DM2-10 / DMS2-5
(Multiple Units) -
The
primary key is trapped in the lock, while the
actuator is trapped in the head. The
secondary key(s) can then be inserted and
turned, allowing the primary key to be
removed. The actuator is then disengaged to
allow the opening of the door . The primary key
cannot be re-inserted until the door is closed
and the actuator is re-engaged. The
secondary key(s) remain trapped until the
primary key is replaced.
The multiple lock
units offer variable key exchange sequences
which require that either extra keys be
inserted, or removed before the door can be
opened or that extra keys are inserted or
released once the door is open.

is a robust, modular
access interlock suitable for use on all types of
doors. It is available as a single or multiple door
interlock with up to ten locks. The DM comprises
two p arts, a lock body and an actuator . The
Lock body is modular in construction whilst the
Actuator is available in three variants to cater
for a wide variety of applications. This product
is also available in full stainless steel (
DMS
)
Part of an interlock system, the locks are used
to control access to enclosed areas until a safe
condition has been achieved.
DM/DMS
is available with a choice of
3
Actuators:
•DM-F
- a fixed actuator that is supplied as

- a hand operated actuator available as
an optional extra.
DM
may be surface or panel mounted using the
optional M-BOB Adaptor.
DMS
is only surface
mounted.
DM
is available with a choice of CL
or ML lock mechanisms. All CL / ML locks can

Tools and Fixings Required
2 off Cap head / hexagonal head bolts for each
module.
Front of Board mounting:
M6 x 25 or ¼” x 1"
Back of Board mounting:
M6 x 55 or ¼” x 2¼”
Suitable driver for above.
If using through holes:
•
1 off Drill Ø6.5 (or Ø5/16").
•
2 off M6 (or ¼”) Full nuts per module.
If using threaded holes:
•
1 off Drill Ø5 (or Pilot Drill for chosen ¼”
Thread).
•
1 off M6 (or ¼”) Tap and wrench.
Mounting
Mount this unit well away from sources of
vibration or use anti-vibration mountings in
order to avoid the effects of vibration, shock
and bump.
Mount the unit only in its correctly assembled
condition to flat steel plate of minimum thickness
3.0mm or 6.0mm if aluminum. The product must
be mounted in such a way as to ensure that the
gap around the perimeter of the guard, when
closed, does not exceed the limits specified in
En294 & En953.
The head can be turned in 90 degree increments
to suit a variety of mounting and handing
configurations. It can also be adjusted by 5
degrees in either direction, from the nominal
position for small radii hinged doors.
To rot ate the head through 90 degrees
increments:
1 Remove the two head adjustment screws
(See Fig 1- Head Adjustment).
2 Rotate the head to the desired position.
3 Refit the two head adjustment screws.
DM/DMS
can be mounted in any orientation,
observing the following rules:
1 Locate the unit so that all the locks are
within easy reach.
2 Ensure that the head adjustment screws
are accessible when the unit is
mounted.
3 Choose the correct mounting
configuration for the size and type of door
(See Fig Y).
4 Mount the unit to the panel using the
chosen fixings.
5 Tighten the fixings to a Torque of 8 to
10Nm (5.9 to 7.4 lbf.ft).
6 All fixing screws must be permanently
prevented from removal, either by
vibration or by personnel using standard
tools.
7 Loosen the head adjustment screws,
without removing them.
8 Angle the head to suit the door .
9 Carefully tighten the screws, ensuring
the position is not changed.
All fixings must be used.
Standard Functionality
DM1/DMS1
(Single Module)
-
The key is inserted
into the lock and turned, while the actuator is
trapped in the head. The actuator is released
allowing the door to be opened. The key
remains trapped until the door is closed
and the actuator is re-engaged.

Sequencing
The DM/DMS system is extremely flexible in terms
of its sequencing possibilities. Two types of
operation are possible. These are used
individually or mixed to provide complex
operation. The two types of operation are:
Sequential Operation
This is when the key in the module interacts
only with its neighboring modules. This dictates
the order in which keys are inserted and
removed.
Non-Sequential Operation
This is when two or more keys work together
in a group. In a non-sequential system, any of
the keys in the group can be operated together.
Therefore, the order in which keys are inserted
or removed from the group is not dictated.
However, all of the keys in the group must be
either all inserted and trapped or all removed.
The DM/DMS sequence should have been
specified at the purchasing stage. If the
sequence needs to be changed, contact
Fortress Interlocks.
