Double Door Interlock

Fortress Interlocks has introduced the robust DMSK2 into its DM (Door Module) access interlock range. The DMSK2 is a standalone, stainless steel, double door interlock specially 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. 

DMSK2 is ideal 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.  

With a head, all internal contact components, actuators and keys constructed using stainless steel, the DMSK2 is easy to sanitize and corrosion resistant. Tested to over 1,000,000 operations, the units have tamper resistant head mechanisms, and require minimal maintenance.
