INSTALLATION

Install as tested

01Install as the tested specimenThe damper only achieves its fire rating when installed as tested. Follow the installation instructions in the product file and the approved design.
02Handling and storageReceive and store in a dry place · Wear protective gloves · Do not step or climb on · Do not drop, roll, tip or drag
03Maintenance every 6 monthsCheck power supply, test closing/opening by actuator and by hand, clean blade and seals, record in the maintenance log. Provide an access door to reach the damper.

As in the S-MFSD-L210 catalogue; see the Installation section of each model's catalogue.

DECLARATION SCOPE

Measured, calculated and in progress

EI classEI class is stated from the fire test report, with the report number; the declaration of performance (DoP) lists only measured and certified values.
Pressure drop and closed leakagePressure drop and leakage are calculated reference values for design and are outside the ISO 21925-1 fire certification scope. They will be replaced by measured data from extended testing when available.
Dampers larger than the specimenSplit into several dampers following each model's rule; the selector shows the number of dampers and each damper's size.
S-MFD-FS-L400 · EN 1366-2A 600 × 600 × 400 mm specimen with its actuator and enclosure was fire tested to EN 1366-2 and ISO 21925-1 at a laboratory in Guangzhou, China, achieving EI 180. Pressure drop and leakage were measured internally by Starduct on 180 × 180 and 600 × 600 samples.

SELECTION

Four steps to select a fire damper

01EI class and actuationChoose the model by the EI class required for the fire wall or floor and by actuation: actuator or fusible link.
02SizeEnter the clear W × H; dampers larger than the specimen are split by the model's rule.
03Pressure drop, leakageChoose size and velocity to see airflow, pressure drop and closed leakage. Charts and lookup table update with your selection. Recommended velocity for ducts with fire dampers: 3–8 m/s.
04SubmitAdd to the project list, print the submittal with the issued DoP; export CSV / JSON for the BOQ.
