Spare Addresses for use as internal points on an SCU 1284 dual channel

Issue

Spare Addresses for use as internal points on an SCU 1284 dual channel

Environment

I/NET

SCU1284 dual address mode

Cause

Creating internal points can potentially prevent future hardware additions

Resolution

When an SCU 1284 is set to dual channel is only uses 12 inputs, 8 outputs and 4 reader points.  Here is a list of all software points and there uses:

XX00 DI - XX03 DI Hardware Inputs used by doors
XX04 DI - XX07 DI Spare Hardware Inputs
XX08 DI & XX09 DI SCU tamper and power monitoring points
XX00 DO - XX03 DO Hardware Outputs
XX04 DO - XX07 DO Spare software only points
XX08 DO & XX09 DO Reader Points
YY00 DI - YY03 DI Hardware Inputs used by doors
YY04 DI - YY09 DI Spare software only points
YY00 DO - YY03 DO Hardware Outputs
YY04 DO - YY07 DO Spare software only points
YY08 DO & YY09 DO Reader Points

NOTE - In most cases it is inadvisable to use every available address on a subLAN. Any address set to "Internal" in the MCU configuration can be used for internal software points.  It is important to note that this will prevent expanding the subLAN to use these addresses in the future.
