Modular access interlock suits all door types

A robust modular access interlock, suitable for use on all types of doors, control access to enclosed areas until a safe condition has been achieved.

Fortress has launched DM (door module), a robust modular access interlock suitable for use on all types of doors.

The unit is sold as a single or multiple door interlock with up to ten multiple access locks available.

DM marks the first phase of the launch of the new modular KeyGard trapped key interlocks.

As part of an interlock system, the 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.

DM has a die-cast zinc body with pearl bronze finish.

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.

In conjunction with DM, Fortress Interlocks has launched the XM, a modular mechanical key exchange that is used to exchange one or more keys for a number of other keys.

The device forms the link between isolation devices and access locks.

Any combination of isolation/access keys is possible.
