7.21.4 Gamewell-FCI: CAM Text Event Holding Registers
Each of the point status holding registers is divided into an upper and lower byte as
described below.
•
Upper Byte
: The upper byte contains general status information about the point.
•
Lower Byte:
The lower byte is primarily used when bit 11 in the upper byte is a ‘1’ (or
active). When bit 11 is a ‘1’,
See “CGW-MB Active Event Code” on page 73.
for detailed
information about the active point. The lower byte will be all 0’s if the point is not in an
active state.
Specifically, the lower byte contains the actual active event for this point. An active state
is defined in this CLSS Gateway mainboard as any Fire, Security, Critical Process,
Medical, Mass Notification, or Supervisory alarm state.
