Communicator Status Leds - DSC neo TL280E Installation Manual

Cellular alarm communicator, internet and hspa dual-path alarm communicator, internet alarm communicator

Table of Contents

NOTE: When Panel displays "Alternate Communicator Fault", communicator programming is not accessible via the keypad.

The communicator has four on-board LED indicators. These include one yellow trouble LED, one red network connection

status LED and two green signal strength LEDs. The LED meaning is described in this section.

Yellow Trouble LED

This yellow LED will flash to indicate a trouble on the unit. The number of flashes indicates the type of trouble. See the table

below for the coded flashes and the conditions which will activate the trouble status LED.

Flashes

NOTE: Only the highest priority trouble (2 flashes is the highest priority trouble) is indicated. When this trouble is restored, the

next highest trouble will indicate, if present. This will continue until all troubles have been cleared (yellow LED is not

flashing).

The following paragraphs describe the conditions associated with the trouble indicated:

Panel Supervision Trouble (2 Flashes)

This trouble will be indicated 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 com-

municator 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.

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) settings from the DHCP server. (Not active if Eth-

ernet 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 receivers. 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 communicator 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.
