or for Fail Secure Operation. The door chime in the BL-D40 does not
sound when the REX button is used to open the door.

pressed, the door remains 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 remains unlocked until the REX Button is released and

Case and Back Tampers
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 external sounder, a PS-C16/17 power supply, or
another compatible device. One of these devices then activates a
siren, and if available, a strobe light. The siren time can be easily
programmed in the unit from 0 to 9 minutes.
You can clear a tamper event by entering a valid User or Open code
to open the Lock Strike Output in the current mode of operation. For
example, while in Secure mode, you cannot use the Open code to
clear the tamper event, because the Open code does not work in
Secure mode. However, you can apply a Master code or Secure code
to clear the tamper event in Secure mode.
