Inverted Follow and Test Output

Inverted Follow and Test Output: This mode can be used when the state of the door is required to do the opposite of the checked output. This is the same as the Follow and Test Output function, however, the output is inverted (NOT).

• If the checked output turns on, the controlled door/door group locks (or clears the lock down). If the checked output turns off, the controlled door/door group unlocks (or locks down).

In between state changes, the door/door group's state is continually tested at approximately 30 second intervals. When the controlled door/door group's state is changed by an external operation, the programmable function restores it within 30 seconds.
