SWIFT® Smart Wireless Integrated Fire Technology Manual — P/N LS10036-000SK-E:B  11/9/2017

WSK-WGI Wireless System Gateway

The state of the trouble condition will be indicated by SWIFT Tools as well as the FACP. Mesh Statistics in the diagnostics screen of 

SWIFT Tools will provide further details regarding the condition of overlap and recommendations.

The trouble generation of a synchronization fault may be disabled for any installation that does not require mesh-to-mesh synchroniza-
tion. Mesh-to-mesh synchronization is not required for installations that utilize only wireless input types (detectors, monitor modules, 

pull stations) with no wireless output device types (relay, AV base, sync module). Mesh-to-mesh would not be required for installations 
that utilize only wireless output devices types with no wireless input device types. Mesh-to-mesh synchronization would not be required 
for installations where the mesh networks are not operating in a co-operative manner, i.e. the output devices of a particular mesh network 

will not be controlled by the events of another mesh network. This will be applicable for mesh networks that are in separate zones with 
no dependencies on each other.
To disable the mesh synchronization fault reporting use SWIFT Tools (add the instructions here, process yet to be determined. It will be 

similar to the weak link trouble reporting).

The SWIFT wireless mesh network uses radio frequency hopping spread spectrum technology to communicate in the 900 MHz ISM 
band (902MHz to 928MHz). Other commercial and industrial products also operate in this band. If two-way radios or other wireless 

communication devices are used during the installation process, it is recommended that they be kept at least 4 feet away from the Intelli-
Knight wireless devices or that they operate on a different frequency band to ensure rapid mesh formation.
A properly installed SWIFT wireless mesh network with primary link reporting enabled will be highly immune to RF interference from 

other wireless products even when they are nearby. The use of the weak link reporting feature is highly recommended. If the system is 
installed in a controlled environment where other 900 MHz ISM band devices will not be present, the primary link reporting feature may 
be disabled to permit greater distances between installed devices if required.
The SWIFT wireless mesh network will be able to automatically detect and avoid certain types of in-band channel interference (often 
caused by two-way radios) by using an alternate channel set. The system will log detection and avoidance of this kind of interference in 
the gateway history as “Walkie Talkie Mode” Entry or Exit.
