2.5.4 Wiring the Door Contact Input
To solve the problem of people “tailgating” in behind personnel using valid access protocol, the Auto Re-Lock feature is provided.
With Auto Re-Lock, a long door open time can be programmed. Auto Re-Lock overrides the main relay timer, resetting the door open
time as soon as the prox.pad unit senses that the door is open. A long door open time allows people sufficient time to carry packages
from the proximity reader/keypad to the door and open it before the timer runs out.
No programming is required to implement this feature.
After a valid access or egress, the prox.pad unit senses that the door switch is open and drops the main relay immediately. This
disengages the lock, which locks behind the person regardless of how long it takes that person to get through the door.
The door contact input is also used for the propped door and forced door features.
