Escape route
October 1st 2009 The new DM-I Door interlock from
Fortress Interlocks features an
internal release mechanism allowing
exit from a dangerous area even
when the door is locked.
The DM unit is mounted on the
outside of the guard allowing normal
entry and exit using a Fortress Key.
The unit is fitted to the doorpost and
allows operators to enter through one
access point and exit through another
in multi-access applications. The
DM-I features a large red button and
depressing the button releases the
door, even though the DM unit is still
locked. The action also breaks dual
safety circuits wired to the safety
system of the machine to ensure it
stops. Once the operator has exited,
the machine cannot restart until the
DM-I has been reset. More articles from Fortress Interlocks Ltd: |
