Emergency release for personnel in
danger areas
The new MLQ Emergency Release Interlock utilises a conventional crash bar door lock which instantly overrides the interlock mechanism, opening an escape route
Trapped key interlocks are an invaluable way of controlling access to potentially hazardous areas, but a critical failure of safety procedure could leave an operative locked inside a protected zone in serious danger of injury or death It is therefore essential that the interlock can be overridden in an emergency; it is also essential that any override mechanism should be mechanical, as electrical devices may not work in the event of a fire or power failure

Interlock avoids possibility of trapping staff
An interlock system has been developed to prevent personnel from becoming trapped in potentially hazardous areas such as automatic warehouses, cold stores, industrial boiler filters and X-ray cells
The new MLQ Emergency Release Interlock from Mistura Systems caters for such a worst-case scenario.
Located inside the guarded area, it utilises a conventional crash bar door lock which instantly overrides the interlock mechanism, opening an escape route.
Machinery within the protected area can only be started when the access door is fully closed and locked.
In the unlikely event of someone remaining trapped inside when the machinery starts, they simply hit the crash bar to override the interlock mechanism and open the door.
Five versions of the MLQ are available, incorporating personnel/supervisor keys, manual or auto reset, and signal switches to interface with PLC controls.
