Research output: Contribution to conferencePaper, not in proceeding

Abstract

Arson in school buildings is a big problem in Sweden. The most severe and costly fires start on the outside of the building. In one-storey building the fire can easily spread to the attic space through ventilation openings in the eaves.
In this paper, research conducted in regard to detection of external fires in school buildings is presented. A maximum temperature linear detector, a differential linear heat detector and smoke detectors are studied and the performance of these are compared in the paper in regard to detection of external fires. The study is based on a full-scale experiment including 24 fire tests and the results are summaries in this paper.
It is concluded in the paper that predicting and modelling detection of fires on the exterior of a building is very difficult, due to the influence of different weather conditions. This is something that designers that are looking at the functional performance of detection systems needs to be aware of.
