Digital Security Controls Ltd. 163G4005 Manual De Usuario

This provides the devices connected to the LI terminals with a simulated line if GSM reception is detected. If there is no GSM re-
ception, it commutates to the PSTN telephone line.

The Communicator, if telephone numbers have been entered on the page Phonebook using the software DLS 5 Console, 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.



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 the command to this Communicator, which generates the corresponding
kiss-off signal (at a frequency of 1400 Hz) and sends it 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.

In SMS dialer operating mode, one or more telephone numbers (the first 8 entries in the phonebook, max 16 digit programmed as
SMS Dialer) are sent SMS messages (as programmed previously) corresponding to the following events.


Alarms which may occur on one or more of the 6 programmable input lines. Remember that 2 SMS messages can be programmed
for each of the 6 input lines on the device, one for Activation and one for Restore.



PSTN line test. 2 SMS messages may be programmed: one for PSTN line absence and one for Restore.



Power supply voltage test. 2 SMS messages may be programmed: one indicating Power supply voltage problems and one for Restore.



Tamper Test. 2 SMS messages may be programmed: one indicating Tamper and one for Restore.



Periodic SMS message, with a programmable time period between 1 hour and 1 year.



During operation in Voice dialer mode, one or more telephone numbers (the first 8 entries in the phonebook, programmed as Voice
Dialer) are sent a prerecorded voice message. Up to150 messages may be recorded, each with a maximum duration of 6 seconds.
Each message is recorded onto a solid state memory (flash memory). The messages are linked to the following events.


Alarms which may occur on one or more of the 6 programmable input lines. Remember that 3 voice messages can be recorded for
each of the 6 input lines on the device.



PSTN line test. 3 voice messages may be recorded: 3 for PSTN line absence and 3 for Restore.



Power supply voltage test. 3 voice messages may be programmed: 3 indicating Power supply voltage problems and 3 for Restore.



Periodic voice message, with a programmable time period between 1 hour and 1 year.

A voice call takes place when an event occurs on a channel for which a voice message and at least one telephone number has
been programmed. In this case, the Communicator performs the following steps:
1. The Communicator selects a telephone number and forwards the call over the GSM telephone line.
2. The Communicator makes sure that the number is not busy and that there are no problems on the GSM network, so that it

can proceed with the next step, otherwise the call will end and step 1 will be attempted again, up to a maximum of 8 times
(depending on the programmed value). After 8 attempts the call cycle will be considered complete. If the alarm channel has
been programmed to call several telephone numbers, they will be called in a set sequence. By doing this, for example, the
possibility of calling a busy number several times in the space of a few seconds can be avoided.
