Circular fire damper cartridge with a finishing valve and collar for installation in a fire resistant suspended ceiling. Connection to a
ventilation system with flexible duct. For installation in fire-resistant EI30 and EI60 ceilings. The circular fire damper cartridges are
equipped with a fusible link that holds the two parts of the blade in the open position. When the temperature in the duct rises above
72°C, the fusible link melts and releases the two blades. The damper is now closed and two blocking hooks keep the blades in their
safety position, which prevents any smoke or flames from passing through.

Storage and handling
Storage and handling
As this product is a safety element, it should be stored and handled with care.
Avoid:
• any kind of impact or damage
• contact with water
• deformation of the casing
Installation
General points
∎The installation must comply with the installation manual.
∎Verify if the blades can move freely.
∎Direction of the airflow: discretionary
∎SC-S fire damper cartridges are tested in standardised fire resistant suspended ceilings in accordance with EN 1366-2 and
EN 1364-2.
∎The fire damper cartridge must remain accessible for inspection and maintenance.
∎Please observe safety distances with respect to other construction elements.

1. Build the fire resistant suspended ceiling according to the
manufacturer’s instructions. Provide a piece a flexible duct to
connect the ventilation duct to the SC-S.

2. Make a round opening in the fire resistant suspended ceiling,
with diameter as indicated in the table.

3. Arm the fire damper cartridge as explained in the operating
instructions. Pull the flexible duct through the opening and
place it over the connection provided for the ventilation duct.
Attach the duct to the SC-S in an airtight manner.
Caution: Make sure that the damper blades are in open
position before installing into the ceiling.

4. Press the retaining springs against the cylinder and slide the
SC-S in the opening. Push the SC-S all the way into the opening
so that the retaining springs lock above the ceiling.

6. Finally, install the finishing valve and adjust according to the
desired flow rate.
The use of another plastic finishing valve is permitted, as
long as it does not interfere with the operation of the damper
blades.
Maintenance
∎No specific maintenance required.
∎Schedule at least 2 visual checks each year.
∎Remove dust and all other particles before use.
∎Follow local maintenance regulations (i.e. BS9999 Annex V; NF S 61-933) and EN13306.
∎Warning: butterfly dampers, in their closed position, can move in the duct when placed under too high pressure.
