System Summary
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)
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.

Functional Description
Signal Transmission from FACP to Central Station
The path of a signal from the FACP to the Central Station receiver through the
TG-7FS LTE unit has three main stages:
- Local capture of the signal: Using dialer capture technology
- Data delivery to the TCC: By means of the carrier of choice
- Delivery of the signal to the Central Station: Through a choice of IP or PSTN connection
Dialer Capture
The TG-7FS LTE unit has a patented integrated interface that allows digital dialers to dial into the unit using the following specifications:
- Line voltage : -30 Vdc into standard telephone device when on hook.
- Dial tone : Precision 350 + 440Hz +/- 1%. 10 digits dial out capability.
- Mode: Loop start only. 25mA +/- 10% off-hook.
As long as the TG-7FS LTE unit has a proper connection to the wireless network, it will provide a dial tone for the FACP to use. Once the FACP has dialed in, the TG-7FS LTE will interact with the panel by providing handshakes and kiss-offs, similar to a Central Station receiver. Provided that the alarm data received is valid per the alarm format protocol, the TG-7FS LTE will capture the message and pertinent information for delivery, while the FACP will be satisfied with the received kiss-off. If an invalid format, or invalid data is captured, no kiss-off will be provided. Compatible formats for the TG- 7FS LTE units are
- Pulse Formats (Hexadecimal account numbers can be used):
- 3+1 pulse; 10pps, Double Round, 1400 Hz ack
- 3+1 pulse; 20pps, Double Round, 2300 Hz ack
- 3+1 pulse; 40pps, Double Round, 2300 Hz ack
- 4+2 pulse; 20pps, Double Round, 1400 Hz ack
- 4+2 pulse; 20pps, Double Round, 2300 Hz ack
- 4+2 pulse; 40pps, Double Round, 2300 Hz ack
- Contact ID (Hexadecimal account numbers can be used, 4 or 10 digits in length)
- Modem IIe/IIIa2/4 (Hexadecimal account numbers can be used, 4 digits in length)
- SIA2 (SIA-DC-03 level 2 release at 300 baud)
- Sonitrol
- DMP
Cellular Transmission
Once the signal is obtained by the TG-7FS LTE, it is encrypted (128-bit AES)
and packetized for digital delivery via the cellular network. Depending on the
version of the TG-7FS LTE unit used (Verizon or AT&T), the carrier of choice
will be used. All transmissions between the TG-7FS LTE and the TCC will occur
via the best available technology at the time, with data sessions being the
primary delivery path and SMS being the secondary option. The TG-7FS LTE can
work on different bands depending on the carrier of choice:
- AT &T supported bands: 3G B2/B5, LTE B2/B4/B5/B17
- Verizon supported bands : LTE B4/B13
Similar to the way a central station receiver operates, the TG-7FS LTE will not be satisfied until there is an acknowledgment of receipt from the TCC. If acknowledgment is not received by the TG-7FS LTE, a failure will be created and annunciated via suppression of the dial tone.
Delivery to Central Station
After the TCC receives the data, it will process for its delivery. Based on
the subscription options chosen during the registration of the TG-7FS LTE, the
TCC can either use the captured phone number and account number to deliver the
signal or use a predetermined phone number and account number to redirect the
signal. A third option that is available to companies that have set up a
connection with a Central Station ahead of time is to use IP delivery rather
than POTS to send signals to Central Station. The TCC can deliver signals via
IP using the Fibro protocol (for Contact ID and SIA formats) to Surgard
receivers, as well as using DMP protocol to send to DMP receivers. Whether
using POTS or IP for delivery, the TCC uses an acknowledgment-based retry
sequence, where it requires receiver acknowledgment
Link Supervision for Sole Path installations
NFPA 72 requirement
The TG-7FS LTE unit provides a feature known as “Link Supervision” that
complies with NFPA 72, editions 2010-2016 for use a sole path communicator.
Link Supervision is a feature by which the TCC checks the unit’s connectivity
and will create a signal to be delivered to the Central Station if a
disruption in service is discovered, lasting 5 minutes (per 2010 edition
requirements) or 60 minutes (per 2013 and 2016 edition requirements).
Link Supervision
Link Supervision must be enabled from the online portal. It will reprogram the
device to initiate check-in signals over the data network, at a frequency that
is much higher than the disruption timeout (5 or 60 minutes). If the TCC
detects that there has been no communication for the predetermined disruption
timeout, it will create a signal (customized during registration) that will be
delivered to the Central Station. Once the check-ins resume, a restoral signal
will be created and delivered as well. The check-in signals are between the
TG-7FS LTE and the TCC and are therefore not visible to the FACP or the
Central Station.

Sole Path Installation
Power Up Requirements
The TG-7FS LTE unit must comply with the NFPA 72 requirements which state that
the unit will have a secondary power source besides the main power source,
that will allow it to go remain uninterrupted for 24 hours at the end of which
period it should be able to handle 5 minutes of signal transmission on the
secondary power source. While for primary power source, the provided
transformer is expected to be used, the TG-7FS LTE units do not come with a
battery included. However, the following consumption rates are to be used to
calculate the size of the battery required.
12VDC : 40mA (idle with link supervision enabled), 160mA (transmitting)
Note : For a UL approved installation, the transformer and connections must be protected. A UL Listed pull box must be used in conjunction with a UL Listed outlet box and receptacle. Same guidelines that apply to the FACP power supply installation should apply here.
Signal Strength Requirements
It is recommended that the signal strength during the time of installation
follows our guidelines to reduce the amount of perceived network issues.
Having a lower signal strength than recommended may result in a higher number
of incidents as it is the nature of the cellular network to fluctuate in
quality and bandwidth

4| LED 5-2 = on| ³ -60
Approved accessories as previously listed can be used to relocate or change the type of antenna used.
Communication and Supervision Requirements
If using the TG-7FS LTE unit as the sole path of communication, it will be
necessary for the TG-7FS LTE unit to provide dial tone to both Telco
connections on the panel, unless one can be disabled. To do this, the Tip and
Ring connection on the FACP must be connected in parallel for both Telco
connections. As far as supervision of the TG-7FS, there are two System Trouble
Condition relays that can be used to locally annunciate to the panel of any
issues, as programmed during registration. However, the TG-7FS LTE will also
announce through the suppression of the dial tone to the panel of any issues
caused by No Service or Radio Failure conditions.
Note : Because a low/missing battery or low/missing AC power on the TG- 7FS LTE unit will not results in any other type of annunciation, at least one STC relay should be connected to a zone on the FACP.
