FireFighter™ Sensor (2GIG-FF1E-345)

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

How does it “hear” both smoke and CO?

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.

Where exactly do you mount it?

Right next to the alarm—within 6 inches—and oriented so the FireFighter’s microphone holes face the alarm’s sounder openings.

Can it work with older, non-temporal alarms?

Yes—there’s a generic listening mode for certain legacy alarms. We only use it when needed and follow the manual’s placement cautions.

Will one unit cover my whole house?

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.

What maintenance is required?

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.

Ready to Add Monitored Fire & CO Alerts?

Smart Shield Systems will specify the correct FireFighter™ (2GIG-FF1E-345) or FF1-345, place it to spec, enroll Smoke + CO zones, and test everything—so your existing alarms can also notify your security system and monitoring team.
