2. Remove power from the SCW9055/SCW9057 and disconnect the backup battery
connections.
3. Gently slide the SIM card into the SIM card holder and ensure the notch in the corner of the
SIM card aligns with the indication on the PCB.
4. Apply AC power to panel, and replace the panel cover.
NOTE: If two way audio is enabled you CANNOT swap the SIM card with another card.
COMMUNICATOR RESET
The Communicator can be reset by cycling the power on the SCW9055/SCW9057.
ESTABLISHING A COMMUNICATION CHANNEL WITH THE SCW9055/
SCW9057 P
ANEL
The Communicator interfaces to the SCW9055/SCW9057 through a keyed 16-pin Ribbon
cable. See Table 6 . The key prevents incorrect connection of the ribbon cable connector to the
SCW9055/SCW9057 and Communicator. The pin-out for the Ribbon cable is provided in the
Table below:
Establishing a communication channel between the Communicator and the SCW9055/
SCW9057 is critical to ensuring the desired operation of the two units. The following steps
must be completed during the on-site installation. Program the following options to ensure that
the Communicator and the panel work together as intended.
Initial Programming of Communicator and SCW9055/SCW9057
1. Enter
[*][8][Installer Code] [Section Number]
for panel programming. Record any values
that are modified from their default, in the appropriate Programming Worksheets.
NOTE: When programming Toggle Options, the toggle is ON when the number is displayed
and OFF when the number is not displayed. (e.g., [1---5---], Toggle Options 1 and
5 are ON, all others are OFF).
2. Panel section [167] Cellular Interface Communications ‘Wait for ACK’: Default value is:
060 seconds.
3. When the communicator is installed with the SCW9055/SCW9057 panel, four telephone
numbers are available to backup one another. You can set up these four telephone numbers
to perform in one of two ways: Backup dialing or Alternate dialing.
a. Backup dialing: Each of the four telephone numbers make five dialing attempts in turn,
before an FTC trouble is displayed on the keypad.
b. Alternate dialing: each telephone number makes one dialing attempt before moving on
to the next number, cycling through each of the four numbers for a total of five times
each. If all four numbers fail the five attempts, an FTC trouble is displayed on the
keypad.
4. Panel sections [301], [302], [303], and [305] can be configured as Primary communication
paths.
