Pre-Action Sprinkler Systems

Kane Fire Protection

What are Pre-action Sprinkler Systems?

Pre-action sprinkler systems utilize closed sprinkler heads that are attached to a pre-action valve connected to a water supply. When a fire detector is activated, water will enter the system, but the sprinkler heads will not open until they detect heat.

These systems help prevent water damage in the event of a false alarm due to their dual action requirement. On the flip side, they are less reliable than your regular wet sprinkler system due to the complexity of the piping and wiring.

At Kane Fire Protection, we understand that when your fire suppression system needs repair, you don’t have time to spare. That’s why we have 24/7 repair services available to our customers and carefully trained technicians on call to identify and fix your problems. 

Pre-action sprinkler systems are known to be extremely reliable, but they do need repair and maintenance every now and then. Many of our customers call us with concerns but aren’t sure how to tell if they are in need of repair. Here are some signs that you need to give us a call:

Tripped alarm

This could be a sign of a bad device (flow switch/pressure switch) or could mean you have a leak on a dry system and the air compressor can’t keep up.

The best way to tell if you are dealing with corrosion is if you see signs of rust, discolored water, or smell a foul odor. You can tell whether or not there are signs of rust by looking for a green tint on the exterior of your sprinkler head or pipes.

You can determine whether or not there is leakage if you start to notice watermarks on your ceiling or if your sprinkler heads start to drip or spray. For dry systems you may have a leak if your air compressor is running frequently. 

Pre-action Fire Sprinkler System Inspections


Even though our design systems and installation are tested and proven to be reliable, regular inspection is critical to ensure safety in your building. Chances are, your pre-action sprinkler system sits idle a majority of the time, making it easy for any breaks or problems to go unnoticed. Having your system regularly tested not only protects your investment in the system, but also protects your building and its occupants.

Regular fire sprinkler testing is also required by the IFC (International Fire Code) and the NFPA (National Fire Protection Association Codes). Our detailed inspections help keep you up to date on the state of your fire sprinkler system without feeling overwhelmed. Our testing process includes inspection of air pressure level, water pressure levels, fire alarms, water flow alarms, and connections to the pump, tank and fire department.
