The difference between fire fast sprinkler head and ordinary sprinkler head:
1. Different reaction time
Under the same environmental conditions, the quick response sprinkler head will be more sensitive to heat than the ordinary sprinkler head, and the response will be faster to open for fire extinguishing.
2, water spraying amount is different
The fast response sprinkler has more water output and higher speed than the ordinary sprinkler, and its water jet can directly penetrate the flame to reach the surface of the burning object for extinguishing.
3. Different prices
A lot of fast response sprinkler heads are imported, because the sprinkler head performance and system design, installation, construction have special requirements, so the price will be more expensive than ordinary sprinkler heads.
