Product Description
The Model XL Commercial is a quick response sprinkler.
It is a fusible solder link type automatic sprinkler designed
for standard coverage applications. These sprinklers have
demonstrated response time in laboratory tests which is five
to ten times faster than standard response sprinklers.
The quick response feature enables the Model XL Com-
mercial Sprinklers to apply water to a fire much faster than
standard response sprinklers of the same temperature rating.
Modern architectural designs require sprinklers that pro-
vide not only the best fire protection, but also an attractive
appearance. The Model XL Commercial meets both criteria.
The flush style of this sprinkler provides for an aesthetically
pleasing installation by concealing the entire sprinkler oper-
ating parts with the exception of the heat sensing link. Only
