Features
This section summarizes the key features of Telguard TG-7 Dual Path Series communicators.
Operating Mode
The TG-7 Dual Path Series is comprised of transmission devices that are installed at protected
premises to provide signal transmission over cellular and Internet-enabled LAN connections for
alarm systems. The communicator transmits alarm signals over the nationwide digital cellular
network if the premises Internet connection has been disrupted or compromised, when there is no
LAN connection available, or when set for primary or sole path use of the cellular pathway. When
set in LAN primary mode, the communicator will first attempt to transmit alarm signals over the
LAN pathway.
Multiple Alarm Format Support
The Telguard TG-7 Dual Path Series communicator supports multiple alarm communication formats.
NOTE: The communicator
auto detection of the panel alarm format.
Auto Format Detect feature allows the communicator to adapt to receive any listed format. If the alarm
format is changed for any reason, the communicator will adjust to accept the new format.
See Appendix 1 for a list of compatible alarm formats and compliance requirements.
Complete Supervision of Communication Path
The communicator continuously supervises the connection to the alarm panel and the cellular and
LAN (when not set in cellular-only mode) pathways. If any of these pathways becomes inoperative,
the communicator can generate a relay trip output that can be connected to a zone input of the
host alarm panel. These System Trouble Conditions (STCs) are described below.
LAN Failure Condition (LANFC)
The communicator monitors the LAN connection by verifying that messages can be sent to the
Telguard Communications Center (TCC) and an acknowledgment returned. If an initiated message
cannot reach the TCC, a LAN Failure Condition (LANFC) is declared and the LEDs indicate the type
of trouble condition. The System Trouble Condition LED (STC LED 2) will flash 3 times, and the STC
relay will trip after a programmable period of time. LED 6 (LAN STC LED) will also flash in a specific
pattern to indicate the possible cause of the LANFC issue:
•
Single flash: LAN connection not detected.
Check the wiring connection between the
communicato
-45 and premises LAN port (typically a router or switch).
•
Two flashes: Unable to obtain IP Address from LAN.
Check with the System Administrator
for the premises. A static IP address may be needed.
•
Three flashes: Unable to reach Internet.
Check with the System Administrator for the
premises. The Gateway Address may be incorrect.
•
Four flashes: Expected TCC acknowledgement not received.
Call Telguard Technical
Support as additional troubleshooting will be required.
NOTE: When the communicator is configured to use a sole communications path (cellular), the
LAN Failure Condition (LANFC) is not applicable and LED 6 will remain off.
