Fail Secure Operation: from the moment the REX pushbutton is
depressed, the door will be unlocked until the Lock Strike release
time has elapsed. After this time, the door will be locked, even if
the REX pushbutton has not been released.
Failsafe Operation: from the moment the REX pushbutton is
depressed, the door will be unlocked until the REX pushbutton is
released. In this case, the Lock Strike relay only begins its
countdown once the REX pushbutton has been released. This
feature is designed to keep the door open, when used in
conjunction with fire systems.
3.4.3 Tamper Feature
In case the controller is forcibly opened or the controller is
removed from the wall, a tamper event is triggered. A tamper
signal is sent to the BL-D40.
If the BL-D40 External Sounder receives a tamper event signal, it
will activate a tamper output and a strobe light. The siren time
can be easily programmed in the controller from 0 to 9 minutes.
The tamper event can activate the auxiliary output if the
controller is in Auxiliary Mode 3. Refer to the Quick Reference
Guide for Auxiliary Mode Setting table in paragraph
4.8.2 below.
3.4.4 Lockout Feature (Keypad / Card Tamper)
In case 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 keypad and card reader
are de-activated so no codes can be entered until the preset
lockout period expires.
During Lockout, Mode LED is Off, Door LED flashes Red, and the
controller beeps every two seconds.
Refer to programming menu 6 for detailed programming of this
feature.
