Not just any heat source will trigger a sprinkler system to activate.
Sprinkler system working principle.
Principle of operation under normal conditions water discharged from an automatic sprinkler is restrained by a cap or valve.
When the air is hot enough and reaches a sprinkler head it triggers a chain reaction.
Sprinkler heads operate individually.
The sprinkler heads must detect a high enough temperature usually between 135 and 165 degrees fahrenheit 57 to 74 celsius.
Note the red liquid alcohol in the glass bulb.
When a blaze ignites the air directly above it heats rapidly.
The installation is pressurised with the alarm valve secured in the open position.
A fire sprinkler system is an active fire protection method consisting of a water supply system providing adequate pressure and flowrate to a water distribution piping system onto which fire sprinklers are connected.
A sprinkler system is a network of pipes running through the ceiling of a building holding water under pressure.
Each sprinkler is nothing but a faucet or tap as they call it in some countries a hole in the pipe through which water can escape into the building below.
This hot air rises and spreads along the ceiling.
