Double door interlock

regulates access in hygienic areas

Fortress Interlocks Europe

Fortress Interlocks has introduced the robust DMSK2 into its DM (Door Module) access interlock range. The standalone, stainless steel, double door interlock is designed for hygienic areas and suitable for all types of doors. Its minimal, smooth design helps reduce dirt traps while protecting workers from hazardous areas. It is suited for use in the food industry and any applications requiring hygienic processes.

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. The DMSK2 double door interlock allows up to two trap keys.

The DM module benefits from a 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 keys are constructed using stainless steel. Tested to over 1,000,000 operations, the units have tamper resistant head mechanisms, and require minimal maintenance.
