Η εταιρεία NADI Α.Ε. ιδρύθηκε στη Θεσσαλονίκη το 1978 και δραστηριοποιήθηκε τα πρώτα χρόνια στους τηλεχειρισμούς και διαφόρων ειδών αυτοματισμούς.Από το 1981 οι δραστηριότητες της εταιρείας επεκτάθηκαν στην εισαγωγή και εγκατάσταση μηχανισμών για αυλόπορτες, γκαραζόπορτες, βιομηχανικές πόρτες, πόρτες ταχείας λειτουργίας καθώς και συστημάτων φόρτωσης.
The BS 8524 compliant FireMaster active fire curtain barrier has been developed to work with all building types, including domestic houses and is supplied with the Coopers Total Gravity Fail Safe (TGFS) system and features variable speed, controlled descent, limits radiation, smoke leakage, emergency egress and side channels.
Available in unlimited widths and drops up to 8 meters and with fixing options to suit all types of ceiling configurations, the FireMaster active fire curtain barrier can be integrated with both solid and suspended ceilings and will remain hidden within the ceiling until deployed.
The FireMaster active fire curtain barrier is a vertical fire curtain barrier compliant to BS 8524 Part 1 for single and overlapping curtains and BS EN 1634-1 and provides 180 minutes integrity. The FireMaster fire curtain can also offer smoke control and is compliant to BS EN 1634-3.
Integrity (E) is the ability of a test specimen of a separating element of building construction, when exposed to fire on one side, to prevent the passage through it of flames and hot gases and to prevent the occurrence of flames on the unexposed side. The requirements are the following:
– cracks or gaps of certain dimensions
– ignition of a cotton wool pad
– sustained flaming on the unexposed side
Radiation Control (EW)
Radiation Control maintains all the integrity performance of Integrity (E) when exposed to fire on one side, and also provides some heat resistance. The classification shall be given by the time for which the maximum value of radiation, measured as specified in the test standard, does not exceed a value of 15kW/m2.
Insulation (EI) is the ability of a test specimen of a separating element of building construction, when exposed to fire on one side, to restrict the temperature rise of the unexposed face to below specified levels.
Smoke Control (Sa)
Smoke Control (Sa) or smoke leakage is the ability of an element of construction to reduce the passage of hot and/or cold gases or smoke from one side of the element to the other to below specified levels.
