2.5.2 Additional Relay Off-Line Function
Default value is 0.
This programming sequence sets how the remote RS-485 devices connected to the 1838 Access
Plus will behave if RS-485 communication to the device fails.
Entering a 1 in step 2 sets the remote device to grant access to any five-digit card, transmitter or
access code, whether it has been programmed into the system or not, if RS-485 communication fails.
Entering a 0 in step 2 means that access will not be granted at the device if RS-485 communication
fails. In this case, the 1838 Access Plus and any other remote devices may still be operating
normally as along as they have a good RS 485 communication link.
