After installing the vent in its final location, and before commissioning it, the lock safety
must be removed. To this end, first remove the lock casing by undoing the screws fixing
the casing. To do so, cut the strap and remove it. The strap cutting operation is presented
in fig. 35. After completing the above, install the lock casing back and tighten the screws
fixing the casing.
Fig. 35 Cable strap cutting operation for removing the lock protection
For locks equipped with electromagnet - connect the lock and prepare it for operation.
Observe the following points:
1) After connecting the electromagnet to power supply cables, lay them in such way
that they do not collide with the moving parts of the lock - the full range of the
mechanisms movement must be taken into consideration.
2) For electromagnets triggered by power decay - first, turn power supply on and only
then close the armature; the closing method is presented on fig. 36 - the armature
is shown as item "1".
3) For electromagnets triggered by electric impulse (current flow) - after completing
point 1, close the armature as shown on fig. 36.
4) Close the vent leaf. Make sure that the lock follower (rounded element) is open as
shown on fig. 37a - the follower is shown as item 2. When shutting the vent, a
characteristic "latching" sound should be heard from the lock. If the shutting
process has been completed correctly, the lock follower should be shut as shown
on fig. 37b.
