Establishing the Network
On power-up, the WCI goes through a check list and updates LED activity according to the type of
device associated with the WCI and the status of the WCI in the network. The LED flash patterns
vary depending on current conditions. LED behavior is described in
Table 2.
LED identification and interpretation
LED
LED activity
Indicates...
Network LED (green)
NWK
On solid
WCI is a network member.
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.
Sensor LED (green)
SNSR
Flashes slowly
Sensor has lost its association with the WCI.
Flashes quickly
Sensor is associated with the WCI and the
sensor button has been pushed.
On solid
A sensor is associated with the WCI.
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.
Reception LED (yellow)
RX LINK
Flickers
Data is being received.
Transmission LED (green)
TX LINK
Flickers
Data is being transmitted.
Diagnostic LED (red)
DIAG
Flashes 50% on/off
Hardware failure or failed re-flash of a radio.
Corrective action: Try updating the firmware.
Triple flash pattern. Occurs for 30
seconds after failing to join a
network.
WCI is not configured correctly, or the unit
controller, IMC communication, or a repeater is
down.
Corrective action: Cycle power.
Double flash pattern
One of the following causes:
• WCI lost MAC address on radios or WCI lost
ability to communicate with radio.
• WCI could be a repeater.
• WCI lost IMC link to the UC/BCI/PM014
Corrective Action: Cycle power to restore
communications with unit controller. MAC
address can be checked on TU >Wireless >
Advanced page when connected directly to the
controller (if UC to WCI comm is up).
If more than one condition is present, the priority is in the order listed.
Power LED (green)
PWR
On solid
WCI has power.
