Inactive door can be locked automatically when the active door is closed. Inactive door can be quickly opened when the active door is opened.

■  Install  AFB02  to  the  inactive  door,  then  the inactive  door  will  be  automatically  locked  when the active door is closed.
When  the  active  door  is  opened,  the  AFB02  upper  and 
lower  deadbolts  will  automatically  retract  and  unlock  the 
inactive door. When the active door is closed, the deadbolts 
automatically protrude and lock the inactive door.
■  Suitable for emergency exits
During  the  locked  position,  the  inactive  door  can  remain 
locked  even  when  it  catches  the  side  force(*)  of  6,000  N.  
And  even  strong  side  force  falls  on  the  inactive  door    such as in an emergency, just after the active door is opened, the AFB02's deadbolts retract to open the inactive door.
*The pressure directly falls on a deadbolt: (When the upper 
and lower clearance is 6mm each).
