Abstract
According to one aspect, a fire extinguisher includes a fire extinguisher reservoir and a fire extinguisher outlet burst disc that forms a discharge barrier between the fire extinguisher reservoir and a discharge head to retain a pressurized fire extinguishing agent within the fire extinguisher reservoir. The fire extinguisher actuator assembly includes a cutter positioned within the fire extinguisher proximate the fire extinguisher outlet burst disc. The fire extinguisher actuator assembly also includes a motorized activation device having a drive shaft. The motorized activation device is operable to rotate the drive shaft and push the cutter to pierce the fire extinguisher outlet burst disc, thereby releasing the pressurized fire extinguishing agent through the discharge head.
