1 air handling intelligence FIRE SFETY Fire Damper in libraries of EI 10 (v e -i o) S EN :01 EN 15650:0 Certificate of Conformity 1488-CPD-081/W EUROPEN PTENT PPLICTION EP GOLD MEDL MTP 01 FUNCTION The fire dampers are designed for buildings where in the event of a fire the affected zone should be isolated from the other zones, by among others, closing fire dampers, while the ventilation and air conditioning systems should operate normally in the other non-affected zones of the building. The performance criteria are satisfied in case of fire from inside to outside as well as outside to inside or both, respectively. PPLICTION The fire dampers installation is allowed within a duct passing through a vertical building partition or directly in vertical building partition. The most common applications of the dampers are protection of elevator shafts and ventilation ducts in garages. Blades of dampers in open position do not project beyond the damper contour of 10 mm body, which enables the damper installation just behind elbow, silencer or other component of ventilation system. Once the blades of the damper have been closed, the fire-affected zone is isolated, while fire resistance of partition wall is maintained. Closing the fire damper resulting from rise in temperature in ventilation duct above 7 C or 5 C and activation of fuse otherwise by control signal transmitted from the fire alarm control panel if damper is equipped with actuator. DESCRIPTION The fire damper consists of: - rectangular casing made of galvanized steel sheet alternatively stainless or acid proof steel, - movable damper blades made of fire resistant board, - combination of smoke and fire proof seals of damper blades, - control mechanism and optional EMS module enabling fire damper assessment with the TZ tester.

Remove the cover of the revision hole and turn the blade to open position using the handle on the blade. Set the electro-magnet keeper in such position in which its whole surface is in contact with the surface of electro-magnet. SSEMBLY OF WIT OTER COMPONENTS OF VENTILTION SYSTEM EI10(v e -i o)s fire damper has a 10 mm thick body. When the damper is closed, no movable part protrudes beyond the body contour; therefore, such components as C silencing grille, silencer, elbow may be installed directly behind the damper. INSTLLTION OF IN LIGT-WEIGT PRTITION WLLS For installation of GRYFIT fire damper with actuator in a light-weight wall prepare the opening of a width and a height of L r =L+35 [mm] and r =+15 [mm] respectively. For installation of GRYFIT fire damper with fusible link or electro-magnet in a light-weight wall, prepare the opening of a width and height of L r =L+15 [mm] and r =+15 [mm], respectively. L r =L+15 [mm] and r =+15 [mm], respectively. Insert a frame made of system profiles into the opening, and bolt light-weight walls around so prepared opening. Distribution: CIT Sp. z o.o. - ul.

Fusible link is a standard equipment of the fire damper. It breaks and closes isolating partition once the temperature in ventilation duct has exceeded 7 C or 5 C. In case of response or damage of fusible link, replace it with the new one prior to re-opening the isolating partition of the damper. Procedure of fusible link replacement is provided in a separate manual. WIT FUSIBLE LINK, ELECTRO-MGNET ND MICROSWITCES The GRYFIT fire damper optionally equipped with mictroswitches and electro-magnet does not have actuator compartment. Dampers in this version have the same dimensions as the dimensions of the fusible link fire dampers. In case of assembly with TR grille at the end of ventilation duct, TR grille has the same dimensions of L [mm], [mm], L k [mm], and k [mm] as the dimensions of the TR grille for GRYFIT fusible-link fire dampers.
