What Is SureFire® and When Should You Choose It for Preaction Protection?

SureFire® is a preaction release concept designed for spaces where water damage from an accidental discharge would be a major concern. Detection activates the release system and fills the piping, but water does not discharge until a sprinkler opens from heat.

You should choose SureFire® when you need both early detection and strong protection against unwanted water release. It is especially suitable for critical equipment rooms, archives, communications spaces, and other high-value occupancies.

The main options mean:

• Single interlock SureFire: detection opens the preaction valve and fills the piping; sprinklers still must open before water discharges.
• Double interlock SureFire: both detection and loss of air pressure from sprinkler operation are required before the valve releases, giving even more protection against accidental filling.

Its added value is confidence. You get faster fire response logic than a standard dry system, while greatly reducing the chance of unwanted water discharge from piping damage or isolated sprinkler issues. If your main question is “How do I protect sensitive assets without overexposing them to water risk?” SureFire® is a strong answer.
