Order details Product description Rectangular fire damper PPZEN is defined as a closure of air duct preventing passage of the fire, temperature and smoke in the place where duct penetrate through the fire separating construction. The fire damper consists of a rectangular housing, a damper blade and an actuating mechanism. The damper housing is made of a galvanized steel sheet with a thickness of 1,5 mm and lenght of 400 mm. It is divided into two parts, which are separated with frame made of fire-resistant seal. Each part consist of four sheets. The steel sheet is bent so that at the extremities of the housing flanges are formed. In all eight corners strengthening corner profiles have been inserted and clinched. Damper blade is made of high temperature-resistant, abrasion-resistant mineral material. The blade is held by axis made of stainless steel. Casing and damper blade are airtight and smoketight. The actuating mechanism of the damper is performed by an automatic thermal release mechanism (fusible link), electric actuator or solenoid actuator. Main characteristics of damper: Tested according to EN at 300 Pa Fire classified according to EN Suitable for mounting in rigid wall, flexible wall and ceiling Operating mechanism completely outside the wall - easy installation Maintenance free 330

3 Minimum dimensions Maximum dimensions B(W) x H[mm] 00 x x 800 There are possible all combinations of width and height. Standard dimensions are avaliable with pitch of 50mm. Dimensions should be avoided where there is a discrepancy between the width and height (ratio B:H 4:1). Non-standard dimensions are avaliable with pitch of 10 mm. Fire classification according to EN Rectangular fire damper PPZEN is classified according to the following combinations of performance parameters and classes: Fire resistant classification in rigid wall: EI 10 (ve, i o)s / E 10 (ve, i o)s Fire resistant classification in flexible wall: EI 90 (ve, i o)s / E 90 (ve, i o)s Fire resistant classification in ceiling: EI 60 (ho, i o)s / E 90 (ho, i o)s EI 10/90 time (min.) of meeting the requirements of integrity and insulation ve damper installed in vertical supporting construction ho damper installed in horizontal supporting construction (ceiling) i o fire can come from either direction, confirmation of meeting the requirements with the effect of fire both from inside and outside S confirmation on meeting the requirements on smoke tightness Damper is to be installed to the standard rigid wall, flexible wall and floor (ceiling) supporting construction (acc. to EN1366-; table 3, 4 and 5).

6 OPERATING MANUAL Fire damper type PPZEN-M Damper is delivered in closed position. When electric actuator is connected to the power supply damper will open. When the damper reaches the end position (damper open), in which is it blocked, the electromotor will stop. Closing fire damper takes place automatically when a power failure occurs. Thermal tripping device that comes with fire damper causes power circuit break at a temperature of 7 C (inside or outside duct). If checking is needed for proper fuctioning of fire damper, pushing the switch on the thermal tripping device will close damper. When switch on tripping device is released, the damper will open. switch for checking for proper fuctioning BLF30 BELIMO handle for manual opening Manual opening Damper can be opened without connecting to a voltage with enclosed handle turning in the direction of the arrow on electric acuator (clockwise). Damper can be locked in the desired position by fast turning back handle a quarter of a turn (counterclockwise). To unlock the electromotor, turn handle clockwise for a quarter of a turn. If the handle is released, damper will be closed by return spring. When damper is opened manually, electric actuator will not move the damper into closed position after power failure (thermoelectric fuse). Fire damper type PPZEN-R Fire damper is delivered in closed position. To open the damper, handle should be turned in counter-clockwise direction to OPEN position. Handle will be locked automatically in that position by locking device. DAMPER CLOSED DAMPER OPEN CLOSED OPEN CLOSED OPEN 334

7 OPERATING MANUAL Manual closing In order to close the damper manually, lift the handle locking device, then the torsion spring will close damper. ATTENTION! BE CAREFUL NOT TO LET THE SPRING-LOADED HANDLE HURT YOUR HAND Fire damper type PPZEN-E Fire damper is delivered in closed position. To open the damper, handle should be turned in counter-clockwise direction to OPEN position. It is possible to close damper with solenoid. The damper is opened manually. Manual damper activation is intended for periodic maintenance.
