The table above displays firmware update indicator codes and meaning of each code. The updates can be made from com-

[984] Communicator Status
The communicator status sections provide the installer with the status of the communicator's functionality, operational read-
iness, and failures.
The communicator status is displayed as a 6- digit hexadecimal code. The code ranges between 00000F and 2220CF,
though not all numbers in this range are assigned. Each of the 6 digits represents a status or trouble indicator as below:
1.
Digits 1 and 2: Signal strength indicators display the presence/strength of cellular radio.
2.
Digit 3: Network Indicator, indicates the operational status of the network.
3.
Digits 4 and 5: Trouble Indicator displays the type of issue on the communicator or modules associated with and con-
nected to the communicator. See Table 8 on page 17 for a listing of possible values.
4.
Digit 6: Reserved, displays as 'F' or '-'.
For example, a value of 11002F means:
11- Signal strength is excellent
0 - No network issues
02 - Panel supervision trouble with the communicator
The status code for the radio signal strength, its typical troubles, possible causes and troubleshooting instructions is dis-
played in the following table.
