Sprinkler & Deluge Systems
Overview

What Are Sprinkler and Deluge Systems?

A sprinkler system is the only fire protection that works with nobody on site, nobody awake and no decision from anyone. Heat at a head operates that head, water discharges over the fire, and it continues until somebody closes a valve. That independence is why almost every other layer of protection is built on top of it.

The important decision is the type of system, and it follows from the hazard rather than preference. Wet pipe holds water at all times and is the simplest arrangement. Pre-action keeps the pipework dry and needs detection to operate first. Deluge has open heads throughout and discharges from all of them at once over a high-hazard area.

  • Wet, pre-action and deluge Configuration is chosen from the hazard, not from a standard layout.
  • Hydraulically calculated Hazard classification sets the design density; calculation proves the supply can deliver it.
  • The whole system, not just heads Pumps, tanks, valve sets, flow switches and the alarm interface.
  • Storage designed properly Commodity classification and actual racking height drive the design.
Operation

How Sprinkler Systems Work

01

Heat operates a head

Only the heads over the fire operate, limiting water to where it is needed.

02

Water discharges

The supply delivers the design density over the area of operation.

03

Flow is signalled

A flow switch signals the fire alarm panel and summons response.

04

Control until isolated

Discharge continues, holding the fire, until the valve is closed.

Benefits

Why Choose Sprinkler Protection?

Works unattended

No detection, no power and no decision required for it to operate.

Properly calculated

Design density and area of operation follow the hazard classification.

Water only where needed

On a wet system only the heads over the fire operate.

Pre-action where it matters

Dry pipework for archives and data halls where accidental discharge is unacceptable.

Deluge for high hazard

Open-head protection for transformers, flammable liquids and process areas.

Documented and testable

Commissioned, flow tested and set up for periodic inspection.

Applications

Applications Across Critical Environments

Sprinkler protection is normally what your occupancy approval, your insurer and your fire NOC are written around.

A warehouse correctly protected when it was built can be seriously under-protected after a change of stock or an extra tier of racking, with nothing visible having changed. A review at that point is worth more than a new system later.

Configuration

Inside a Sprinkler System

  • Sprinkler heads selected by type, temperature rating and response characteristic.
  • Pipework and hangers sized from the hydraulic calculation, not from a template.
  • Valve sets and alarm valves wet, pre-action or deluge, with flow and tamper monitoring.
  • Pumps and water supply sized to deliver the design density at the most unfavourable area.
  • Fire alarm interface so flow and valve status are reported and acted on.
  • Design, commissioning and maintenance including hydraulic calculation, flow testing and periodic inspection.

  • Hazard classification and hydraulic calculation so the coverage you pay for is the coverage you get.
  • Integration with existing fire alarm systems including the cause-and-effect for any linked response.
  • Installation, testing and commissioning with the installed system proven on handover.
  • Preventive maintenance and technical support under AMC, with a documented service record.
Compliance

System Integration and Compliance

Standards and approvals

Sprinkler installations are designed to IS 15105 and to Part 4 of the National Building Code (NBC 2016), with hazard classification, design density and water supply established at design stage rather than assumed.

These systems are normally central to the fire NOC and to insurer requirements, and TAC guidance may apply where your policy references it.

We confirm component approvals against the certification held by the specific products proposed, and against your consultant's specification and insurer conditions.

Call +91 88795 33000
Do all the sprinklers go off at once?
On a wet or pre-action system, no — only the heads over the fire operate. A deluge system is the exception: it has open heads and discharges from all of them on a signal.
What is a pre-action system for?
Rooms where an accidental discharge would be unacceptable — archives, data halls and similar. The pipework stays dry until detection operates, so a damaged head alone releases nothing.
Why does hazard classification matter?
It sets the design density and the area of operation, which the hydraulic calculation then has to deliver. Get it wrong and the system can look complete while being incapable of controlling the fire.
My stock has changed — does that matter?
Very likely. Storage design depends on commodity classification and racking height, so a change of stock or an extra tier can leave a correctly designed system under-protected.
How often does it need testing?
Periodic inspection and flow testing are scheduled under AMC, with a documented record for your insurer and the fire authority.
Can it be installed in an occupied building?
Usually yes, in phases. The sequencing comes out of the site assessment and is planned around your operations.
What do you need to quote a project?
Building layout and use, storage arrangements and heights, available water supply, and whether it is a new installation or an extension.
