delay intervals within each possible setting. Access control units are preset with a
time delay of approximately 10 seconds by Eberline during manufacture. This 10
sec. default interval has been determined to be effective for providing sufficient
time to allow the user to exit the unit without allowing potential tailgating of other
users behind the first. In short, it allows the exit gate to lock relatively quickly
after the user has exited the unit. The time delay can be adjusted by the customer
to support the potential for specific exit gate unlock time intervals other than the
noted factory setting. The table of the time delay intervals and the corresponding
switch settings, printed on the side of the relay module itself, is shown in Figure
17.1. Power to the access control unit should be turned off prior to resetting the
time delay relay.
