Abstract

An ignition unit for a fire extinguishing assembly has an ignition unit housing with a firing pin disposed within the housing. A spring is coupled to the firing pin, and a restraining device holds the pin in place in the housing. A formed eutectic holds the restraining device in place such that when the eutectic deforms, the firing pin is released and moved by the spring in a desired direction.
