LED
LED activity
Indicates...
Flashes for 10 seconds every 2.5 minutes. WCI is not a member of a network.
The WCI will join a network when the NWK LED is flashing. If there
is an open network nearby with the same rotary settings and the
WCI joins the network, the NWK LED turns on solid and then the
OPEN LED turns on solid.
Double Flash Pattern Router WCI searching for coordinator after losing communication
with coordinator.
Coordinator LED (yellow)
CRD
On solid WCI is network coordinator.
Open Net LED (yellow)
OPEN NET
On solid
Network is open for joining.
Off
Network is closed for joining.

Hardware failure or failed re-flash of a radio.
Corrective action: Replace the WCI
Triple flash pattern.
Failed to join network. Occurs for 30 seconds after failing to join a
network. Will continue this pattern until successful join.
Corrective action: Insure network is formed and open, then allow
time for WCI to join on its own.
Double flash pattern
• Normal for a repeater.
• WCI lost IMC communication to the UC/BCI/Tracer SC/SC+.
Corrective action: Check IMC wiring, then cycle power
to the controller/WCI to establish communication.
• WCI was not configured correctly. (WCI did not get BACnet ID
from UC/BCI/SC/SC+, and/or WCI did not get rotary address
from the UC/BCI/SC/ SC+.)
Corrective action: Cycle power to the controller/WCI
Power LED (green)
PWR
On solid
WCI has power.
Off
WCI does not have power.
Corrective action: Check WCI power wiring for 24v DC or AC.
(a)
LED will flash steady (about 3 flashes per second) on WCI that was built prior to 2019.
(b)
LED will appear to be on steady for WCI built 2019 and after. Will appear dim and flicker occasionally according to how much data is passing.
(c)
LED is off for all WCI.
(d)
LED will flash steady (about 3 flashes per second) on WCI that was built prior to 2019.
(e)
LED will appear to be on steady for WCI built 2019 and after. Will appear dim and flicker occasionally according to how much data is passing.
(f)
LED is off for all WCI.
(g)
If more than one condition is present, the priority is in the order listed.
Three Ways to Establish an Air-Fi® Network
An Air-Fi network can be established in the following situations:
• After a Tracer SC+ has been installed.
• Prior to Tracer SC+ installation.
• On a network that will not have a Tracer SC+ installed on it. This scenario includes applications that
combine Air-Fi Wireless sensors with hardwired BACnet network communication, both BACnet MS/
TP and BACnet/IP.
