Fortress Interlocks has added the
DMSK to its DM (Door Module)
robust modular access interlock
range. The DMSK is a stainless steel
single door interlock designed for
hygienic areas and suitable for all
types of doors. Its minimal design
helps reduce dirt traps while protecting
workers from hazardous areas.

As part of an interlock system, DM
locks are used to control access to
enclosed areas until a safe condition
has been achieved. In a typical
operation sequence, the key is
inserted into the lock and turned; the
actuator is disengaged and the door
opened. The key remains trapped
until the door is closed and the
actuator re-engaged. Other sequences
are available.

The DM module benefits from a
revolutionary head design which
features a choice of 4 head rotation
angles with an adjustment of 360° at
90° increments and 2 actuator entry
points.

The head, all internal contact
components, actuators and key are
constructed using stainless steel.

Tested to over 1,000,000 operations,
the units have tamper resistant head
mechanisms, and require minimal
maintenance.
