Abstract
A sprinkler includes a compartment that surrounds its riser portion in an offset or asymmetrical configuration. More specifically, the distance of the compartments walls from those of the riser vary (i.e., increase or decrease) at different locations surrounding the riser. Put another way, the riser is closer to one side of the compartment than other sides of the compartment. This non-concentric configuration allows larger components to fit inside the compartment than would otherwise fit if the riser was symmetrically surrounded by the compartment.
