Introduction

Use and management of buildings through various detection device discovery and control of fire, so that the buildings meet safety standards, and reducing Fire damage. This part of GB/T 31540.1 specified in a variety of active fire fighting facilities Subsystem 4 building set in the analysis and evaluation. Subsystem 4 can be used to calculate various fire detection detection time, the operating time of fixed fire extinguishing devices and other fire control It means the response time of fire smoke. Calculation process requires the use of a subsystem, subsystem 3 is set according to the fire scene and provided Given fire scenario calculated fire smoke temperature, concentration and flow rate. The reference to the relevant part of the Fire Code, ISO /TC21 fixed fire extinguishing system related standards, combined with setting a fire scene When using these standards do engineering judgment, to assess the effect of different fire fighting equipment fire heat release rate. This section also uses engineering methods important output (detection time, start time and extinguishing system performance) was evaluated subsystem 4 Assessment and details the physical and chemical processes need to be considered in the evaluation process, evaluation methods, and evaluate information needed to assess the conclusions. Fire Safety Engineering Guidelines Part 4. detection, and fire started

1 Scope
