General Description and Operation
The Telguard TG-7 Cellular Series communicator is an alarm transmission device that facilitates the
use of the cellular network for the delivery of signals for commercial alarm panels, providing the
following three modes of operation:
•
Sole path
(Cellular Transmission Only)
•
Primary path
(Cellular Primary & Telco Backup
)
•
Back-up path
(Telco Primary & Cellular Backup
)
Depending on the TG-7 Cellular Series model and configuration (as set in the dealer portal), the alarm
panel will utilize the cellular network as a sole, primary or back-up (secondary) transmission path to
deliver alarm messages. In primary/backup mode, the communicator can use either the cellular or
Telco path to transmit an event from the panel and will fail over to the other path should the primary
become unavailable. In Cellular Only mode (Sole Path), the communicator will not monitor for a Telco
connection and strictly use cellular as the means of communication. The sole path mode also offers
the ability to supervise the connection to meet specific burg and fire requirements. In each case, the
communicator is connected to a panel Telco interface (DACT) with a cable that connects to the
-45 jack. The communicator can also be used as either a Primary or
Secondary Path device when an alternate communications path is connected to another Panel DACT.
In such cases, panel settings determine the alarm reporting path.
When transmitting an alarm signal via cellular, the Telguard communicator obtains its data from the
alarm panel by way of the DACT interface, a process sometimes referred to as dial-capture. The
communicator will obtain all alarm signal information including monitoring station phone number,
account number and all zones for every alarm transmission. The communicator handshakes with the
alarm panel and causes it to transmit the alarm data. The communicator encodes the alarm data and
securely transmits it to the Telguard Communication Center (TCC). The TCC performs a function
similar to a central station receiver and issues the transmission acknowledgment when the last
message in the transmission is received. After decoding and reformatting, the alarm signal is routed
to the desired alarm company monitoring station for action. For installations in Canada, a required
End-to-End Acknowledgment feature shall be enabled. This feature will cause a Radio Failure
Condition when an acknowledgment cannot be relayed from the central station to the communicator.
This feature is optional for the United States.
Two programmable System Trouble Condition (STC) relays provide supervisory trip outputs for
communicator trouble
signal to the alarm panel. Additionally, automatic self-test and Check Status signals are transmitted
exclusively over the cellular network with all Telco line and cellular monitoring, switching and
supervisory functions built in. The communicator
supports two power supply options: the
communicator can be plugged into a standard AC outlet (120 volts/60Hz) and will keep a dealer-
supplied battery charged, or the communicator can operate on either 12VDC or 24VDC regulated
power supplied by the connected alarm panel.
Telguard offers the ability to establish an override of the central station telephone and account
numbers stored in the panel by providing alternate central station values in the dealer portal
(telguard.com). This can be useful in situations where the installer codes are not known or the panel
cannot otherwise be reprogrammed. When the communicator is configured with override values, all
signals, whether alarm, trouble, or supervisory, will be sent to the override central station. To be able
to send different types of signals to different locations, the central station data for each type of signal
will need to be programmed into the panel and the override values left blank in the dealer portal. This
will cause the communicator to use the central station values as transmitted by the panel.
