Fortress Interlocks, of Erlanger, Ky., has launched Door Module
(DM), a modular access interlock suitable for use on all types
of doors. The unit, part of Fortress' new mGard range of modular
interlocks, is available with a selection of all stainless steel
actuators suitable for both hinged and sliding doors.
The units have tamper-resistant head mechanisms and require minimal
maintenance, according to company information. The head features
a choice of four-head rotation angles and two actuator-entry points.
DM is available as a single door lock or with up to ten multiple
access lock modules. A system using DM can be expanded at any
time with the addition of more modules or trimmed down and the
surplus modules used elsewhere.
