SMOKE ALARM AND FAULT TEST BOX. Used to test the alarm and fault indications on the cockpit control panel.
Test Equipment – Squib Tester
SQUIB TESTER. Used to test the squib firing circuits from the control panel to the extinguisher bottles and diverter valve.
Diverter Valve
Diverter Valve. Directs Halon to the affected cargo compartment
Extinguisher Bottle & Suppression Rack Assembly
Extinguisher Bottle Assembly. Provides one quick-discharge bottle to quickly saturate the affected cargo compartment with fire ‘Knock-Down’ protection. The “Knock-Down’ discharge is followed by a sustaining discharge of one or more bottles to sustain the required duration of protection. The EASA and Extended Duration FPS Kit Configurations use a larger second extinguishing bottle.
Suppression Distribution Tubing Assemblies
SUPPRESSION DISTRIBUTION TUBING. Pre-formed Extinguishing Agent Distribution Tubes deliver the extinguisher agent from the extinguisher bottle assemblies to the system nozzles in the cargo compartment. This tubing simplifies and reduces the time of installation.
Metering Regulator
Metering Device. Regulates flow of the sustaining bottle’s discharge to maintain the required duration of protection. The sustaining discharge provided by the metering device replaces the agent that is lost due to normal leakage of the compartment under all foreseeable operating conditions.
Penetrating Distribution Nozzle
Penetrating Distribution Nozzle. Directs Halon into the cargo load. One nozzle is installed in each detector enclosure.
Sustaining Distribution Nozzle
Sustaining Distribution Nozzle. Directs Halon to the top of the cargo compartment. Two are mounted to the ceiling of each compartment.
System Electrical Harnesses and Pre-wired Interface Tray Assembly
System Electrical Harnesses and pre-wired Interface Tray Assembly. Used to connect the FPS components to the aircraft’s electrical system and interfaces (i.e. Master Warning, Master Caution, Aural Warning, Cargo Smoke and Cargo Fire Annunciators, Lamp Test and Aural Warning Silence switches, and System Circuit Breakers.)
System Interface Tray Assembly
System Interface Tray Assembly (Pre-Wired). Located in the E & E compartment, this Interface tray simplifies the connections from the Fault Panel Assy, Smoke Detectors, and the CDSCP harnesses. It simplifies and shortens the time of installation, helps eliminate installation errors, and facilitates trouble-shooting. This tray assembly has connectors so that the shelf or rack [...]
