Figure 8-11: Detectors removed for service
If these devices are returned to their original locations, as shown
in Figure 8-12, the map supervision function recognizes the
detectors have been returned as originally installed (and
mapped), and takes no additional action.

Figure 8-12: Detectors returned to service in original locations
If the devices are returned to the Signature Data Circuit but are
not returned to their original locations, the map supervision
function recognizes that previously mapped serial numbers
occupy new map locations. Once the mapping supervision
function has recognized the need to re-map the circuit, the panel
is put in the “map pending” state. Once in the map pending state,
the panel will automatically re-map the circuit when the quantity
of devices re-installed on the circuit is equal to or greater than
the quantity of devices defined in the original map. If the panel
were connected to a computer running the SDU Program, the
DSDC status function would indicate map pending.
