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. Fire sprinklers are extensively used worldwide, with over 40 million sprinkler heads fitted each year. In buildings protected by properly designed and maintained fire sprinklers, over 99% of fires were controlled by fire sprinklers alone.

Artificial Intelligence Guided Fire Sprinkler Apparatus and Method

An artificial intelligence guided, flame tracking fire suppression liquid spray nozzle on a pan and tilt turret base is recessed into a niche of wall mounted fire suppressant tank with a hinged flip door panel. A built-in smoke detector flush with the tank, senses for smoke and in an event fire breaks out, the door panel flips down and drops the pan and tilt turret base to search and lock on and track the flame. The spray nozzle splashes the flame with fire suppressant from its limited volume wall mounted suppressant tank via a high pressure spray pump. The wall tank is backed up to a high volume refill tank located remotely. The system shuts down when the fire is extinguished. Additionally, a hand gesture signal on site or a remote command via Wi-Fi in an emergency provides a fail-safe shutdown to assure premises will not suffer destruction.
