Locking
The internal motor will lock Knox when supplied with 24 VDC, with pin-3 as the positive pole (+) and pin-4 as the
negative pole (-).
The locking signals must be applied for at least 2 seconds or until the dynamic output signal from the Eden sensor
is active. There is no maximum time limit; the locking signals may be applied continuously during the time Knox is
locked.
Unlocking
The internal motor will unlock Knox when supplied with 24 VDC, with pin-3 as the negative pole (-) and pin-4 as the
positive pole (+).
The unlocking signals must be applied for at least 2 seconds. There is no maximum time limit; the unlocking signals
may be applied continuously during the time Knox is unlocked.
NB: Knox 2A will retain its locked/unlocked state when power is cut off.
Warning! All information output signals are non-failsafe and must therefore never be used to control a safety
application. To control a safety application the safe dynamic signals from Eden must be used to determine if a door
is locked or not.
Warning! The system must be connected using a fuse of max 6A.
