- A fire sprinkler or sprinkler head is the component of a fire sprinkler system that discharges water when the effects of a fire have been detected, such as when a predetermined temperature has been exceeded.
- In buildings protected by properly designed and maintained fire sprinklers, over 99% of fires were controlled by fire sprinklers alone.
- The number of sprinklers that operate is limited to only those near the fire, thereby maximizing the available water pressure over the point of fire origin.
- The time it takes before a bulb breaks is dependent on the temperature. Below the design temperature, it does not break, and above the design temperature, it breaks, taking less time to break as temperature increases above the design threshold.
- The sensitivity of a sprinkler can be negatively affected if the thermal element has been painted.
