2.7.8 Multiple Wireless Sensor Network Installation Restrictions
Firelite’s Wireless Sensor Network technology shares the RF spectrum with other Honeywell Wire-
less Sensor Network systems. Honeywell has established a limit of 4 overlapping networks to
avoid congestion in the RF spectrum. If the limit of overlapping systems is exceeded, a system
trouble will be generated for the system that detects 4 or more adjacent networks. To resolve this
situation, the instances of overlap need to be removed. Refer to Appendix C:, "Troubleshooting
and Testing"for suggestions on removing overlap between wireless networks. The trouble will be
self restoring up to 36 hours after the condition is resolved. To expedite the trouble resolution, tog-
gle the network that is reporting the trouble in and out of mesh formation mode.

2.7.9 Avoiding RF Interference
The Firelite 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 fromthe
Firelite wireless devices or that they operate on a different frequency band to ensure rapid mesh
formation. A properly installed Firelite 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 primary 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 Firelite 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 chan-
nel set. The system will log detection and avoidance of this kind interference in the W-GATE his-
tory as "Walkie Talkie Mode" Entry or Exit and in the NFS2-3030 history as Alternate Channel Set
or Normal Channel Set.
