Panel Supervision Trouble (2 Flashes); Cellular Trouble (5 Flashes); Ethernet Trouble (6 Flashes); Receiver Not Available (7 Flashes) - DSC TL280LE-LAT Instruction Manual

Panel Supervision Trouble (2 Flashes)

This trouble occurs when communication between the communicator module and the panel fails. If the module can not com-
municate with the panel (e.g., loss of power to the panel) the communicator will send the 'Panel Absent Trouble' event mes-
sage to the central station receiver. When communication returns, a 'Panel Absent Restore' event is sent by the
communicator to the central station receiver. The reporting codes are ET0001 for trouble and ER0001 for restore. The
Panel Absent event always uses the primary receiver account code when communicating to the central station.
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.

Cellular Trouble (5 Flashes)

This trouble occurs 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 occurs 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) settings from the DHCP server (not active if
Ethernet receivers are not programmed.

Receiver Not Available (7 Flashes)

This trouble occurs if the unit is not able to successfully initialize with any of the programmed receivers. 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 occurs if the receiver supervision is enabled and communication between the communicator and the receiver
fails. The trouble is indicated if any supervised communications path does not receive an acknowledgement to a heartbeat
signal from 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 completed all communications attempts to all programmed receivers for events generated by the com-
municator.

Module Configuration Trouble (12 Flashes)

This trouble is indicated when the system account code or the receiver account have not been programmed. Disabled
receivers are excluded.

Red Network Connection Status LED

TL2803G(R)E / TL280LE(R)
BLINKING: Indicates communication in progress.
Once quickly for outgoing Ethernet transmission.
l
Twice quickly to indicate incoming Ethernet ACK/NACK.
l
OFF: This is the normal state of the red network connection status LED. There are no network connection 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)
NOTE: If the yellow LED is flashing, signal strength in table below is not valid.
See Table 8 for troubleshooting flashing yellow LED.
