used to connect the hydrant valve so that it can be used to direct the water to the seat of fire.
The hoses should be RRL (636, Type II) . The couplings should be S.S.
For other details refer the Data Sheet Doc. No. OBS/HBC/01.
14. Pressure Switch
This is used to sense the pressure in the system. It should be INDFOSS /Dan Foss make. The model should be RT – 116.
For other details refer the Data Sheet Doc. No. OBS/PW/01.
15. Y- Strainer
This is used to remove if any higher sized. Particles are anticipated in suction line.
