Industrial safety specialist, Fortress
Interlocks, has introduced an
ATEX Certified, explosion
protected safety switch key station.

The CPS4STOPXP key station is
designed to release keys used to
control mechanical door locks that
provide access to machinery and
process lines operating in potentially
explosive environments. Both the
switch and the door locks are suitable
for use in Zone 1 and 2 environments
and the electrical parts are ingress
protected to IP67.

The station is available with a
maximum of five safety key adaptors.

By turning the first key the machine is
isolated and the other four keys are
released. These keys can be used to
open a maximum of five ATEX
Certified ‘DM’ mechanical door locks
that give access to the safeguarded
area. Restarting the machine is only
possible when all keys are back in the
key control station.

This interlocking system complies
with the ATEX Directive, meeting the
European Hazardous Location
Designation: EExd IIC T6 category
