Class A fault condition

missing the redundant class A connection.
missing the redundant class A connection.
If a suitable parent is available, the background mesh restructuring
routine should self-heal the network. If the network does not self-heal
after ten minutes, reduce spacing between devices or utilize SWIFT
Tools for suggested repeater placement to add stronger parents.
Activate mesh formation to trigger a mesh restructuring routine to re-
evaluate the trouble condition after taking action.

Jamming
Jamming occurs when a device is overloaded
with an interfering RF signal and is unable to
process incoming messages, but is able to report
the condition to its parents.
with an interfering RF signal and is unable to
process incoming messages, but is able to report
the condition to its parents.
A jammed device will automatically remove itself from the mesh
network after reporting the jamming. The device will attempt to self-
heal and recover into the network. Identify any possible sources of the
jamming signal and see if the spacing from the device to the jamming
source can be increased to an acceptable range. A site survey RF
scan test can be used to categorize the jamming signal.

Low battery
One or more of the four batteries are

of one week of operation remaining.
missing/dead and/or the device has a minimum
of one week of operation remaining.
To clear the low battery event, tamper the device and replace all four
batteries. When a device is tampered, it drops out of the mesh
network and attempts to rejoin as soon as the batteries are replaced
and the tamper event is cleared. Once a low battery trouble is
indicated there is a minimum of one week of operation before the
device is non-functional.

Duplicate address/
Illegal address
Illegal address
Two or more wireless devices on the same mesh
network that are set to the same address report a
duplicate address trouble. An address set to zero
will report an illegal address.

Verify the device has a profile. Verify that the profile matches the
profile in the gateway. Two different profiles may use the same mesh
ID. Remove and re-profile the device to guarantee the correct profile.
Verify the device is powered and the tamper condition is cleared.
Check the device spacing and the range from the device to the mesh.
A site survey link test can be used to verify connectivity from one

Use SWIFT Tools or panel history to investigate for the presence of
interference such as Walkie talkie/ RFID reader or unstable devices
(dropping and joining). Interference such as Walkie talkie/ RFID
reader will prohibit restructuring from fully executing. Devices joining a
mesh will delay the restructuring event.

A device drop event is indicated in history.
Device drop is the predecessor to a No Answer/Invalid reply trouble.
Inspect the area for any changes to the environment that could block
radio communication. Use a site survey RF Scan to check for any
interference and use a site survey link test to check the connectivity
from the device to its closest neighbor.

Use the network statistics provided by SWIFT Tools to identify the
interfering networks and the nature of the fault. The networks will be
listed by a unique number; this is not the serial number of the
gateway. One or more of the systems will need to be powered down to
clear the fault. Where possible, maximize the number of devices on a
mesh network to reduce the number of total mesh networks; i.e. use
one mesh network with 50 devices instead of two mesh networks with
25 each. Restructure the layout of the mesh networks to group
devices and the gateway to avoid overlap. It may take 36 hours for the
fault to clear. This can be expedited by toggling the state of mesh
formation.
