Dear Customers,

We would like to inform you how the entry into force of Directive 2014/33/EU on April 20th, 2016 affects the UCM units consisting of the ASG safety gear, the D-BOX electronic device and the STAR, VEGA or QUASAR T-25 overspeed governors.

The new Directive classifies these UCM units as part of the safety system and, as such, they need to be subject to EU type certification.

Our UCM units already have this type certification issued by the accrediting organisation, TÜV Rheinland. These certifications will be updated by the same agency as EU type certificates from April 20th, 2016. Previously, the safety gear and overspeed governors included in it were also certified according to standards EN 81-20 and EN 81-50.

From this date on, the D-Box may be used only as part of one of the three UCM units, and Dynatech will issue a declaration of conformity for the UCM unit installed, as is done with other safety components.

The D-Box, as well as the safety gear and overspeed governors included in the UCM unit, may be purchased and stored separately, and the components the customer has in stock may also be used. The only requirements will be to request a declaration of conformity for the appropriate UCM when being installed in the lift, and to indicate the serial number of each component (safety gear, overspeed governor and D-Box) comprising the UCM unit.

Yours faithfully,
