Industrial safety specialist Fortress Interlocks has integrated a key switch function into key exchange units, making it possible to isolate the power and release access keys in one operation.

The XMR unit simplifies the traditional interlock procedures for safeguarding potentially dangerous machines and areas with multiple access doors. By simply turning the first key of the XMR the safety contacts are broken, isolating the machine power. This key is then trapped and the other access keys can be used to open the door locks allowing access to the safeguarded areas. Only when all keys are returned to the XMR can the machine be restarted. This means separate key transfer between an (isolation) key switch and key exchange unit is no longer needed, providing a simplified and cost efficient solution for lots of safeguarding applications.
