5.7 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 Operation – From 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 Operation – From 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.
5.8 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-F/Gx4 series. The AYC-F/Gx4 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-F/Gx4 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.
