Many people think fire sprinklers instantly spray water the second there’s smoke… but concealed fire sprinklers actually work in stages.
First, the cover plate drops away once it reaches a certain temperature.
Then, as the heat continues to rise, the sprinkler head behind it activates and releases water.
It’s a controlled response designed to react to real fire conditions, not small everyday things like steam or burnt toast.
That short delay between the cover plate falling and the sprinkler activating is all part of how concealed systems are engineered to work properly when they’re genuinely needed 🔥
