How They're Activated
- All fire sprinklers are fitted with glass bulbs that are filled with gases and/or liquids that expand under heat. Since
warm air rises, when a fire starts, a plume of heat is sent upwards, presumably to an elevated part of the room or facility where the fire sprinklers are installed. When these bulbs get hot enough, they break. This automatically releases a valve connected to the emergency sprinkler system, prompting it to go off. According to Fire Sprinklers UK, the glass bulbs are typically set to break at a certain temperature, usually around 68 degrees Celsius.

Other Reasons: Overheating
- Fire sprinklers don't know the difference between the heat from a fire or the heat from another object. They're simply triggered to activate when they detect a predetermined buildup of heat. According to the National Fire Sprinkler Association, this means that they could potentially be triggered inadvertently if heat-emitting objects like construction lighting, unit heaters and television cameras are placed in close proximity to sprinkler heads. Skylights have also been known to trigger sprinklers, as the shining sun can produce enough heat for activation.
Other Reasons: Sabotage
- Other reasons as to why fire sprinklers discharge or leak include freezing pipes, pipe corrosion or manufacturing defects. One cause of fire sprinkler activation, notably in the case where there's no actual fire, is sabotage, states the National Fire Sprinkler Association. This is when a person purposefully starts a fire in a home or business or activates the fire sprinkler system in order to recoup insurance money from the damage that is endured. However, this is illegal.
