Features
This section summarizes the key features of the Telguard TG-7 series.
Operating Mode
The Telguard is a digital cellular Data/SMS transmission device that is installed at the protected premises to
provide alarm transmission for security systems. The Telguard TG-7 series transmits alarm signals over the
nationwide digital cellular network if the telephone line or data network has been disrupted, compromised or
when there is no wire line service available.
Multiple Alarm Format Support
The Telguard TG-7 series supports multiple alarm communication formats.
Note: The Telguard unit's default program setting is for auto detection of the panel alarm format.
Auto Format Detect feature allows the Telguard unit to adapt to receive any listed format. If the alarm panel's
format is changed for any reason, the Telguard device will adjust to accept the new format.
In order for the alarm panel to be compatible with the Telguard, the alarm panel must be programmed to transmit
alarm messages to the central station using one of the following non-extended formats:
• Pulse Formats:
o 3+1 pulse; 10pps, Double Round, 1400 Hz ack
o 3+1 pulse; 20pps, Double Round, 2300 Hz ack
o 3+1 pulse; 40pps, Double Round, 2300 Hz ack
o 4+2 pulse; 20pps, Double Round, 1400 Hz ack
o 4+2 pulse; 20pps, Double Round, 2300 Hz ack
o 4+2 pulse; 40pps, Double Round, 2300 Hz ack
• Contact ID
• Modem IIe/IIIa
• SIA2 (SIA-DC-03 level 2 release at 300 baud)
• Sonitrol
• DMP
Hexadecimal account numbers can be used with 3+1 or 4+2 formats, as well as Contact ID and Modem (4 or 10
digits for Contact ID, 4 digits for Modem).
Complete Supervision of Communication Path
The Telguard TG-7 series of devices continuously supervises both the Telco and cellular communication
paths. If either communication path becomes inoperative, the Telguard device generates a relay trip output
that can be connected to a zone input of the host alarm panel and/or used to control remote annunciation
devices.
Line Fault Condition (LFC)
The Telguard unit monitors voltage on the incoming Telco line. If an inoperative Telco line is identified,
(voltage below –20vdc, on hook) a Telco line fault condition (LFC) is declared. The System Trouble Condition
LED (STC LED) will flash 3 times and the STC relay will trip after a programmable period of time. Upon Telco
restoral, the relay and STC LED are returned to normal.
