Sprinkler & Hydrant Systems

Sprinkler and Fire Hydrant Systems — Design, Supply and Installation

Automatic sprinkler and fire hydrant systems form the active suppression layer of a building fire safety strategy, working alongside passive fire doors and compartmentation to detect, suppress, and contain fires before they grow to life-threatening proportions. NBC 2016 Part IV mandates automatic sprinklers in buildings above 15 metres in most occupancy categories, and fire hydrant systems for all buildings above a specified height or floor area.

Automatic Sprinkler Systems

IFES designs and installs wet pipe sprinkler systems (water-filled pipework, immediate response) and dry pipe systems (nitrogen or air-pressurised pipework for unheated spaces) as per NBC 2016 Part IV and IS:15105. Each sprinkler head activates independently at a pre-set temperature (68°C for standard response, 93°C for intermediate, 141°C for high temperature), discharging water directly onto the fire source. Statistical data consistently shows that 96% of fires are controlled by four or fewer sprinkler heads — making sprinklers the most cost-effective active fire suppression measure available.

System components: wet alarm valve assembly, sprinkler heads (pendant, upright, sidewall — concealed or exposed), flow switches, pressure gauges, inspectors test valves, main control valve, and complete MS or CPVC pipe network. Designed to IS:15105 hydraulic calculation methodology with zoned isolation valves for maintenance flexibility.

Fire Hydrant Systems

IFES designs and installs complete fire hydrant systems including underground ring main (looped or dead-end as per NBC requirements), terrace/overhead ring main, fire water storage tanks (RCC or MS, sized to NBC Part IV requirements), electric fire pump, diesel engine-driven standby pump, and electric jockey pump for pressure maintenance. Above-ground pipework with landing valves at each floor level, 63 mm and 75 mm hose connections, fire brigade inlets, and pressure-reducing valves where system pressure exceeds 6.9 bar.

NOC Documentation

IFES provides complete statutory documentation for fire NOC approval: hydraulic calculations, isometric drawings, equipment submittals, pump performance curves, and commissioning test reports — all formatted to local fire authority requirements.
