Abstract

Monitoring and controlling apparatus and related methods for use with collective protection shelters or other isolation environments utilizing one or more digital processors to monitor and control the operation of the shelter. The apparatus affords shelter design and functional growth flexibility, along with diagnostic and prognostic capability, including condition based maintenance, interactive electronic manuals, and access to systems for replacement parts requisition. Further, the physical and functional expandability of the apparatus affords easy incorporation of shelter design changes, user interface design changes, and sensor design changes as well as improved functional and operational flexibility. The system also decreases volume and weight over prior designs.
