From the moment the REX button is pressed, the door is
unlocked until the REX button is released. In this case, the
Lock Strike relay only begins its countdown once the REX
button is released. This feature is designed to keep the door
open, when used in conjunction with fire systems.

Tamper Feature
If 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 external sounder.
If the BL-D40 receives a tamper event signal, it activates 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 (see Table 3).
4.7
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 keypad and reader 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.
