Standards and guidelines

German 'Bau- und Prüfgrundsätze' [Principles of Construction and Testing], 2/84 edition
Maintenance standards DIN 31051 and EN 13305

Maintenance

Smoke protection dampers and duct smoke detectors must be maintained regularly and must be operational at all times
To maintain the normal function of the unit, or to re-instate its normal function, maintenance standards DIN 31051 and EN 13305 must be complied with
Smoke protection dampers must be maintained at least every 12 months
A maintenance report must be created; documents must be kept for reference
Maintenance-free as construction and materials are not subject to wear

Functional description

Smoke protection dampers with external linkage have opposed action blades.

An external linkage transfers the synchronous rotational movement from the drive arm to the individual blades.

Even large dampers can be safely opened and closed with this type of linkage.

Opposed action blades close at different speeds since the linkage includes a transverse link.

This facilitates the closing process and reduces the closed blade air leakage.
