Abstract
A fire protection system includes a fire extinguisher including a housing. The housing includes an extinguisher outlet and a burst disk. The burst disk configured to retain a volume of fire suppressant material in the housing. A firing cartridge is operably connected to the housing. The firing cartridge includes an output charge, and an ignition charge that, when detonated, causes release of the output charge to rupture the burst disk and release the volume of fire suppressant material through the extinguisher outlet. An optical fiber is configured to transmit a light signal toward the ignition charge to heat and detonate the ignition charge. A light source is operably connected to the optical fiber to transmit the light signal along the optical fiber.
