The 2010 edition of NFPA 72 allows a single, UL 864 listed TG-7FS to replace all of your customers existing fire panel landlines. The TG-7FS can serve as the sole communications path for commercial fire alarm systems, transmitting alarm signals from the fire panel over the digital cellular network to the designated monitoring station.

On average, cellular monitoring costs the end user significantly less than a dedicated landline. Furthermore, each month they will pay you instead of the local telephone company for the communications path. For each landline they replace with a TG-7FS, their monthly communications bill decreases while your RMR increases.

True Drop-In Replacement

The TG-7FS is dial capture based so all you need to do is unplug the landline and plug in the new cellular communicator. All other aspects of the system—from the master control unit through the central station—won't notice the difference.

Every Panel, Every Time

Because the TG-7FS uses dial capture to interface with your customers’ existing panels and supports virtually all alarm formats, it works with every panel, every time.

Five Minute Supervision

For existing installations, all landlines can be swapped for a single TG-7FS because of the new five-minute supervision mode. When installed with multiple communications technologies, it is acceptable to supervise the cellular communication path just once daily.

Best Practices When Installing the TG-7FS as the Sole Path for a Commercial Fire System

• Use the TG-7FS multi-tower assessment feature to ensure that the unit can see multiple cellular towers for redundancy.
• Ensure the best possible cellular reception during installation.
• Achieving maximum reception may require high gain accessory antennas.

In the unlikely event of a cellular disruption lasting longer than 5 minutes, Telguard's TG-7FS must take the following actions (NFPA 72 2010, 14.2.7.2):

• Immediately trigger the supervisory trip output to indicate the loss of cellular connectivity.
• Immediately notify the central station of the disrupted connection.

System Integrator's responsibilities upon receiving the notification (NFPA 72 2010, 26.3.7.3):

• The dealer must dispatch a runner or maintenance person to arrive within two (2) hours to investigate.
• Notify the AHJ if the disruption exceeds eight (8) hours.
• Notify the subscriber or AHJ when the service has been restored if the disruption exceeded eight (8) hours.
