DICTATOR HLS Thermal Bolting for Fire Protection Doors

During a fire it can happen that large door leaves, although safely closed at first, are pushed open in some places due to high temperatures and the subsequent pressure difference. Through the forming gap the fire may expand in spite of the fire protection door.

Operating principle

In case of the DICTATOR HLS thermal bolting a bolt extends as soon as a certain temperature is reached and thus blocks the door leaf in the door frame.
