Standard Operational Mode
This is the mode in which the iMXDa unit operates most of the time. When the door is closed,
and the magnet is secure the green LED will be illuminated.
Visual status is provided by green and red LEDs. The following is a description of the LED
indication when the unit is functioning.
 The green LED is illuminated when the door is closed and secure.
 Both green and red are illuminated when the system is in an alarm sequence.
 The red is illuminated when an alarm event has released the door and it is awaiting reset.
 Neither LED will be illuminated if the lock is not powered or is in bypass mode.
Bypass Mode – IRB (Or External)
Bypass mode allows a timed momentary release of the door. Bypass mode can be entered via
the onboard (IRB) key switch or an external switch. See the BDT (Bypass Delay Time)
section for a description and External Controls section for connection details. Using the
onboard key switch provides a fixed 15 second door release with automatic re-locking. During
an alarm event bypass can be used for emergency exit.
Reset – IRB (Or External)
Reset relocks the door after an alarm event. To reset manually simply turn the onboard key
switch clockwise. Reset can also be accomplished using an external switch. See the External
Controls section for connection details. This feature is not available on Chicago version.
6.1. SYSTEM FUNCTIONS
The following is a general description of the IMXDa lock system functions and DIP switch
settings. For DIP switch location see Figure 10. DIP switch setting changes are recognized at
the microprocessor when:
 Power is applied to the lock.
 During a bypass event (prior to the door being closed).
 After an alarm event (prior to reset).
For a complete illustration of DIP switch settings and their function see Figures 12A, 12B, 12C
and Table A.
