2 System Summary
2.1 Unit Description
The Telguard TG-7FS LTE is a line of digital cellular radio alarm transmission devices
used to provide the following three methods of communications for FACP units via a
cellular network:
• Sole path (Cellular Transmission Only)
• Primary path (Cellular Primary & Telco Backup)
• Back-up path (Telco Primary & Cellular Backup)
2.2 System Overview
Depending on the configuration (determined at time of installation), the FACP will
use the TG-7FS LTE as sole, primary or back-up (secondary) transmission path to
deliver alarm messages. When it is configured as a backup, it will provide
transparent access from the FACP to the central station. When transmitting an alarm
signal using the cellular path, the Telguard obtains its data from the alarm panel by
way of a Telco line interface. The Telguard will obtain all alarm signal information
including monitoring station phone number, account number and all zones for every
alarm transmission. The Telguard handshakes with the FACP causing it to transmit
the alarm data. The Telguard encodes the alarm data and transmits to the Telguard
Communication Center (TCC) over the digital cellular network. 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 appropriate alarm
company monitoring station for action.
In a cellular back up alarm installation, the incoming Telco line is connected from the
premises’ RJ-31x jack to the Telguard and then from the Telguard's RJ-45 jack to the
alarm panel in the normal fashion. Two programmable System Trouble Condition
(STC) relays provide supervisory trip outputs for connection to the FACP’s trip zone
input terminals in order to provide a Telguard trouble signal. Additionally, automatic
self-test and remote query signals are transmitted exclusively over the cellular
network with all Telco line and cellular monitoring, switching and supervisory
functions built in. No extra modules are required. The Telguard TG-7FS LTE has its
own power supply which keeps the Telguard battery charged.
