Code and listing acceptance for Toronto

Ontario Building Code 3.2.5 and 3.2.1. OBC 3.2.5 adopts NFPA 13 for sprinkler installation. Dry pipe sprinkler systems are required in OBC 3.2.1 spaces subject to freezing where wet pipe systems cannot be maintained above 40 degrees F (4 degrees C). Typical Toronto applications include unheated parking garages, loading docks, freezer warehouses, unheated attics, aircraft hangars and refrigerated cold storage.

NFPA 13 Chapter 7 dry pipe systems. Section 7.1 (general), Section 7.2 (design), Section 7.3 (water delivery time), Section 7.4 (acceptance testing) govern Toronto dry pipe valve installation. UNIVAL trim packages ship NFPA 13 Chapter 7 compliant with factory documentation.

NFPA 25 Chapter 13 dry pipe valve inspection. Annual trip test per NFPA 25 Section 13.4.3 verifies water delivery time under 60 seconds. UNIVAL UVDP-6/UVDP-8 designed for rapid trip and reset with minimum maintenance. TFS annual acceptance test support available.

Toronto parking garage standards. Toronto Green Standard and OBC 3.2.1.9 require sprinkler protection in parking garages. Dry pipe system mandatory for unheated garages (below-grade, ramp-access, exposed deck). UNIVAL UVDP-6 factory trim standard for Toronto parking structures.

Victaulic FireLock NXT, Tyco DPV-1, Viking E-3 and Reliable Model F substitution for Toronto projects

Victaulic FireLock NXT Series 756 and 758. Substitute UNIVAL UVDP-6 or UVDP-8 at matching size and working pressure. Same UL 193/FM 1041 listing, same ANSI Class 250 flange/groove, same NFPA 13 Section 7.2 water delivery compliance.

Tyco DPV-1 and DPV-2. Substitute UVDP-6 or UVDP-8 at matching size. Matching differential-type dry pipe valve with low-differential rubber-faced clapper for reliable operation at low air-to-water ratio.

Viking E-3 and Model G-6000. Substitute UVDP-6 or UVDP-8 at matching size and sprinkler count. Factory water delivery time calculation provided for hydraulic design verification.

Reliable Model F and Model DDX. Substitute UVDP-6 or UVDP-8 at matching duty. Identical NFPA 13 Chapter 7 trim configuration.

Air compressor and QOD sizing for Toronto dry pipe systems

Air compressor sizing per NFPA 13 Section 7.2.2.1. UVDP-AC air compressor rated to fill system to normal air pressure within 30 minutes. Typical Toronto parking garage 400-sprinkler system requires 1 HP compressor; freezer warehouse 750-sprinkler system requires 3 HP. Factory sizing calculation provided per system volume.

Accelerator (UVDP-ACC) application. Required for dry pipe systems exceeding 500 gallons capacity per NFPA 13 Section 7.2.4.1. UVDP-ACC reduces water delivery time to under 60 seconds by rapidly equalizing air pressure differential across the dry pipe valve clapper.

Exhauster (UVDP-EXH) alternative. UVDP-EXH exhauster provides alternative QOD via rapid air exhaust from the system side. Selected based on system volume, pipe schedule and hydraulic layout.

Air maintenance device (UVDP-AMD). UVDP-AMD automatic air makeup regulator maintains system air pressure per NFPA 13 Section 7.2.6. Prevents false trip from minor air leakage and maintains supervisory air pressure for UL Listed supervisory service.
