Knox - double safety lock
Knox is a double lock that complies with the highest safety level
(two lock cylinders with monitored positions) that can be used both
as a safety and process lock. The locking function is electrically
controlledand isbi-stable, i.e. it retains itsposition (unlocked/locked)
in the event of a power failure. Dual signal for unlocking is safe at
both short-circuits and cable breaks.
The handles operate as they would on a normal door but the
exterior handle also have a reset function, why a separate reset
Knox is easy to assemble,
adjust and dismantle in and
out of the T-slot of the Quick-
Guard fencing system.
