The Trimpac Model D-1 D-1B Surefire Preaction System is an engineered fire suppression valve assembly deployed in critical commercial environments—such as data centers, warehouses, and fragile asset facilities—where preventing accidental water discharge is vital. This single interlocked preaction system operates via a two-stage activation process, requiring both system detection and sprinkler activation to release water into the piping network. This mechanism eliminates false water discharges and safeguards sensitive infrastructure from unintended moisture damage.
Designed to comply with NFPA 13 for installation of sprinkler systems and NFPA 72 for national fire alarm and signaling code requirements, this assembly meets rigorous life safety mandates. It integrates seamlessly with existing fire alarm networks and automatic sprinkler setups, satisfying strict code compliance for high-stakes commercial and industrial hazard areas.
