9. STROOMPRINCIPE
9.1 WERKING RUSTSTROOM
Assume the lock is installed, wired, and set to fail safe. The door is open and the positive supply voltage is applied to the
BLUE
wire. As the door closes the ML420 senses the door approaching and activates the bolt pin to pull the door into
alignment. The Bolt Position and Door Position monitors will have changed to closed contact state as the door is closed
and secured.
To unlock the door, the voltage is removed from the
BLUE
wire. The ML420 will immediately release and will do so even
when significant load is being applied to the door. With the door now open the Bolt Position and Door Position monitors
change to open contact state. The ML420 will remain unlocked as long as the door is open but will instantly re-lock when
voltage is applied to the
BLUE
wire and the door is closed.
In the event of a power failure, the ML420 unlocks.
