Electrical fire monitoring system belongs to the leakage monitoring early warning system, and the traditional automatic fire alarm system is different, electric fire monitoring system of early warning is in order to avoid losses, while the traditional automatic fire alarm system is to reduce a loss, this paper introduces the electrical fire equipment and fire control system design application and basic components and the principle of work.
1, system characteristics:
Electrical fire monitoring system belongs to the early warning system, and the traditional automatic fire alarm system is different, electric fire monitoring system of early warning is in order to avoid losses, while the traditional automatic fire alarm system is in order to reduce the loss of. So, that is why no matter new or reconstruction project, in particular have installed automatic fire alarm system unit, still require the installation of electric fire monitor system root causes.
2, introduction:
In recent years the electrical fire accidents is high, with was 2005 exemple, ten fire fatalities in the largest number of two in Liaoyuan Central Hospital of Jilin province fire, Shantou Southern China hotel fire, are electrical fire, concerned expert actively urged to take effective technical measures of electrical fire, to curb the rising trend, the relevant government departments attach great importance to, in succession formulate or amend the relevant standards and specifications, requirements in the building of electric leakage fire alarm system. In order to prevent electrical fire, reduce fire hazards, reasonable twenty electrical fire monitoring system of electrical fire monitoring system, guarantee the construction quality and the use of performance, protect the personal and property safety, these rules are formulated. " Fire protection design of tall buildings" GB5004595 ( 2005 Edition) partially revised articles 9.5.1, mandatory national standard" residual current protection device installation and running" GB13955-2005 stressed the importance of residual current operated protective device for preventing grounding fault in electric fire caused by protective function, requirement in the building installation of residual current action fire control system. Can say, the prevention of building electric fire, set the electric leakage fire alarm system in the national standards and norms have been basically complete (and other relevant specifications are approval ), future site design, application of the electric leakage fire
