FREQUENTLY ASKED QUESTIONS
Technical guidance regarding Indian Standards (IS), testing pressure norms, and dispatch schedules.
Q1.What is IS 5290 and why is it mandatory for fire hydrant valves?
IS 5290:1993 is the Bureau of Indian Standards (BIS) specification governing Landing Valves for fire protection. It mandates strict materials of construction (Gunmetal LTB2 or Stainless Steel CF8/CF8M), hydrostatic test pressure of 21 kgf/cm², seat tightness of 14 kgf/cm², and a minimum water flow rate of 900 LPM at 7 kgf/cm². Compliance is mandatory under the National Building Code (NBC) for building occupancy clearance.
Q2.What is the difference between RRL Type A and CP Type B fire hoses under IS 636?
IS 636 Type A (Reinforced Rubber Lined - RRL) is a completely non-percolating hose where zero water weeps through the jacket, delivering maximum hydraulic velocity for commercial and industrial hydrants. Type B (Controlled Percolating - CP) allows a microscopic film of water to weep through the jacket to protect the hose from burning embers and radiant heat during forest and direct structural fires.
Q3.Are Tulsi Fires products approved by DRDO, NTPC, and Indian Oil?
Yes. Tulsi Fires (M/s. Neha Tech Industries) supplies certified fire safety equipment to major public sector undertakings (PSUs) and defense institutions across India, including DRDO, NTPC, Indian Oil Corporation, BHEL, BPCL, and Power Grid Corporation.
Q4.What fire extinguishing agent is recommended for Server Rooms and Data Centers?
CO2 (Carbon Dioxide) and Clean Agent extinguishers conforming to IS 15683 are strongly recommended. Unlike dry chemical powder, CO2 leaves zero residue and is non-conductive, protecting sensitive circuit boards, hard drives, and electrical panels from secondary corrosive damage.
Q5.What is the delivery timeline for bulk industrial fire hydrant equipment orders?
Standard catalog items (landing valves, instantaneous couplings, 15m/30m RRL hoses, hose reel drums, and portable extinguishers) are maintained in high ready-stock inventory at our New Delhi facility and can be dispatched within 24 to 48 hours across India. Custom-engineered monitors and specialized flanged valves ship within 5 to 7 business days.
Q6.Does Tulsi Fires provide BIS / ISI test certificates with dispatches?
Yes. Every consignment from Tulsi Fires is accompanied by manufacturer test certificates, hydrostatic batch inspection reports, and BIS ISI certification verification documentation.
