Abstract : Two Halon 1301 dispensing systems, modular nozzle and perforated tube, were designed and installed in an obsolete but completely furnished CD7 passenger cabin. For each system, agent distribution was continuously measured during discharge and for a period of 10 minutes at approximately 20 locations throughout the unpressurized cabin. The effect of Halon 1301 discharge on cabin temperature, noise, pressure, and visibility was also measured. The modular system was judged to be best by virtue of its producing more rapid and effective agent distribution resulting in greater potential fire-protection capability. Installation of the Halon 1301 dispensers along the ceiling for both systems minimized the known possible transient adverse effects upon passengers from agent concentration overshoot, discharge noise, over-pressure, and reduced temperature.
