Request to Exit (REX) Button
Case and Back Tamper
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. The door chime in the BL-D40
does not sound when the REX button is used to open the door.
1)
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.
2)
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. This feature is designed to keep the
door open when used in conjunction with fire sytems.
If the case of the controller is opened or the controller is removed
from the wall, a tamper event is triggered and a coded tamper
signal is sent to a BL-D40, Supply, or other compatible device.
If the BL-D40 External Sounder receives a Tamper Event Signal, it
will activate a Siren and a Strobe Light. The Siren time can be
easily programmed in the AC-F43 from 0 to 9 minutes.
The tamper event can activate the Auxiliary Output if the controller
is in Auxiliary Mode 3. Refer to "Setting the Auxiliary Mode" on
Page 27.
Clearing a tamper event is done by entering a valid User Code.

BL-D40 External Sounder
The BL-D40 External Sounder is designed to operate indoors and
installed within the premises to be secured. The Sounder can be
powered by 12 to 24V DC power supply or by 16 to 24V AC from a
transformer.
The BL-D40 is capable of emitting four different types of alerts both
audible and visual; Bell, Door Chime, Siren, and Strobe Light.
1)
The Bell always sounds when the controller's doorbell button
is pressed.
2)
The Door Chime can be programmed to sound whenever a
valid code is entered.
3)
The Siren can be programmed to sound when the case of the
controller is tampered i.e. opened or when the controller is
removed from the wall. The controller can also program the
length of the Siren Time in the BL-D40.
The Controller communicates with the BL-D40 using a coded
proprietary Rosslare communications protocol. This provides a
more secure link between the Controller and the BL-D40.
If the BL-D40 receives any unrecognized codes on its
communication line or communication between the controller and
the BL-D40 are severed, the Strobe with flash repeatedly until the
communication problem has been resolved.
