Safety interlocking company
Fortress Interlocks has added
the new E1, Extracted Key
Adaptor, to its amGard range of
modular safety gate switch
interlocks. The E1 has been designed
to ensure that the door to hazardous
machinery cannot be opened
without removing the safety key, and
the machinery cannot then be
restarted until the key is returned.
Fortress has achieved this by
designing a mechanism that traps
the actuator in the head until the key
is removed which then allows the
‘gate’ to swing over the keyhole.

While the actuator remains out of
the head, the gate remains over the
keyhole preventing the key being
returned to the lock.

E1 ensures a specific sequence of
operation and can be stacked or
combined with other adaptors; up to
five key adaptors can be used in one
configuration. E1 works with access
key and safety key adaptors, amGard
LOK or STOP bodies and is suitable
for either hinged or sliding door
applications.
