8.4.3. Locks adjustment
There are two methods for adjusting the locks installed in the vent. The locks
adjustment order is irrelevant, since they operate independently.
Method 1
– lock fixture height adjustment:
The screws fixing the lock and also serving the purpose of adjustment are presented on fig.
32 - they are labelled as item "2". Adjustment may be performed
within a range of about 5
mm. After correcting the height (if necessary), tighten the screws and secure the lock from
unintended moving using a counter self-drilling screw - labelled as item "1" on figure 32.
Method 2
– adjustment of electromagnet armature fixture
After closing the armature, it should contact the electromagnet at its full area. If a situation
shown on fig. 36 occurs when the armature does not shut completely, adjust it so that the
electromagnet surfaces and the armatures lie parallel towards each other after shutting.
If the lock/locks does/do not operate correctly, the reason may be their wrong
adjustment. In such case, the adjustment works described above must be performed.
