In ALARM STATE: The effect of an average temperature expands the helium (inert) gas, which in turn closes the ALARM switch, or the effect of heat caused by a flame or hot gas, releases core (active) gas from the hybrid core, which in turn closes the ALARM switch. In both cases, the detector sends a fire signal. In FAULT STATE: In the event of gas pressure loss (pipe fracture or cut off due to a torching flame), the INTEGRITY switch opens and generates a fault signal.

Duct type smoke detectors are installed in the Avionics compartment, in the emergency compartment, in the IFE compartment and in the Additional Electronic compartment. Ambient type smoke detectors are installed in the cargo compartment, in the lavatory, in the cabin sub-compartment and in the crew rest compartment. Duct Type Smoke Detector The duct type smoke detector is installed on the air duct. The photoelectric cell senses airborne combustion particles, transported by the air ducted. This detector is installed housing with an air inlet and air outlet. Ambient Type Smoke Detector This type of smoke detector is primarily used in monitored and closed areas. An optical cell senses obscuration resulting in presence of airborne particles. These airborne particles enter through the open housing. Smoke Detector Description These two types of smoke detector cells are based on the principle of reverse scattered light. Each detector includes a light source, a labyrinth and a photocell arranged in a horizontal plane so that the photocell cannot receive light. But when there is smoke, the smoke particles reflect and diffuse part of the light beam. The smoke detector has two chambers: -the reference chamber -the measurement chamber. The reference chamber manages the differential pressure and the temperature differences and makes sure that the detectors operate on ground and in flight with the same level of sensitivity. The measurement chamber compares the analog voltage of the sensor with the different levels of the threshold (fault, normal and smoke).

The CIDS-SDF is a segregated hard and software platform within the ARINC 600 CIDS Director. An AFDX interface gives the primary communication to other aircraft systems. The DEU-Bs are linked with the Directors by Ethernet data busses called "Middle lines" The DEU-B is a LRU, which operates like a remote data concentrator, It manages and power supplies up to 8 smoke detectors. A dedicated fault and alarm outputs as well as a reset input enable local indication and control of smoke detection functions. The FAP is the main user interface with the CIDS. The sub-panel of the FAP has the SMOKE RESET functional areas to reset the audio smoke alert. The MINI-FAP has in basic pages the smoke detection item to visualize the location of the detection and a SMOKE RESET hard key. The Fire Extinguishing System (FES) panel is used to control and indicate the fire extinguishing procedure. It is installed in the stair house. The FES panel is a human interface to command ignition of the fire extinguishing bottle and give indications on the status of the fire extinguishing. The Fire Extinguishing Data Converter (FEDC) controls and monitors the condition of each installed fire-extinguishing bottle and detects the extinguishing agent pressure inside. It operates on the principle of an interface translator between discrete signals and CAN bus. The FEDC is a remote data concentrator, monitoring the pressure switches and the squib circuit of the Fire Extinguishing System. It ignites all squibs of the agent bottle.

The bottles, made of stainless steel, contain the fire-extinguishing agent, halon 1301 and are hermetically sealed and refillable. Each bottle has: - a Temperature-Compensated Pressure Switch (TCPS), - a fill and a safety relief valve. Each discharge head has: - an electrically operated cartridge, Each cartridge has two squibs (squib A and squib B) receiving a separate power supply (HOT BUS and DC BUS power). When the electrical power supplies both squibs, the cartridge explodes and ruptures the metal diaphragm in the discharge outlet. Extinguishing agent flows through the discharge head into distribution pipes. The diverter valve has two outlets to direct the Halon via piping one for the FWD and the other one for the AFT/BULK Cargo Compartment. Each outlet is sealed with a plug. A pyrotechnical cartridge opens it. The Flow metering equipment regulates the outflow of the second and the third bottle, maintaining the extinguishing agent concentration to a minimal time of 240 minutes. It includes a water absorbing filter element, a solid particle filter element, a pressure switch, a pressure reducer, a restrictor and a check valve. Four nozzles are located in the FWD cargo compartment and five are in the AFT/BULK cargo compartment. There are installed on the ceiling in the same cavity and between the two smoke detectors, and are protected by a metallic grid.
