NOTE:
The panel supervision trouble/restore are internally generated events by the communicator.
Trouble is generated if the communicator misses 6 polls. Trouble is restored on receipt of first poll
from the panel.
SIM Lock Trouble (4 Flashes)
This trouble occurs when the SIM lock feature has been enabled and the unit has been programmed
with the wrong PIN for the SIM card.
Cellular Trouble (5 Flashes)
This trouble is indicated for any of the following 4 conditions:
1.
Radio Failure:
Trouble is indicated after 8 failed attempts to communicate with the cellular radio.
2.
SIM Failure:
Trouble is indicated after 10 failed attempts to communicate with the SIM.
3.
Cellular Network Trouble:
Trouble is indicated for loss of the registration to the network provider.
4.
Insufficient Signal Strength:
Trouble is indicated if calculated average signal strength is too low.
(Both green LEDs are OFF). Trouble will clear when the calculated average signal strength is
above minimum (i.e., > CSQ 5).
NOTE:
If Option [851][005] Bit 8 is Off, CSQ less than or equal to 4 will not trigger Cellular Trouble
Ethernet Trouble (6 Flashes)
This trouble is indicated when an Ethernet link between the transmitter and the local switch or router is
absent. This trouble will also be indicated if the unit fails to get Dynamic Host Control Protocol (DHCP) set-
tings from the DHCP server. (Not active if Ethernet receivers are not programmed).
Receiver Not Available (7 Flashes)
This trouble is indicated if the unit is not able to successfully initialize with any of the programmed receiv-
ers. Unprogrammed receivers are excluded. This trouble is also indicated if the cellular receiver APNs
have not been programmed in sections [205] and [215].
Receiver Supervision Trouble (8 Flashes)
This trouble is indicated when receiver supervision is enabled and communication between the com-
municator module and the receiver fails. Trouble is indicated if Ethernet 1 and/or cellular 1 is supervised
and does not receive a heartbeat from the receiver or if cellular is supervised and the unit does not
receive an acknowledgment to 4 heartbeats sent to the receiver.
FTC Trouble (9 Flashes)
This trouble is indicated when the unit fails to communicate module events to the central station. Trouble
is displayed after the unit has exhausted all communications attempts to all programmed receivers for
events generated by the communicator.
Module Configuration Trouble (12 Flashes)
This trouble is indicated when the system account code or the receiver account have not been pro-
grammed. Disabled receivers are excluded.
Red Network Connection Status LED
TL280(R)E / TL280LE(R) / TL2803G(R)E only
BLINKING
: Indicates communications in progress.
l
Once quickly for outgoing Ethernet transmission.
l
Twice quickly to indicate incoming Ethernet ACK/NACK.
OFF
: This is the normal state of the red network connection status LED. There are no network con-
nection issues present.
ON
: There is a problem with the Ethernet or the cellular network connection. LED will be ON if any of the
following occur: Ethernet cable is not connected, DHCP configuration times out, unit fails to get an IP
address from the cellular network, or Cellular connection has been reset.
(Green LED 1)
(Green LED 2) and
(Yellow LED) Signal Strength
NOTE:
If the yellow LED is flashing, signal strength in table below is not valid.
