2 Series FSD-FLD FSD-B-U / FSD-A-U Fire and smoke dampers. UL Approval Description The FSD-B-U and FSD-A-U models are 3V type multi-blade fire and smoke dampers approved according to UL standards (UL555 and UL555S). Fire dampers close automatically to prevent fire and smoke from spreading to adjacent fire compartments through HVAC ventilation ductwork. The dampers are approved to withstand fire conditions for 90 minutes according to UL555 standard. The FSD-B-U model achieves Class 1 leakage level according to UL555S at a temperature of 177 C. The FSD-A-U model achieves Class 3 leakage level according to UL555S at a temperature of 177 C. FSD-A-U The FSD-B-U model fire damper incorporates elastomeric airtight seals along the edges of the closing blades. The casings or frames of the dampers are manufactured with reinforced corners. Where height H <425 mm, low profile lines are used at the top and bottom of the frame. The blades are reinforced with 3 lengthways structural sections called Vee s to provide them with greater rigidity and resistance. Silicone sealant is applied to the joint between the frame and its enclosure to prevent any air or smoke leakage. An inspection hatch is required in the ductwork adjacent to the damper to facilitate periodic inspection and maintenance. The FSD-B-U / FSD-A-U models are installed vertically with the blades in a horizontal position, regardless of the direction of the horizontal air flow. FSD-A-U

Series FSD-FLD 5 FSD-B-U / FSD-A-U Fire and smoke dampers. UL Approval Operation: The FSD-B-U and FSD-A-U models are designed to be fail-safe, allowing the dampers to automatically return to the desired position in the event of a fire and smoke. The damper operates (closes) if the power supply of 24 V (optionally 230 V) to the servomotor is interrupted, whether as a result of a system failure, a command from the control system or by the thermoelectric fusible link when the temperature exceeds 74º C. The damper is open while power is supplied. The damper automatically resets (opens) when 24 V (optionally 230 V) is supplied to the servomotor. If the damper is closed due to high temperatures, i.e. by the thermoelectric fusible link, it is manually reset by a button installed on the damper. Remote damper status indication (limit switch) is also available. Installation: The dampers are designed for the lowest possible pressure drop. The technical department deals with each order individually and supplies the client with a blade width for the desired height and ensures that the dampers have the greatest free area when open and, therefore, the lowest pressure drop. Blade width may therefore differ and can protrude outside the damper frame on one or more sides, up to a maximum of 69 mm.

6 Series FSD-FLD Fire dampers with fusible link, FLD-S-U / FLD-S-UD. Approval UL Description The fire dampers are approved to withstand fire conditions for 90 minutes (1.5 hours) in accordance with UL555. They are 3V type multi-blade operated by the melting of a fusible link calibrated to 74º C. Fire dampers close automatically to prevent fire from spreading to adjacent fire compartments through HVAC ventilation ductwork. The FLD-S-U model is fire rated under static conditions. The FLD-S-U model is fire rated under dynamic conditions. It is designed for system speeds of up to 10 m/s and pressure of up to 1000 Pa. FLD-S-U / FLD-S-UD Fire damper with fusible link The damper frame is constructed with reinforced corners. Frame sizes under 425 mm high use low profile thin line frames. The blades are reinforced with 3 Vee s structurally designed lengthways. The FLD-S-U / FLD-S-UD models are installed vertically, with the blades in a horizontal position, regardless of the direction of the horizontal air flow.

Series FSD-FLD 9 Fire dampers with fusible link, FLD-S-U / FLD-S-UD. Approval UL Periodic inspection, testing and maintenance The basic inspection, testing and maintenance procedures are described below. Inspection: Regular inspection, testing and maintenance are essential to ensure that the fire and smoke dampers in an installation operate as intended. Inspection and maintenance should include periodic testing of all equipment, including dampers, fans, operating devices, controls, etc. Standards such as NFPA 92A, NFPA 80, NFPA105 and local codes must be consulted for guidance with respect to the intervals of damper inspection, testing, and maintenance. The intervals of inspection, testing and maintenance vary widely depending on the system s length of operation, the condition of the air and other factors. Maintenance: Check the electric servomotor and tighten the coupling if necessary. Check the damper blades and other parts as necessary. Lubricate the latch, bearings and other moving parts with a silicone lubricant. Petroleum-based products should not be used as they may accumulate dust. Activate the damper using the electric servomotor. Check the blades to make sure they close and reopen completely. Check the damper to make sure it is perpendicular and the blade channel is not obstructed. Test: Use a moderate heat source and heat the thermal disk inside the damper. Once the required temperature has been reached, the power supply to the servomotor will be switched off and the motor spring will close the damper blades. The damper must be tested under normal air flow conditions.

We use the table on the previous page to find the following data: A L = 0,24 m 2 k p = 1,8 kdb(a)= -2 The technical data to achieve a flow rate of 3500 m 3 /h is required. Referring to the diagram above using this flow rate and the area o 0,24 m 2, we obtain a Veff of 4 m/s. With this veocity and taking into account the value of kp, we obtain: Differential pressure: 30 Pa Sound pressure level: 45 db(a) Applying L wa - db(a) = 45+ (-2) = 43 db(a)
