Because the water is always in the piping, fire sprinklers are always “on call.” If fire breaks out, the air temperature above the fire rises and the sprinkler activates when the air temperature gets high enough.

Can sprinklers accidentally activate?
Accidental discharges of fire sprinklers typically occur due to inadvertent overheating, freezing, mechanical damage, corrosion, manufacturing or installation defect.
What causes fire alarm sprinklers to go off?
What DOES Set Off Fire Sprinklers? Fire sprinkler systems are actually quite sophisticated, and are designed to be heat sensitive so that sprinklers only activate when the temperatures rise to fire-induced temps, usually somewhere between 155 to 165 degrees Fahrenheit.
What happens when fire sprinkler goes off?
In the event of a fire, the heat will activate the sprinkler, which causes the air pressure to drop in the pipes. Once the pressure drops, the dry pipe valve opens up and releases the water, which will only flow out of the activated sprinklers.

What triggers a fire sprinkler?
The most common type of trigger is a glass ampule filled with a glycerin-based liquid that expands when heated. 155º As soon as the trigger mechanism is heated to the required temperature, it trips and the water is released.
What causes a sprinkler to go off?
Fire sprinklers work because high heat triggers the sprinkler system. When a blaze ignites, the air directly above it heats rapidly. This hot air rises and spreads along the ceiling. When the air is hot enough and reaches a sprinkler head, it triggers a chain reaction.
Is there a chance for a fire sprinkler system to go off?
A fire sprinkler, as this recent viral video shows, is an effective fire safety tool—but it can be unintentionally discharged when it is accidentally set off by friendly fire or a fire sprinkler head is struck or sheared off by a person or equipment.
Setting Off Fire Sprinklers With Fire Alarm Activation
Why does my sprinkler alarm keep going off?
With most fire sprinkler false alarms, water was flowing. The small jockey pump used to keep pressure in a sprinkler system, when there's no fire, isn't supervised. If it's tuned on for a long enough time, the waterflow switch could sense an alarm. When there's a fire, the main fire pump keeps the water flowing.
What happens if you accidentally hit a fire sprinkler?
Unfortunately, any impact to the sprinkler can disrupt the setup, resulting in damage to and separation of parts. A large enough force can immediately open a sprinkler, but even a smaller impact can cause the sprinkler head to break up over time.

Can you accidentally set off a sprinkler?
A fire sprinkler, as this recent viral video shows, is an effective fire safety tool—but it can be unintentionally discharged when it is accidentally set off by friendly fire or a fire sprinkler head is struck or sheared off by a person or equipment.
What triggers automatic sprinklers?
When the air around a sprinkler reaches a certain temperature, the liquid inside the bulb expands until the pressure causes the glass to break. In wet sprinkler systems, pressurized water in the pipes then forces out the plug and flows over a deflector plate that sprays it onto the fire in a carefully designed pattern.
