2GIG FF-345 FireFighter Wireless Smoke CO Listener-Transmitter 345MHz

The 2GIG FF-345 FireFighter is a wireless audio listener-transmitter designed to expand life safety coverage by monitoring existing hardwired smoke and carbon monoxide detectors. This non-invasive device passively listens for the distinct alarm cadences of UL-listed smoke and CO detectors, then transmits wireless alerts to compatible 345 MHz control panels for immediate notification. No modification to existing detectors is required, preserving all UL and Fire Marshall certifications.

Powered by a single CR123A lithium battery, the FF-345 delivers up to five years of maintenance-free operation. It mounts easily within 6 inches of any hardwired detector and is ideal for retrofitting residential and small commercial properties with wireless life safety integration. The device transmits a supervisory signal approximately every 62 minutes to confirm reliable operation.

Fully compatible with 2GIG panels (GC2, GC3) and Honeywell 5800 Series unencrypted receivers, the FF-345 operates across temperatures from 32°F to 120°F with 5–95% non-condensing humidity. ETL listed to UL985 and ULC-S545 standards for safety compliance in the US and Canada.
