DSC LE2080 Installation Guide

Panel Supervision Trouble (2 Flashes)
This trouble occurs when communication between the communicator module and the panel fails.If the module can not
communicate with the panel (e.g., loss of power to the panel) the communicator will send the ‘Panel Absent Trouble'
event message 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 usesthe 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 gen-
erated if the communicator misses 6 polls. Trouble is restored on receipt of firstpoll from the panel.
Cellular Trouble (5 Flashes)
This trouble occurs for any of the following 4 conditions:
1.
RadioFailure: Trouble is indicated after 8 failed attemptsto communicate with the cellular radio.
2.
SIMFailure: Trouble is indicated after 10 failed attempts to communicate with the SIM.
3.
CellularNetwork 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: IfOption [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 act-
ive ifEthernet 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.
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 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 addressfrom the cellular net-
work, or Cellular connection has been reset.
(Green LED 1) (Green LED 2) and (Yellow LED) Signal Strength
NOTE: Ifthe yellow LED is flashing, signal strength in table below is not valid.
