3.4.2 Request to Exit (REX)
A REX push button may be located within the premises and used to
open the door from the inside. It is usually located in a convenient
location (e.g. next to the door at the receptionist’s desk). The function
of the REX depends on the Lock relay, and wether it is programmed for
fail-safe or fail-secure operation.
Fail-Secure Operation: from the moment the REX is depressed, the
door will be unlocked until the Lock release time has elapsed. After this
time, the door will be locked, even if the REX has not been released.
Fail-Safe Operation: from the moment the REX push button is
depressed, the door will be unlocked until the REX is released. In this
case, the Lock relay only begins its countdown once the REX has been
released. This feature is designed to keep the door open, when used in
conjunctionwithresystems.
