Request to Exit (REX) Button
The REX button must be located inside the
premises to be secured and is used to open the
door without the use of a proximity card or PIN
code, it is usually located in a convenient
location, e.g. Inside the door or at a receptionist’s
desk. The function of the REX button depends on
whether the Lock Strike Relay is programmed for
Fail Safe Operation or Fail Secure Operation.
The door chime in the BLD40 does not sound
when the REX button is used to open the door.
1)
Fail Secure Operation : From the moment
the REX button is pressed, the door will be
unlocked until the ”Lock Strike Release
Time” has passed. After this time, the door
will be locked even if the REX button has not
been released.
2) Fail Safe Operation : From the moment the
REX button is pressed, the door will be
unlocked until the REX button is released,
plus the ”Lock Strike Release Time.” In this
case the ”Lock Strike Relay” only begins its
count down once the REX button has been
released.
