Wireless Fire Detector (WFD)

Systems & Processes Engineering Corporation (SPEC) proposes a Wireless Fire Detector system (WFD) which consists of a suite of ultra low power, battery powered fire sensing modules, and repeater modules which are deployed throughout an aircraft in separate compartments, interconnected via an encoded low bandwidth network to a cockpit control unit. The sensors use solar blind UV sensors with high bandwidth processing, which allows discrimination between fire, bullet passage, and electrical corona breakdown. Upon detecting either fire or corona breakdown, the unit transmits the condition and its code, used to identify its aircraft location, to the cockpit control unit using an adaptive, flexible, multimode network using the array of radios. Communication between sensor modules and the cockpit control unit will be enhanced by implementing a combination of information cloud, information bridge and information shuttle to insure each module has connectivity to the network. Repeater modules located on both sides of the bulkhead near an existing through bulkhead connector allow transmission of the signal without aircraft structure or wiring modification. By using low power units, with one year battery life, no aircraft wiring modifications are needed to install the system.
