Roof-Top Sprinkler SystemsFACT: In the face of an advancing wildfire, a structure with a properly implemented FireSmart Program in combination with an operational exterior rooftop sprinkler system, has a survival probability of above 90%.
Sprinklers are one of the oldest methods but one of the newest technologies in wildfire control and property fire protection in wildland areas. Unlike the sprinkler systems found inside buildings, these outdoor units are not intended to put out a fire. Instead, they work in the following manner:
This approach has proven to be highly effective with the Ontario Ministry of Natural Resources being internationally recognized as leaders in the area. When Ontario is sends forestfire fighting personnel to other provinces or countries, sprinkler crews make up a significant component of the team.
Various components are available to provide you with complete protection including:
A rooftop sprinkler system is not just for fire protection. Because it is designed to provide gentle water distribution over a large area, it is a perfect means of keeping your landscape green and lush. On a hot summer day, it will even provide natural cooling - no need for an air conditioning system. Not only will your surroundings look attractive (when everything around you is dried and brown) but it will be fire safe.

Did You Know That ...
Designed primarily for attachment to a vertical surface such as a roof fascia, to support 1 sprinkler head. Bracket backplate is 8" by 5" by 3/16" aluminum plate welded to 3/4" NPT threaded tube on a 1.25"
offset. Mounting plate has 4 pre-drilled holes. Additional mounting holes can be easily be field drilled for precise placement. Bracket plate can be trimmed for custom fit.
This sprinkler assembly is ready for attachment to a vertical surface such as the fascia of a building. It consists of a agricultural grade (WadeRain) impact sprinkler and the fascia bracket shown above. Included are a brass coupling for sprinkler attachment and a brass swivel garden hose coupling for attaching the supply hose.
With a pressure of 60 psi, performance of 66.6 litres per minute (17.6 gpm) can be anticipated with a 33.5 m (110') full-circle coverage.
Plan to use high quality 3/4" or better hose should be used to handle the higher flows and operational pressures involved. Any of the GHT coupled hoses on our website are suitable for sprinkler supply purposes.
Railway Sprinkler MountActually, this is a water thief with an integrated sprinkler head. It was originally designed for fire protection of wooden railway bridges. With a height of under 7½", it can be seasonally secured to the ties between the rails without interference from passing rolling stock. When needed, attach fire hoses to the sprinklers to wet the area.
The base plate is 3/16" steel measuring 8" x 10" with 4 pre-drilled 3/8" mounting holes. Water flow is unobstructed through the 1½" waterway to subsequent uses down the line — connections are forestry quick connect (FQC). The port to the sprinkler is 3/4" NPT. There is no flow control.
The mount is of sturdy steel construction painted industrial grey. Weight is 9.2 lb. with WadeRain WR-33 sprinkler installed. For horizontal placement only.
Hydro-Wick Spike Sprinkler
The Hydro-Wick heavy duty sprinkler is designed for use with standard forestry fire pumps. A high performance model with applications including prescribed burns, exterior building protection, and fire line protection. Also works well for landscape watering and general cooling on a hot summer day. Supplied with splitter type nozzle and 2 extra nozzles of different sizes. Has spike support with mounting holes providing for a variety of placement options. Female GHT fitting is standard allowing connection to garden hose style coupling. Full-circle coverage. This is the workhorse for wildland fire crews.
