After installing the vent at its final location, and before commissioning it, protections must be
removed from both locks. To this end, first remove the lock casings by undoing the screws
fixing the casings. To do so, cut the strap and remove it. The strap cutting operation is
presented in fig. 33. After completing the above, install the lock casings back and tighten the
screws fixing the casings.

For locks equipped with electromagnet - connect the lock and prepare it for operation.
Observe the following points (to be performed for both locks):
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. 34 - 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. 34.
4) Close the vent leaf. Make sure that the lock follower (rounded element) is open as
shown on fig. 35a - 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. 35b.
