Title: FIRE SUPPRESSION SYSTEM MODULES AND METHODS OF SEALING
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.
