In Figure 53, the PHS, S/N 341 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 53, 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 54 on page 153
shows that both the IPHS and the PHS detectors retain their old S/N to address correlations while the circuit is
mapping. Mapping activity is indicated on the control panel LCD screen. If the control panel is connected to the
computer running the VM-CU, the Current Status tab on the V-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 VM-CU configuration utility.
Figure 54: Both detectors returned to new locations
(1) PHS, S/N 34-1 detector returned to service in new location before remapping
(2) IPHS, S/N 33-1 detector returned to service in new location before remapping
Figure 55 shows the map after remapping. Note that the new S/N-to-panel address correlations have been made.
The IPHS detector is now correlated with address 102 and the PHS detector is correlated with address 101. The
relocated devices will now respond as programmed for the original address location.
