4.7 REX Function
The REX button is connected to Rosslare’s secured intelligent
power supply. 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, 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 Fail Secure Operation.
Fail Secure OperationFrom the moment the REX button is
pressed, the door is 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 OperationFrom the moment the REX button is
pressed, the door is 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 is
released.
4.8 Secured Intelligent Power Supply
Rosslare’s secured intelligent power supplies are designed for use
with Rosslare's secured standalone access control units, including
the AYC-Ex5/T65 series. The units are designed to operate indoors
and are installed within the secured premises. The units must be
used with one of Rosslare’s secured intelligent power supplies,
which provides Lock Strike output and REX input. The AYC-Ex5/T65
and the power supply communicate through a proprietary Rosslare
protocol, which provides a secure link between them. This in turn
activates the door lock.
Each power supply unit contains a speaker connection for all
sounder abilities.
