2.9.10  Trouble MessagesDistributed Firmware Updates
Starting with version 3.0 and higher, firmware updates for devices in the mesh network can be distributed via the mesh network from the 
gateway. SWIFT Tools is required to initiate the firmware upgrade procedure. Refer to Appendix E for firmware upgrade instructions.
An entire mesh network of devices can be upgraded assuming certain preconditions are met:
all devices are running application code version 3.0 or higher,
there are no active “low battery” troubles,
there are no active “class A” connectivity fault conditions,
the mesh is in “normal mode”.
Failure to meet the preconditions will be indicated via SWIFT Tools, and must be remedied before the mesh upgrade can continue.
All wireless points associated with the mesh network will be indicating a “no answer” trouble or “invalid reply”. There are two phases to 
the mesh upgrade procedure. 
Phase 1 - Mesh upgrade preparation:
Trouble Message
Type
Description
Course of Action
RF JAMMING or 
JAMMING
Non-latching
The gateway is being overloaded 
with RF energy and is unable to 
receive messages from other 
devices. 
Identify any RF emitters in close proximity of the 
gateway and remove them or relocate the gateway.
SOFTWARE MISMATCH 
or SOFTWARE
Non-latching
Software mismatch between the 
application code for the RF 
processor and the SLC processor.
Use SWIFT Tools to identify the mismatch, and 
update the processors as necessary for compatibility.
RF MESH FORMING or
RF MESH
Non-latching
The gateway and attached devices 
are searching for additional 
devices to join the mesh. The 
wireless system is not able to 
provide fire protection during this 
time.
Wait until all desired wireless devices are 
communicating and are members of the mesh 
network. Once all desired devices are in the mesh 
network, the mesh forming mode can be terminated 
by the user by activating the Mesh formation 
magnetic sensor or by using the SWIFT Tools. If no 
action is taken, this mode will automatically exit 10 
minutes after the last device joins.
RF MESH NOT FORMED 
or RF MESH
Non-latching
The gateway contains a profile but 
has not formed a mesh.
RF MESH REFORMING or 
RF MESH
Non-latching
The gateway is performing the 
initial identification and assignment 
of optimal communication paths for 
the mesh network.  The wireless 
system is not able to provide fire 
protection during this time.
No action needed. The duration of this event 
correlates to the number of devices in the mesh. A 
fully loaded mesh may take up to 5 minutes to 
restructure.
NO PROFILE
Non-latching
The gateway is in the factory 
default state and is not providing 
fire protection.
A profile needs to be created or assigned to the 
gateway before a mesh can be formed.
ADDRESS FAULT or 
ADDR FAULT
Non-latching
There is either a device in the 
mesh set to address 0 or there is a 
duplicate address used for another 
wireless module at the address of 
the gateway.
The offending device (detector or module set at 
address 0 or module at the same address as the 
gateway) will be indicating the LED pattern for 
address fault. Find and resolve that device.
RF OVERLAP
Non-latching
Wireless communication reliability 
is compromised due to the 
installation limits of Silent Knight 
wireless systems being exceeded.
Investigate for overlapping or adjacent wireless 
systems produced by Silent Knight. Reduce the 
instances of overlap by removing systems, or devices 
in the overlapping region. Refer to Section 2.9.7 on 
the installation limits for the Silent Knight wireless 
system. 
RF DEVICE NO ANSWER 
or DEV NO ANS
Latching trouble; remains 
active for the first 90 
seconds before it can be 
cleared with a system 
reset.
A wireless device that was part of 
the mesh has dropped from the 
mesh. The trouble is reported at 
the FACP 90 seconds after the 
device drops from the mesh.
Initiate a system reset at the FACP at least 3 minutes 
after the trouble was initiated to clear.
If the device was intentionally removed, no further 
action is needed.
If the device was not intentionally removed, refer to 
panel history or active panel troubles to investigate 
the cause of the disturbance.

CAUTION: NO FIRE PROTECTION
DURING THE UPDATE, THE MESH NETWORK WILL NOT PROVIDE FIRE PROTECTION.
