Integrated switch function

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 then 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.

Therefore using the XMR,
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.
