Sprinkler systems are not just about placing heads on the ceiling.

Spacing and coverage decide how effective the system is.

A common assumption is:

"Just follow a fixed distance and install."

But in reality, it's not that simple.

Basic idea:

Each sprinkler is designed to cover a specific area.

Typical practice (standard conditions):

Around 12-15 m² per sprinkler

Spacing depends on hazard classification

Distance from wall is also limited

But on site, spacing changes due to:

Ceiling height

Obstructions like beams or ducts

Type of hazard (light / ordinary / high)

One thing I've seen:

Sprinkler type (pendent, upright, sidewall)

Wrong spacing

poor coverage

ineffective fire

control

* More sprinklers doesn't mean better protection

* Proper layout does

Always remember:

Design is not about placing heads.

It's about ensuring coverage where it matters.
