ABSTRACT

This study is aimed to reduce failure rates and failure modes through the arrangement of the list corresponding to the component of the electrical and electronic in the user circuit of a P-type receiver. This paper analyzes a user circuit of monitoring and alarm systems in buildings. In the user circuit, the heaviest failure modes are shown in cables. The results of a risk priority number (RPN) analysis shows that a total of 6 failure modes is shown in the parts of contact/intermittent (112) and arcing/sparking (121) of the cables. Moreover, a mechanical failure (301) and an intermittent/degraded operation (302) of On/Off switch, high contact resistance (401) of a capacitor, and a drift (501) of IC are the other modes of the failure. Consequently, we find that the part of frequent breakdown is the cable and verify that the defect of cable connectors causes lots of failures of user circuits such as contact/intermittent. We expect that these findings will contribute to increase the quality of firefighting supplies and their life-spans.
