How a fire sprinkler system works
A fire sprinkler system is a type of fire suppression system. It uses pipes filled with water under pressure, installed behind walls and ceilings. As a fire raises the surrounding temperature, the liquid inside a sprinkler's sealed glass bulb expands. The bulb breaks, and water sprays over the fire to help control it. Each sprinkler protects the area below it, and only the sprinklers near the fire open.
Why automatic sprinklers matter to a building owner
Automatic sprinklers respond quickly to heat. They help control flames, reduce heat and limit the toxic smoke produced by a fire. Without sprinkler protection, a fire can grow and spread to other areas, and heat and toxic gases can cause serious property damage and loss of life. A sprinkler system also gives the fire brigade time, since the fire is held in check while they arrive.
Types of sprinkler heads
The right head depends on what you store and how high the ceiling is. We supply these types:
- Quick response
- Standard response
- Control Mode Specific Application (CMSA)
- Residential
- Early Suppression Fast Response (ESFR)
Where fire sprinklers are used
Fire sprinklers are used in residential, commercial and industrial buildings:
- Buildings and apartments
- Offices and commercial areas
- Hospitals
- Shopping malls
- Industrial premises and warehouses
Fire NOC requirements
Local government Fire NOC requirements apply to premises such as function halls, cinema halls, hotels, hospitals, schools, high-rise buildings and commercial complexes. Essatech undertakes sprinkler installation but does not issue Fire NOCs. The fire department issues the NOC. We prepare the system drawings and papers it asks for, and our Fire NOC guidance explains the steps.
What you get from Essatech
We supply sprinkler heads, system design and installation, including automatic sprinkler systems, as a complete job:
- A free site survey and a sprinkler layout from your drawings
- Design of pipework, heads and the water supply
- Supply and installation of heads, pipes, valves and the alarm connection
- Pressure testing and a flow test before handover
- Maintenance visits and yearly checks, if you want them
The water supply behind it
Sprinklers are only as good as their water supply. The system needs a tank of the right size and a fire pump that delivers the pressure the design needs. If your building also needs hydrants, the same pumps can supply a fire hydrant system. We size the whole chain together, so you do not find out at handover that the pump is too small.
For builders, architects, MEP consultants, corporates, industries, hospitals and defence
Builders and architects should coordinate sprinkler heads with the ceiling grid, lights and air conditioning, and leave riser and tank space in the design. Industries and warehouses choose head types for storage height and hazard, and commercial building owners for malls and offices. Hospital owners use sprinklers in wards, corridors and stores, where quick control of a fire gives staff time to move patients. MEP consultants can send the hydraulic design and ceiling drawings and we price the heads, pipework and pump set. Corporates protect offices and campuses. Defence sites, including Navy and Army stores, hangars and accommodation, use sprinklers, and we quote within their security and vendor rules.
What decides the cost
Sprinkler prices vary with the building, and quotes can leave items out. Ask what is included, and compare these points:
- Floor area, ceiling height and the hazard of what is stored
- New building or retrofit, since retrofit means working around finished ceilings
- Pump set, tank and pipework to the plant room
- Alarm connection, ceiling repair and approval support
