Telguard TG-7FS LTE-A AT&T Commercial Fire Cellular Alarm Communicator

The Telguard TG-7FS LTE-A (Commercial Fire Cellular Alarm Communicator) is a robust code-compliant solution engineered for commercial fire alarm systems, enabling cellular transmission of alarm signals via the AT&T LTE (or LTE-M) network. It is certified to standards such as UL 864 for sole-path, primary or backup communication, eliminating the need for dedicated landlines. With automatic self-tests, dual supervision modes (5-minute or 60-minute) and fallback to earlier 3G/4G if LTE is unavailable, it delivers continuous reliability and improved building penetration. The unit supports universal alarm panel formats (Contact ID, SIA2, pulse 3×1/4×2, DMP, modem IIe/IIIa) and reports full data back to monitoring stations. A sturdy red-metal locking enclosure mounts easily on commercial systems and accommodates single-path and dual-path deployment. With power draw in standby around 40-60 mA and transmission around 160-250 mA, it is efficient and designed to integrate into typical fire panel auxiliary power circuits. The communicator includes two programmable supervisory trip outputs, built-in telephone line monitor and sliding scale supervision modes to meet varying jurisdiction requirements. Installation is straightforward, transforming fire system communications to modern cellular paths with greater flexibility, lower recurring costs and compliance for modern fire-alarm infrastructures.
