Understanding Signature data loops
Operation
The advanced features of the Signature controller module perform a number of
advanced operations. These operations are not always apparent from the control
panel. Table 59 lists a number of Signature data loop conditions and describes
the loop’s operational responses.

When you:
Response
Remove a detector
, and then
r
einstall the detector in the
same base
• A system trouble displays on the LCD screen when the
detector is removed. The message shows the detector’s
label or address.
• The system restores when the detector is reinstalled.
Remove a module or pull
station
, and then reinstall the
module/pull station in th
e same
location
• A system trouble displays on the LCD screen when the
module/pull station is removed. The message shows the
device’s label or address.
• The system restores when the module/pull station is
reinstalled.
Remove a detector
, and then
i
nstall a different detector of the
same type in the same base
• A system trouble displays on the LCD screen when the
detector is removed. The message shows the detector’s
label or address.
• The Signature loop controller remaps the loop
, replacing the
serial number of the old detector with the serial number of
the new detector, when mapping is enabled. All of the old
detector’s sensitivity and verification settings are transferred
to the new detector. The system returns to normal when
mapping is finished.
• The communication fault for the old detector remains
, when
mapping is disabled.
Remove a module or pull
station
, and then reinstall a
different module/pull station of
the same type in the same
location.
Note:
A SIGA-UM replacement
module must have jumper JP1
se
t in the same position as the
original module.
• A system trouble displays on the LCD screen when the
module/pull station is removed. The message shows the
device’s station label or address.
• The Signature loop controller remaps the loop
, replacing the
se
rial number of the old device with the serial number of the
new device, when mapping is enabled. If the devices are
modules (not pull stations), the old module’s personality
codes are transferred to the new module. The system
returns to normal when mapping is finished.
• The communication fault for the old detector remains
, when
mapping is disabled.
