A fire protection system includes two or more fire extinguishers. Each fire extinguisher includes a housing, the housing including an extinguisher outlet and a burst disk. The burst disk is configured to retain a volume of fire suppressant material in the housing. A firing cartridge is operably connected to the housing and 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 selectably transmit a first light signal to selectably activate a first fire extinguisher or a second fire extinguisher of the two or more fire extinguishers.
