door closed and locked.
2 Remove the first secondary key (If DM2/DMS2
or more).
3 Check that the primary key is trapped in
position and the door remains locked.
4 Remove the remaining secondary key(s) (If
DM3/DMS3 or more).
5 Check that the primary key is trapped in
position and the door remains locked, upon
removal of each secondary key .
6 Insert and turn all of the secondary key(s).
7 Check that the primary key can only be
removed when all the secondary key(s)
are inserted.
8 Check that the door can be opened.
9 Ensure that when the actuator is removed
from the head, the primary key cannot be
fully turned 120 degrees.
Service and Inspection
Regular weekly inspection of the following is
necessary to ensure trouble-free, lasting
operation:
1 Secure mounting of components.
2 Debris and wear .
