3. If the substituted device is a nonmapping DH or DS detector, the system
automatically disables the mapping feature. As a result, a Map Fault and
Mapping Disabled monitor event is generated. You must remove the detector
and restart the panel to restore mapping operations.
Detectors
When one or more devices are removed from a Signature loop for servicing, as
shown in Figure 54, the control panel LCD screen displays a trouble condition for
each device. 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 a trouble condition. If the detector is removed from an isolator
base, the isolator will transfer.

If the devices are returned to their original locations, as shown in Figure 55, the
map supervision function recognizes the detectors have been returned as
originally installed and mapped, and no additional action is taken.
