Always closed steel door DSTO
Fire protection equipment with a periodically closing mechanism during a fire!
It is a specific fire protection equipment with a periodically closing mechanism in the event of a fire. This periodically closing specific fire protection equipment automatically closes when the release hook is disengaged by signals from smoke detectors or fire alarms. You can choose the angle of the open hold (90° or 180°) and whether or not to include a crawl door for evacuation, and you can also specify the opening direction of the crawl door based on the evacuation route. It is custom-made with high precision dimensions in 1mm increments. * We believe that it meets the requirements for specific fire protection equipment, but opinions may vary depending on the administrative agency conducting the inspection, so please be sure to check with the relevant administrative agency in your installation area in advance.
