1 General 1.1 Purpose When preparing a specification or quotation for the use of a Telguard cellular device in a commercial fire application, it may be necessary to supply a detailed functional description of the equipment. The architectural and Engineering Specifications presented in this publication cover such information for the TG-7FS LTE models— indiscriminate of variance—and are intended to be used for this purpose as required. 1.
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.

3 Functional Description 3.1 Signal Transmission from FACP to Central Station The path of a signal from the FACP to the Central Station receiver through the TG7FS LTE unit has three main stages: 1. Local capture of the signal: Using dialer capture technology 2. Data delivery to the TCC: By means of the carrier of choice 3. Delivery of the signal to the Central Station: Through a choice of IP or PSTN connection 3.1.
3.1.2 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.
(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. firealarmresources.

• • • Enclosure key lock. Terminal blocks: Pluggable screw terminal blocks, 3.5mm pitch. Set of 6-, 3-, and 2-position blocks. Transformer: UL Listed 12VAC 800mA. 4.3.2 Optional Accessories • • • • • • ACD-35 antenna cable: RG-8 UL approved cable in PVC jacket with 50-ohm TNC male connector and TNC female bulkhead. 35ft in length. ACD-50 antenna cable: RG-8 UL approved cable in PVC jacket with 50-ohm TNC male connector and TNC female bulkhead. 50ft in length.
5 Sole Path Installation 5.1 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.
Approved accessories as previously listed can be used to relocate or change the type of antenna used. 5.3 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.
