Fire escape automatic sliding doors 300 EF with a fire resistance EI30 are intended to be installed at the borders of fire sectors, as well as on the escape route crossings. The doors combine the day – to – day comforts of a sliding door with a safe solution in case of fire and are primarily used to prevent spread of fire. Fire escape automatic sliding doors must ensure a safe evacuation of people and goods, and at the same time prevent the spread of fire. In normal circumstances these doors function as standard automatic sliding doors enabling easy passage. However, upon activation of a fire signal, power failure or upon malfunctioning of the doors, they will close automatically and completely mechanically. The doors automatically switch to swing operating mode and allow for easy swing opening of the leafs and a safe evacuation. They can be opened with a pull handle or panic push bar and will close automatically, due to an integrated self-closing mechanism. Therefore, fire protection is fully guaranteed.
