General Description and Operation
The Telguard TG-7 Dual Path Series communicator is an alarm transmission device that facilitates
the use of the cellular network or an internet-connected LAN (Ethernet) for the delivery of signals
for commercial alarm panels, providing the following three modes of operation:
•
Dual Path Cellular primary, LAN backup
•
Dual Path LAN primary, Cellular backup
•
Cellular Only (used for Sole Path)
In Dual Path mode, the communicator can use either the cellular or LAN path to transmit an event
from the panel and fail over to the other path when the primary becomes unavailable. In Cellular
Only mode, the communicator will not monitor for a LAN connection and strictly use cellular as the
means of communication. This mode also offers the ability to supervise the connection to meet
specific burg and fire requirements. The communicator can also be used as either a Primary or
Secondary Path device when an alternate communications path is connected to another Panel-Telco
interface or DACT. In such cases, panel settings determine the alarm reporting path.
When transmitting an alarm signal, the Telguard communicator obtains its data from the alarm
panel by way of a telephone interface, sometimes referred to as dialer-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) over the chosen path: cellular radio or
connected LAN. The TCC performs a function similar to a central station receiver and issues the
transmission acknowledgement 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 Acknowledgement feature shall
be enabled. This feature will cause a Radio Failure Condition when an acknowledgement cannot be
relayed from the central station to the communicator. This feature is optional for the United States.
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 Telguard dealer portal:
. 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.
In a typical alarm installation, the communicator is installed in the same area as the host alarm
system and is connected directly to the host alarm panel via the
jack
(black RJ-45). The communicator connects to the Telguard Communication Center (TCC) via a
built-in cellular radio or, when used as a dual path device, via an Ethernet cable that connects the
Ethernet jack (silver RJ-45) with an Internet-enabled premises LAN. Two programmable System
terminals in order to provide Telguard trouble signals to the alarm panel. Additionally, automatic
self-test and Check Status signals are transmitted exclusively to the TCC. The communicator
supports several 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 12VDC or 24VDC regulated power supplied by the connected alarm panel. The TG-PEM
Accessory is also available for adding multiple dry contact zones to TG-7 Dual Path Series
communicators in either fire or burglary systems (but not combinations systems), in cases where a
DACT connection is not available or more inputs are required.
