The operational-reliability assessment of a power supply for the alarm system of a transport facility
Abstract
The following paper presents issues concerning a power supply for the alarm systems used in transport facilities. It describes the guidelines included in the polish standard PN-EN 50131-1:2009 „Systemy alarmowe – Systemy sygnalizacji włamania i napadu – Wymagania systemowe” (Alarm systems – intrusion and hold-up systems – system requirements), a power supply in particular. Then the operational-reliability assessment of a system consisting of a main power supply (230V AC power grid), redundant UPS and diesel generator was made. The aim of that was to obtain formulas for particular state probability values in a symbolic form (Laplace’s). The further assessments taking other types of power supply into account will be presented in the forthcoming papers.
