GSM/GPRS Alarm Communicators
The Device status indicator may be ON or OFF .The Device status indicator light is normally GREEN: when it is RED, this
indicates that there is no communication between the software and the Device; if it is ORANGE it means that there is a
communication in course. For GPRS Main Receiver and GPRS Backup Receiver this indicator is ORANGE when the
Receiver is initialized but NOT currently connected OR connected but NOT yet initialized.
P T M
This page refers to the “PTM (Panel Transmission Monitoring) function”, which allows the device to transmit calls over
the GSM network in the event of failed communication between the control unit and the receiver on the PSTN telephone line.
The Communicator restores to normal mode after 5 minutes on the GSM channel.
The PTM function considers communication to have failed when:
– It does not detect number dialling, if the “Check Dialling” option has been enabled (this option checks that telephone
numbers have been dialled correctly).
– It does not detect a kiss-off (the signal transmitted by the receiver when successful event communication has ended).
The kiss-off signal frequency is 1400 Hz.
All numbers are checked if the “Telephone Numbers” list is empty; otherwise only the numbers on the list will be checked.
Calls are transmitted over the GSM network when the programmed “Maximum Failure Number” has been reached.
Telephone Number: Enter the telephone numbers (up to a maximum of 4) to be called using the PTM function. These fields
are empty by default. If this fields are blank, the “PTM function” will check all the telephone numbers dialed by the control panel.
Check Dialling: Disabled at factory default, if enabled, the missed dialing (i. e. when the PTM does not detect the
number dialed by the control panel on the PSTN line) will be count as failure by the “PTM function”.
Max Failures: In this box, enter the total number of errors detected by the Communicator above which the PTM function is
activated. The PTM function is disabled by default (the default setting is 0); set a value from 1 to 4 to enable the PTM function.
I/O (GS3125 series only)
This page is used to program input or output modes, output activation events, polarity (N.C. or N.O.), reserved outputs and
remote activation SMS strings for reserved outputs.
Type: This column can be used to program terminals T1, T2 and T3 for the following modes:
– Input: Select this mode to enable the corresponding terminal as the input line. If this mode is selected, the Service
column is activated (see below).
– Output: Select this mode to enable the corresponding terminal as an open collector output.
These settings also automatically update the parameters on the “SMS dialer”, “Voice dialer” and “Phonebook” pages.
Polarity: This box is used to program the output/input standby status:
– Normally Closed with the output/input in standby, the corresponding terminal is negative.
– Normally Open with the output/input in standby, the corresponding terminal is floating.
Click the box corresponding to the ‘Polarity’ column to invert the parameter currently displayed.
Activation events: Click the column corresponding to the event to be programmed, in line with the relevant output. The tick
indicates that when this event occurs, the relevant output will be activated. Click the boxes to enter/remove the tick
.
Programming the events linked to an output causes some of the boxes corresponding to that output to be disabled.
Before you can begin programming, you will need to remove the ticks
from various boxes.
– PSTN Fault: If selected, the output will be activated in the event that the telephone line is not detected.
– GSM Fault: If selected, the output will be activated if the GSM network is not detected.
– HB Fail: If selected, the output will be activated in the event that the supervision message is not detected.
– FTC Signal: if selected, the output will be activated if communication with the receiver is not successful.
If the FTC Signal event is selected, the Monostable and Monostable Time may also be selected.
Reserved Output: When this option is selected, all other events selected to activate the corresponding output are
ignored. Click the box corresponding to the output to be activated through caller recognition or via an SMS command. To
activate the output using caller identification, program the telephone number on the “Phonebook” screen and enable the
option “Activates output” (see page Phonebook->Activates output).
Service: A tick
in this column indicates that the Communicator is in its SERVICE status, i.e. when lines 1 and 2
become unbalanced, instead of making a call, the Communicator will take a specific action independently. An action may
be specified for each line, in accordance with the table below. In any case, if these actions are selected, SMS messages
are never sent in reference to inputs 1 and 2.
