2GIG 345S Firefighter Smoke And Co Detector Listener (2GIG-FF100-345)

2GIG-FF100-345 | FireFighter™ Smoke and CO Alarm Listener Wireless Protocol: 345 MHz | Battery Life: 5 Years The 2GIG FireFighter is the fastest, most cost-effective way to add 24/7 fire monitoring to your home security system. Instead of replacing your existing smoke detectors, this sensor listens for the specific UL-listed alarm cadence (Temporal 3 for Smoke, Temporal 4 for CO). Once it hears your current alarms sounding, it instantly sends a wireless signal to your 2GIG or Honeywell-compatible control panel.

Key Features Universal Monitoring: Works with any existing UL-listed smoke, CO, or combination detectors without affecting their Fire Marshall approval. Smart Supervision: Sends a supervisory signal to the panel every 64 minutes to ensure the sensor is online and functional. Long-Range Detection: Specifically tuned to recognize alarm cadences within a 6-inch maximum distance from the siren.

Secure Transmission: 345 MHz crystal-controlled transmitter with optional encryption enabled via an onboard switch. Complete Kit: Includes a long-life lithium battery and a full mounting package for immediate installation.
