Chemical sensors for fire detection and nuisance rejection under EN-5420 standard conditions and reduced-scale chamber

The dataset was acquired using a gas sensor array placed in the celling of a validated standard fire room (240 m3) located in Minimax Company. The dataset includes measurements of three different campaigns that were performed over 15 months. The dataset includes standard EN-54 smoldering fires and non-standard smoldering fires (such as plastic fires; PVC, cables Fire). In order to generate scenarios that may result in false-positive alarms when gas sensors are used, different nuisance experiments were also performed (such as cleaners, and air fresheners). Additionally, an additional measurement campaign was performed in a small chamber. The small-scale experiments dataset includes scale-down replicates of the fire and nuisances experiments performed in the standard fire room (EN-54 smoldering fire experiments, non-standard fires, and nuisance experiments).
