If the devices are returned to different locations, the map supervision function
recognizes that previously mapped serial numbers occupy new map locations.
When the mapping supervision function recognizes the need to remap the loop,
the panel is put in the map pending state. In the map pending state, the panel
automatically remaps the loop when the quantity of reinstalled devices is equal to
or greater than the quantity of devices defined in the original map. If the control
panel is connected to the computer running the 3-SDU, the Current Status tab on
the Signature Series Status / Diagnostics window indicates Mapping Pending.
In Figure 56, the PHS, S/N 34-1 detector originally installed at address 102 has
been installed in the location originally occupied by the IPHS, S/N 33-1 detector.

Until all devices are returned on the loop and the loop automatically remaps, the
original S/N-to-panel address correlation is still valid. Figure 56, shows that the
device address moves with the detector until the loop is remapped. In this
example, relocating the PHS detector temporarily relocated address 102. Until all
devices are returned and the loop remapped, testing a relocated detector will
cause the panel to respond as though the detector was still installed in its original
location.
During mapping, all devices remain operational and are capable of initiating an
alarm. Figure 57 on page 207 shows that both the IPHS and the PHS detectors
retain their old S/N-to-panel address correlations while the loop is mapping.
Mapping activity is indicated on the control panel LCD screen. If the control panel
is connected to the computer running the 3-SDU, the Current Status table on the
Signature Series Status / Diagnostics window indicates Mapping in Progress.
Once mapped, the mapping supervision function automatically correlates a panel
address to a specific map location until manually changed using the SDU
configuration utility.
