2GIG FF100-345 - Data Sheet (2025)

The 2GIG
®
FireFighter is a quick and easy way to add
smoke alarm monitoring to your 2GIG control panel.
FireFighter is specifically tuned to recognize the
specific cadence of a UL listed smoke or CO detector’s
alarm. This unique audio technology monitors existing
UL listed smoke detectors in a home and will send
a wireless signal to the control panel when an alarm
is detected. The control panel will then contact the
connected central monitoring station.
