FIRE DETECTORS LOCATION IN SMALL PREMISES

There is considered the process of burning products during fire in rooms. Logical justification of requirements of the clause 13.3.6 of SP 5.13130.2009 «Fire protection systems. Automatic fire alarm and fire extinguishing installations. Norms and design rules» is given. There is formulated the protection problem of spaces of small volume where it is impossible to follow the requirement of clause 13.3.6 of SP 5.13130.2009 regarding providing the minimum distance between fire detectors and surrounding objects for the physical reasons. Requirements to conditions of carrying out the fire tests to find optimum place for fire detectors in small protected volume are developed. The received data concerning reaction time of fire detectors depending on the place of their installation are analyzed. Optimum locations for fire detectors from the point of view of ensuring maximum efficiency of ignition detection are defined.
