Preaction Sprinkler Systems
PreactionSystems
Preaction fire sprinkler systems are designed to enhance safety and prevent accidental water discharge. Similar to dry sprinkler systems, piping is filled with air or nitrogen. However, in a double interlocked preaction sprinkler system, two separate events must occur before water is released to activate the preaction system. The first step is to trigger the fire detection system, which can be done through smoke detection, heat detection, or a combination of both. Once the fire detection system has been activated, the system is armed and ready for water release. The second step is for individual loss of air of a fused sprinkler head to activate, release water and suppress the fire.
Preaction systems are used in environments where accidental water discharge could cause significant damage, whether in high-risk areas or locations with colder temperatures. Common places include data centers, museums, computer rooms, clean rooms, and cold storage freezers. Ahern has been fire safety-focused and designing custom preaction sprinkler systems for decades. We will work with you to find the best solutions to your needs.
Since 2010, over 99% of Ahern's work was completed without follow-up warranty replacement.

Types of Preaction Sprinkler Systems
There are three different types of preaction systems, each offering varying levels of protection against accidental water discharge.
- Double Interlocked Preaction System – this is the most fail-safe option, requiring both a detection event and the activation of a sprinkler head before water enters the pipes, offering maximum protection against accidental release.
- Single Interlocked Preaction System – designed to reduce the time taken to apply extinguishing water while still providing some protection against accidental water deployment in the protected area. Upon a detection event, the main valve will open, filling the piping with water.
- Non Interlock Preaction System – in a non-interlock system, water can be released without confirmation from an electrical detection device.
Each of these preaction systems offers a different balance of protection and response time, allowing for customization based on the specific needs of the environment being protected. Choosing the right system depends on the level of risk and sensitivity to accidental water damage. Ahern can help you understand which type is best to safeguard your facility.
