Table 2 - BGSM-120 Communicator status indications provided by the flashing of the green LEDs (L1, L2, L3)

This Communicator offers the option of selecting the "Primary Path" for communication purposes. Will provide the line ring voltage for incoming

calls and will decode DTMF dialling. The Simulated land line provides the alarm control panel or an alternative communication terminal, with

a backup line in the event of PSTN line trouble. Commutation between PSTN and GSM, does NOT occur during ongoing calls. The

Operating priority (selected during programming) determines how this Communicator manages communication (SMS and voice for the

BGSM-120 only series), as well as calls from telephone devices connected to the LI terminals (such as a burglar alarm control panel).

, , , , , This Communicator is unable to decode Pulse dialling.

, , , , , To prevent any unwanted use of a simulated line via GSM, the equipment gives out a signal in the form of a double beep

during vocal calls. The first double beep is produced after 5 minutes and the following ones at 30 second intervals each.

Restore default programming

To restore the default programming of the transmitter, proceed as follows:

1. Disconnect the transmitter from the power supply.

2. Keep terminals 1 and 4 on connector [9] (fig. 5, page 40) short-circuited, using clamps for example, and restore the power supply.

3. The 5 LEDs (L1, L2, L3, L4 and L5) will light up briefly (less than 1 second).

4. As soon as the short circuit is detected, the 3 green LEDs (L1, L2, L3) switch off, while the yellow and red LEDs (L4, L5)

remain illuminated (for a few seconds) to indicate that default programming is being restored.

5. When the yellow and red LEDs (L4, L5) light up, remove the short circuit between terminals 1 and 4 on connector [9] (fig. 5, page 40).

6. Once this procedure is complete, the 3 green LEDs flash to indicate that the transmitter is initialising.

PSTN pre-set channel

If the voltage on the land line terminals (LE) drops below 3V dc for a period of between 10 to 3600 seconds ( programmable

value ), this Device will switch the connected telephone device (connected to the LI terminals) to the GSM Network. When

the PSTN telephone line is restored, it commutates once again, after a programmed period of time, to the PSTN telephone line.

GSM pre-set channel

This provides the devices connected to the LI terminals with a simulated line if GSM reception is detected. If there is no GSM

reception, it commutates to the PSTN telephone line.

Contact ID transmission sequence on GPRS

The Communicator, if telephone numbers have been entered on the page GPRS->Telephone numbers to decode for

decoding using the BGSM-120 Console software, directs calls to these numbers over the GPRS line.

When an event is triggered, the Alarm Panel goes off-hook.

The dial tone is simulated.

Control Panel dials the number of the central station. Ensure the alarm panel inserts a minimum 1-second pause, or has

dial tone search enabled before dialing the number.

The Communicator will send the required Contact ID dual tone handshake.

After receiving the handshake, panel transmits alarm message in DTMF format.

The Communicator decodes and transforms DTMF digits into the packet and sends it to the Central Station Receiver over

the GPRS network.

The receiver acknowledges the event and sends command to the Communicator to generate the corresponding kiss-off

signal to the control panel.

After the Communicator generates kiss-off, the panel goes on-hook if no more alarms need to be sent, or it can send the next alarm.
