6.7 Request to Exit (REX) Function
The REX Button is connected to Rosslares’ secure application
appurtenance. The REX Button must be located inside the
premises to be secured and is used to open the door without the
use of a 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.
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.
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.
6.8 Secure Application Appurtenances
Rosslares’ secure application appurtenances are designed for use
with Rosslare's secured series stand alone access control units,
including AYC-FX4/AYC-GX4. It is designed to operate indoors and
installed within the secured premises. The AYC-FX4/AYC-GX4 must
be used with one of Rosslares’ secure application appurtenances,
which provide Lock Strike output and Request to Exit (REX) Input.
Both units communicate through a proprietary Rosslare protocol,
which provides a secure link between the AYC-FX4/AYC-GX4 and
the appurtenances. This in turn activates the door lock.
The units also function as the power supply for the AYC-FX4/AYC-
GX4; they also contain a speaker connection for all sounder
abilities.
For more information see the specific Appurtenances Manual.
