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.
Highlights
Failure to comply with fire safety requirements often leads to serious consequences, such as property damage, loss of life
It makes sense to use a signal line with serial addressing with the transmission of information by analog, which helps to facilitate the operation of the entire system, is more "survivable" in case of breakage or short circuit [6]
The address system is more expensive, it is recommended to use a signal line with serial addressing with the transmission of information by analog, which will simplify the operation of the entire system, will preserve the capacity at breakage or one short circuit [11]
Summary
Failure to comply with fire safety requirements often leads to serious consequences, such as property damage, loss of life. It makes sense to use a signal line with serial addressing with the transmission of information by analog, which helps to facilitate the operation of the entire system, is more "survivable" in case of breakage or short circuit [6]. Such situations may result in the disconnection of part of the system or all fire detectors. The address system is more expensive, it is recommended to use a signal line with serial addressing with the transmission of information by analog, which will simplify the operation of the entire system, will preserve the capacity at breakage or one short circuit [11]
