JFWSG FlashScan Wireless System Gateway
Initial Mesh Restructuring Mode
Initial mesh restructuring mode automatically runs after each mesh formation. The gateway and
peripheral devices do not provide fire protection during the initial mesh restructuring mode. Mesh
restructuring analyzes signal strengths between devices. The gateway designates the primary and
secondary communication paths between devices that provide a redundant path for all transmis-
sions. Mesh restructuring automatically terminates once all devices have a redundant communica-
tion path and signal strengths that meet the requirements of primary and secondary transmission
paths. Any device that does not have a redundant path or meet the requirements for signal strength
will report a fault.
The gateway reports a 'RESTRUCTURING' or 'RSTRCT' trouble to the FACP. The gateway
reports "Restructuring" to the communicator display of the SWIFT Tools application.
Normal Mode
Normal mode is the network's standard operating state. The mesh network has been formed and is
providing fire protection. The mesh network will continuously search for additional devices with a
matching profile to join the mesh. To avoid interference, the mesh network periodically checks for
adjacent mesh networks created by JCI. The gateway reports "Normal" to the communicator dis-
play of the SWIFT Tools application.
Rescue Mode
During normal mode, if an out-of-network device with a matching profile is discovered by the net-
work, the gateway will trigger rescue mode in all communicating devices. All devices in communi-
cation continue to provide fire protection during rescue mode but also search for a lost or added
device. Rescue mode automatically terminates 3 minutes after the last device is rescued and returns
to normal mode. The gateway does not report troubles during rescue mode but reports "Rescue" to
the communicator display of the SWIFT Tools application.
Mesh Restructuring Mode
In addition to the initial mesh restructuring mode, mesh restructuring is automatically performed
after any restoration of communication to a device or to recover from a link failure (Class A fault).
Mesh restructuring that occurs during normal mode does not generate a trouble message. During
mesh restructuring, fire protection is provided by all devices that are participating in the mesh com-
munication. The gateway reports "Restructuring" to the communicator display of the SWIFT Tools
application.
Bootloader Mode
The gateway enters the bootloader mode when its firmware is being updated using SWIFT Tools.
The gateway does not communicate with the FACP during bootloader mode. The gateway reports
"Bootloader" to the communicator display of the SWIFT Tools application.
2.9.2 LED Patterns
The LED indicator patterns are provided in Appendix D on page 59.
2.9.3 Lock/Unlock the Gateway
The gateway can be locked to prevent access to the magnetic sensors and to password-protect all
wireless interactions. The lock function can be performed by SWIFT Tools or by the FACP. When
SWIFT Tools is used to lock the gateway, a password must be provided for all future interactions,
including unlocking the gateway. When the gateway is locked by the FACP for the first time, a
default password of "12345" is applied. If the gateway was previously locked with a password from
SWIFT Tools, the previous password will be applied. Use this password for all future interactions
with the SWIFT Tools application.
