Why Toronto contractors choose ValveAtlas pre-action valves
UL 260 and FM 1020 dual listing. Every pre-action valve we supply is UL 260 Listed and FM Class 1020 Approved. TFS accepts listed pre-action valves with factory trim kit, OBC compliance letter, NFPA 13 submittal package and UL 864 Ninth Edition releasing panel.
Single, double and non-interlock variants. UVPA-SI single-interlock (detection opens valve), UVPA-DI double-interlock (detection plus air loss both required), UVPA-NI non-interlock (detection or sprinkler opens valve) to match NFPA 13 application requirements. Double-interlock UVPA-DI-6 is standard for Toronto Tier IV data centers and cold storage freezer rooms to eliminate false trip from accidental sprinkler damage.
Factory-assembled trim with solenoid release. Complete pre-action valve trim per NFPA 13, including priming cup, main drain, alarm test, inspector test, solenoid valve release (24 VDC), pressure gauges, supervisory switches and low-air/loss-of-air switches. Plug-and-play delivery to Toronto data center, museum or cold storage mechanical room.
UL 864 releasing panel integration. UVPA-RCP releasing control panel coordinates detection from smoke detectors (UL 268), heat detectors (UL 521) and spot/beam detectors with solenoid release signal. Factory wiring diagram with SLC addressable loop provided for all Toronto projects.
Code and listing acceptance for Toronto
Ontario Building Code. The OBC adopts NFPA 13 with Ontario amendments for sprinkler installation. Pre-action sprinkler systems required in areas where accidental water discharge must be prevented per NFPA 13.
NFPA 13 pre-action systems. NFPA 13 pre-action requirements for single-interlock, non-interlock and double-interlock systems, design and trim govern Toronto pre-action valve installation. Our trim packages ship NFPA 13 compliant.
NFPA 72 National Fire Alarm Code. NFPA 72 governs smoke, heat and beam detection for pre-action system release. UVPA-RCP UL 864 Ninth Edition releasing panel provides NFPA 72 compliant detection and signaling.
Toronto Fire Services acceptance. TFS final inspection references NFPA 13 factory performance documentation, releasing panel wiring diagram and acceptance testing. Factory trim drawing and UL/FM certificates provided with every Toronto pre-action shipment.
Approved-equal submittals
Where a specification names a specific manufacturer, we prepare an approved-equal submittal package (listing certificates, dimensional drawings and material data) for review by the engineer of record and the authority having jurisdiction.
Detection and releasing for Toronto pre-action systems
Smoke detection for single-interlock. UL 268 Listed photoelectric or ionization spot detectors, or projected beam detectors for high-ceiling applications. UVPA-RCP SLC addressable loop supports up to 159 detectors per loop.
Heat detection for double-interlock. UL 521 Listed fixed-temperature or rate-of-rise heat detectors. Double-interlock requires heat detection activation plus sprinkler head air loss both before water is admitted.
Air-sampling integration. UVPA-RCP accepts input from aspirating smoke detection for Tier IV data center early-warning pre-action release.
Air supervisory for double-interlock. UVPA-AC CSA-certified compressor maintains 13 psi supervisory air on sprinkler piping. Loss of air signal combined with heat detection releases solenoid per NFPA 13.

Frequently asked questions (Toronto)
Are these pre-action valves accepted by TFS? Yes. Our pre-action valves are UL 260 Listed and FM 1020 Approved. TFS accepts listed pre-action valves with factory trim kit, OBC compliance letter and NFPA 13 submittal package.
When do I need single-interlock vs double-interlock vs non-interlock? Single-interlock (UVPA-SI): detection opens valve, pipe fills with water, sprinkler operates on heat. Double-interlock (UVPA-DI): heat detection plus air loss both required, which eliminates false trip from accidental sprinkler damage, standard for Tier IV data centers and cold storage freezer rooms. Non-interlock (UVPA-NI): detection or sprinkler opens valve, standard for museum and archive collections.
Do these valves work with a UL 864 releasing panel? Yes. UVPA-RCP is UL 864 Ninth Edition Listed releasing control panel. Factory wiring diagram with SLC addressable loop, smoke detectors, heat detectors, manual release stations and solenoid output provided.
What is the delivery time to Toronto? Factory-assembled trim kits ship 4 to 6 weeks from order. Stock UVPA-SI-6 and UVPA-DI-6 ship 2 to 3 weeks. Same-day truck freight from Toronto HQ.
