- Abstract
- This Residential Smoke Detector Reliability Handbook is designed to provide a means for the accurate prediction of smoke detector failure rates in a residential environment. The methodology developed by which a smoke detector critical failure rate can be determined is divided into three major sections. Section 1.0 contains the parts stress reliability predication techniques for each major generic component type currently being used in residential smoke detectors, or exhibiting the potential for being in future designs. Section 2.0 through the application of FMECA and/or FTA techniques, presents the guidelines for the determination of those components, and their associated failure modes, which are considered critical to the audible warning capabilities of the detector. The process of applying the predicted failure rates of Section 1.0 to the FMECA/FTA guidelines of Section 2.0 will result in a critical failure rate for residential smoke detectors; i.e. the rate at which failures that will not trigger the audible alarm circuitry may occur, thus negating the protective characteristics of the unit. Finally, Section 3.0 discusses methods characterized as most critical to smoke detector operation, to efficienly detect and eliminate infant mortaility failure.
