Sprinklers are an electrical-based fire extinguishing system. This system consists of three major parts which are: a system to detect fire, a system to activate the extinguisher and a fire extinguisher agent which actually extinguishes the fire.
The detection system is usually a head-mounted on ceilings or walls so that it can detect fire. It usually contains a glass bulb which encloses a heat sensitive element. In the case of a fire breakout, the heat-sensitive element of the bulb expands due to rising in temperature and leads to the breakage of a glass bulb on exceeding a threshold temperature.
When the glass bulb breaks it sends the signal to the next system which activates the fire extinguisher and then the sprinkler system directs the fire extinguishing agent on the fire.
Sprinklers system is better than manual firefighting extinguishers as they don’t need a manual operator to operate the fire extinguisher system in such cases of a hazardous fire situation.

Based on the heads of the fire sprinkler system these are classified as three types:
This type of head in installed on the ceilings above of the offices and factories, etc. It directs the fire extinguishing agent stream in downwards direction in a dome shape after reflecting with a convex reflector.
- Sidewall Sprinkler Head.
This type of head is installed on the sidewalls and beams where the pipeline cannot be mounted on the ceilings.
- Upright Sprinkler Head.
This type of sprinkler head is installed in upright orientation which supplies streams in the upwards direction in a dome shape after reflecting it with a concave deflector.
