Fire Sprinklers and Systems

 

How a fire system works:

​

Water filled systems are the most common and are normally

connected to a public water source through a street connection.

It come from the source to a valve and can be turned off and on

for repair, testing and maintenance. These valves are designed to

be open and closed slowly. DO NOT SHUT OFF THE SYSTEM

UNLESS YOU ARE SURE THE FIRE IS OUT! The valves are usually

monitored by an off sire company that can monitor water flow,

valve tampering, freezing and air pressure. The fire system is water

and air tight. If a usable link (sprinkler head) is opened, water wil

l flow through the opened head(s) only.

​

Anti-freeze filled system or section:



Works the same as the wet (water) system but allows the pipes and heads to operate in below freezing temperatures. Some sections must be protected from freezing temperatures. 



Dry system:



​Same as a water based system, except the pipes are filled with air and can be from an air compressor or air tanks. The water is held back at the dry valve by the air pressure until the system is opened b a fuseable like head(s).
