Research of noise-proof feature of addressable fire indication system with sequential addressing

Abstract

Currently, one of the ways to quickly detect fires in buildings is an automatic fire alarm system. The alarm loop is the most “vulnerable” part of the security and fire alarm system. This article is devoted to the study of the stability of the address fire alarm system with serial addressing under the influence of electromagnetic interference and other interfering factors. During the study, the system performance was evaluated when changing the parameters of the communication line and the stability of the transmission of the measured controlled parameter from the multicriteria detector having a heat and smoke sensor to the control panel of the DEMP DT №1. The influence of electrical impulse noise on the stability of the system was evaluated.
