One of the new features in the new System M+ is Latch Control. In previous blogs, FritsJurgens talked about the benefits of Damper Control and 30° Speed Control.
Latch Control can be turned on or off and is used for doors with a latch.
When you do want to use 30° Speed Control to finetune the last part of the closing movement, but you do not have a door with latch, you can simply keep Latch Control turned off.
Latch Control
Without Latch Control, a door with a latch might not have enough power to close correctly. Latch Control gives the pivot door extra speed in the last 10° of the closing movement. This new feature is therefore very suitable for exterior pivot doors. They often have to overcome drop-seals and other moist- and draft-repellant details on the way to their 0° position.
Take a look at the difference in door movement with Latch Control turned on and turned off:
This difference is also visible in our System M+ installation video:
