Transmetteur d'alarme gsm/gprs

Les langues disponibles

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.

, , , , , 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.

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-100 Console software, directs calls to these numbers over the GPRS line.

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

The Communicator will assert dial tone.

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.

This Communicator has 3 outputs programmable as Automatic (outputs with this attribute will activate in response to the

associated events) ) or Remotely, through receiving a telephone call from a previously programmed number.
