Pierre Thibault was a Canadian fire apparatus manufacturing company located in Pierreville, Québec, Canada. In addition to fire apparatus, the company also sold two models of vertical sirens, the Type 3 and Type 5. These sirens are mainly found in the province of Quebec, where they are very common fire sirens, with particular concentrations in the Beauce and Estrie regions. A few other examples have been documented as far as Newfoundland and British Columbia.
These rebranded Federal Signal Model 5 C2 1/2 units use an improved weatherproof housing to protect the siren from harsh Canadian winters, with a taller, steeper rain shield and a much larger, steeper skirt to help force snow to slide off of the siren instead of building up on top. The open mesh screens have also been replaced with louvred grilles similar to some Fedelcode sirens. Due to the sheer weight of accumulated snow, the housings of a regular C2 ½ could be crushed or damaged. Like their Federal counterparts, they follow the quirk of 1 ph units often being taller than 3 ph units due to using taller motors. These sirens are exclusive to Eastern Canada, with units having been found in the provinces of Quebec and New Brunswick. It is one of the most common sirens in Quebec and are largely only found in that province. Little is currently known about the internals of the sirens, although it can be assumed that they share the same core as the standard C2 ½, although this is completely speculation. These sirens are no longer produced.
