Smart Shield Systems
FireFighter™ Sensor (2GIG-FF1E-345)
Add professional fire and CO alerting to homes that already have code-required smoke/CO alarms. The 2GIG-FF1E-345 is an encrypted audio “listening” sensor that mounts near an existing UL-listed smoke or CO detector and recognizes the alarm tones (Temporal-3 for smoke, Temporal-4 for CO). When it hears a valid pattern, it sends a wireless life-safety signal to your 2GIG panel and Alarm.com.
Why Choose This with Smart Shield Systems
- Right model, right panel: We deploy the encrypted eSeries FF1E-345 with GC2e/GC3e/EDGE panels, or the classic FF1-345 for legacy 345-MHz systems—then enroll and test both Smoke and CO reporting.
- Clean, code-aware placement: We mount the sensor within 6 inches of a UL smoke/CO alarm and verify tone recognition using manufacturer test procedures.
- Smart design for existing homes: If your wired smoke alarms are interconnected (one-go-all-go), one FireFighter can usually monitor the whole network; for non-interconnected alarms, we place one per device.
- Lifecycle & safety checks: We document battery type/expiry, show you weekly test steps, and schedule periodic functional checks.
Key Features
- Listens for UL tones: Recognizes Temporal-3 (smoke) and Temporal-4 (CO) patterns by default; optional generic mode is available for certain legacy non-temporal alarms.
- Dual reporting (Smoke + CO): Enroll two zones from one unit—Smoke uses the printed serial; CO uses serial + 1—so events display separately in your panel/app.
- Encrypted communication: eSeries AES-class security to the panel over 345 MHz.
- Fast, simple install: Mount within 6″ of the detector; bracket, screws, and tape included.
- Works with what you have: Does not change your existing UL alarms or their approvals.
Product Specifications (At-a-Glance)
- Model: 2GIG-FF1E-345 (eSeries, encrypted). Non-encrypted counterpart: 2GIG-FF1-345.
- What it does: Audio detector for UL smoke/CO alarms; sends Alarm / Supervisory / Low-Battery to the panel.
- Mounting distance: ≤ 6 inches from the smoke/CO detector’s sounder openings.
- Radio: 345.00 MHz (crystal-controlled); Equipment Code 2069 (2GIG). Supervisory interval ~64 min.
- Power: 1× CR123A 3 V lithium (1550 mAh); typical life ~3 years. Max current draw 23 mA (tx).
- Environment: 32–120 °F (0–49 °C); 5–95% RH, non-condensing. ABS, white. Listings: FCC/IC/ETL.
Compatibility Notes
- Panels: FF1E-345 requires a 2GIG eSeries panel (GC2e/GC3e/EDGE). Use FF1-345 on non-eSeries 2GIG/Honeywell-345 systems. We confirm during site survey.
- Interconnected vs. stand-alone alarms: With interconnected wired smokes, one FireFighter can cover the network; with non-interconnected units, install one per alarm.
- Important: FireFighter does not directly detect smoke, heat, fire, or CO—your existing UL alarms remain the primary detectors.
Popular Use Cases
- Retrofits where replacing every smoke/CO alarm with RF models isn’t practical
- Homes with hardwired, interconnected smokes—add professional monitoring with a single listener
- Add CO alerts from combo alarms to your security panel/app without rewiring
Frequently Asked Questions
By default it recognizes Temporal-3 (smoke) and Temporal-4 (CO) tones. We enroll two zones (Smoke & CO) so the panel and app show them separately.
Right next to the alarm—within 6 inches—and oriented so the FireFighter’s microphone holes face the alarm’s sounder openings.
Yes—there’s a generic listening mode for certain legacy alarms. We only use it when needed and follow the manual’s placement cautions.
If your wired smokes are interconnected (one-go-all-go), a single FireFighter can usually monitor the whole network. Otherwise, use one per stand-alone alarm.
We recommend weekly tests using the alarm’s test button (especially during the first hour after power-up when FireFighter is in test mode) and replacing the CR123A when the panel reports low battery.
