Abstract: Fire suppression systems (10) include modules (14x) interconnected with a centralized controller (12). The modules (14x) are configured, assembled and sealed for system operation in harsh environments. Modules of the system include a printed circuit board (PCB, 32, 132), a microprocessor (34), and an operative component (36) assembled within a housing (30, 130). A gasket member (38) is disposed about the component to form a seal about the component. Operative components may include fire detection elements (14x, 50) or an LCD screen (36, 236). Modules of the system can include an encapsulant compound for filling a void between the housing inner surface and the printed circuit board. Modules of the system can include a sealed chamber with a port to interface a computer device. A power module of the system includes a sealed housing with connectors positioned to protect against moisture and debris and an isolating switch to permit maintenance of the system.

Abstract: A tire suppression system includes a centralized controller and a plurality of modules (14). Each module includes a housing (30), a printed circuit board (32) with a mounted microprocessor (34), a first connector (36) including a first pair of data wires (38) mounted to the board; and a second connector (40) including a second pair of data wires (42) mounted to the board so that the printed circuit board electrically connects the first and second pairs of data wires. The modules are interconnected with the central controller to define data buses for centralized fire detection, user interface and system response. The connectors of each module interconnect the plurality of modules in series to the central controller.
