How long will the protection last?
With fire protection doors, the protective effect (fire resistance time) is limited by time. With smoke protection doors, this cannot be stated with certainty. This is because the tolerated smoke volume depends on the ventilation conditions (the air transfer rate) and the size and height, primarily, of the respective room, among other things. Roughly speaking, an approximately 30 metre long hallway can be passed through safely without wearing a respiratory device for about ten minutes, with the current limit values and so-called incipient fire.
Smoke protection doors are equipped with an identification plate that lists the standard designation, the manufacturer’s product designation, the number and date of the test reports, and the year of manufacture.
SMOKE-PROTECTION DOOR
Fire and smoke are extremely dangerous hence, as soon as a fire breaks out in a room the smoke protection doors, which are tested per DIN 18095, close automatically through the use of door closers.
A smoke protection door is tasked with preventing the entrance of smoke for as long as possible in the event of fire. They are used, for example, to separate hallways with a length of at least 30 meters as well as in stairways and hallway closures. This creates smoke-free zones and escape or emergency routes so people can leave and evacuate the respective building. Smoke protection doors must, like fire protection doors, close by themselves and be equipped with a latch lock and a circumferential seal. They can be kept open only with a specially approved hold-open device. The doors must be equipped with special locks that have a spring latch.
Technical data
A three-sided special seal and a floor seal tailored to the specific application reliably guard against smoke penetration. The smoke-proof steel door has a 62 mm thick double-leaf door element that is rebated on three sides. The door has a 1.5 mm thick corner frame, a 3-sided seal, and a lower bottom threshold for the door leaf's sliding threshold seal. The leaf and frame are galvanized and prime coated in RAL 9002. (Grey white).
