REX Button
20 AC-A4x Installation and Programming Manual
8. REX Button
The REX button is used to open the door without the use of proximity
card or PIN code, and must be located inside the premises to be
secured. It is usually located in a convenient location, such as 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 for Fail Secure Operation. The door chime in the BL-D40
does not sound when the REX button is used to open the door.
Fail Secure Operation: From the moment the REX button is
pressed, the door remains unlocked until the Lock Strike Release
Time passes. After this time, the door is locked even if the REX
Button is not released.
Fail Safe Operation: From the moment the REX Button is pressed,
the door remains unlocked until the REX Button is released and
the Lock Strike Release Time passes. In this case, the Lock Strike
Relay only begins its countdown once the REX Button is released.
