Internal Case and Back Tamper
If the unit is forcibly opened or it is removed from the wall, a tamper
event is triggered. A tamper output opens sending a to the connected
Alarm system (purple wire) the event closes when the tamper is closed
(case is re-closed or re-attached to the wall).
The tamper event can also activate the auxiliary output if the
controller is in Auxiliary Mode 3 (see Table 5).

Lockout Feature (Keypad/Card Tamper)
If the controller is presented with wrong codes (PIN or card)
consecutively several times, the unit goes into Lockout mode.
When a lockout occurs, the controller’s reader and keypad are de-
activated so no codes can be entered until the set lockout period
expires.
During Lockout mode, the left LED is Off, the right LED flashes red,
and the controller beeps every two seconds.

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.
