Abstract
A method of actuating an extinguisher system may comprise retaining a broadhead cutter in close proximity to a burst disc surface, receiving an impulse signal, actuating a spring release mechanism in response to receiving the impulse signal, driving a cutter shaft towards the burst disc surface in response to actuation, and piercing the burst disc surface via the broadhead cutter coupled to the cutter shaft.
