REX Function
The REX button is located within the premises and is used to
open the door from the inside. It is usually located in a
convenient location, such as next to the door or at a
receptionist’s desk. The door chime in the BL-D40 (if enabled)
does not sound when the REX button is used to open the door.
The function of the REX button depends on the Lock Strike relay,
whether it is programmed for failsafe or for fail secure operation.
Fail Secure Operation
From the moment the REX button is pressed, the door is
unlocked until the Lock Strike Release time has elapsed. After
this time, the door is locked, even if the REX button has not
been released.
