SIGA-MFT Map Fault Tool Installation Sheet
Description
The SIGA-MFT Map Fault Tool is a diagnostic tool intended to
help you locate and resolve sources of mapping faults in a
Signature signaling line circuit (SLC). The SIGA-MFT ships
with these accessories:
•A USB flash drive with the SIGA-MFT Software
•A USB cable
•A 24 VDC external power supply
The SIGA-MFT is wired directly to the SLC and connected to
your PC using a USB cable and port. The SIGA-MFT simulates
the mapping operation of the panel SLC controller, and the
SIGA-MFT Software provides enhanced troubleshooting
information.
The SIGA-MFT and the Signature SLC are powered by the
USB port on your PC. An external power supply (provided) can
be connected to the SIGA-MFT when needed. For example,
when you connect to a USB hub, which does not include
power, or if communication is lost when connecting to the SLC.
Diagnostic LEDs indicate communication by flashing:
•Green = PC communication
•Red = SLC communication
Features
Figure 1 shows the connectors and indicators located on the
front face of the SIGA-MFT. Figure 2 shows the connectors
and fuse located on the back of the device.

Installation
Refer to Figure 3 when installing the SIGA-MFT.
To install the SIGA-MFT:
1. Insert the USB flash drive into any USB port on your PC,
and then double-click Setup.exe to install the SIGA-MFT
Software.
You must install the software before connecting the device
so that the PC can recognize it.
2. Connect the SLC wiring to the SIGA-MFT observing the
polarity indicated on the device.
You must disconnect the SLC from the panel, and connect
it only to the SIGA-MFT.

For Class A circuits, disconnect the Class A return wires. If
the SLC controller has a removable terminal block, simply
remove the block. The Class A return wires are not used.
3. Connect the USB cable to the SIGA-MFT, and then to
your PC.
4. Click Start > All Programs > Edwards Software >
SIGA-MFT Software to start the program.
During operation, the program may display a message
indicating that the external power supply is required. You can
plug in the external supply at any time during installation or
operation.
Refer to the SIGA-MFT Map Fault Tool User Guide
(P/N 3102035-EN) for instructions on using the tool to
troubleshoot the Signature SLC. A copy of the guide is
installed in the Edwards Software folder during installation of
the SIGA-MFT Software.
