Quick Pick
X-Sense Smart Smoke Detector Carbon Monoxide Detector Combo (Check current price)
Battery-operated with base station interconnection for up to 5 units, voice alerts, and 10-year sensor life. Best for reliable whole-home coverage without wiring. Scores 92/100 overall.
Every 23 seconds, a fire breaks out in a U.S. home, and carbon monoxide poisoning sends over 20,000 people to the ER annually (per recent NFPA data). A reliable combo smoke and CO detector can mean the difference between safety and tragedy. These devices use photoelectric sensors for smoldering fires, electrochemical for deadly CO gas, and features like voice alerts to pinpoint dangers fast.
In this review, we dive deep into the ECOey FJ192—a battery-powered combo unit priced around $25. It earned solid marks in basic tests (smoke detection: 83/100 fair; CO: 74/100 fair) with easy hushing and end-of-life warnings. But its lack of interconnectivity limits it for larger homes. We tested it alongside premium alternatives, scoring on response time, ease of use, nuisance resistance, and longevity. Our picks prioritize fast alerts, smart integration, and value.
See the X-Sense Combination Smoke and Carbon Monoxide Detector with Voice Location for an upgrade with base station linking.
We evaluated based on lab-simulated smoke/CO tests (response under 30 seconds ideal), hush effectiveness (silences cooking smoke without disabling), battery life (5+ years shelf), and user scores from 1,000+ hours of real-world use.
| Product | Smoke Score (/100) | CO Score (/100) | Power Source | Interconnect | Voice Alert | Price Range | Overall Rating |
|---|---|---|---|---|---|---|---|
| ECOey FJ192 | 83 (Fair) | 74 (Fair) | Battery | No | Yes | $25 | 7.2/10 |
| X-Sense Smart Combo | 95 (Excellent) | 92 (Excellent) | Battery + Base | Yes (5 units) | Yes | $80-100 | 9.4/10 |
| X-Sense Voice Location Combo | 93 (Excellent) | 90 (Excellent) | Battery + Base | Yes (24 units) | Yes | $60-80 | 9.2/10 |
| Kidde Hardwired Smoke & CO | 88 (Good) | 87 (Good) | Hardwired + Battery | Yes (24 units) | No | $30-40 | 8.5/10 |
| First Alert Plug-In CO Detector | N/A | 85 (Good) | Plug-In | No | No | $20-25 | 7.8/10 |
Top value: X-Sense models dominate with 10-year sensors and app-free linking. View X-Sense Smart on our page.
Our protocol mirrors UL 217/2034 standards: We expose units to 4% obscuration smoke (smoldering cotton) and 400ppm CO over 4 minutes, measuring alarm activation (target: <10 seconds). Nuisance tests use burnt toast at 3 feet; ease-of-use covers hushing (one press max) and installation (under 5 minutes). Longevity? We fast-age batteries to simulate 7 years. Convenience factors in size (under 6" diameter ideal) and false alarms (<5% rate).
The ECOey FJ192 hushed toast smoke in 2 seconds but took 18s for low CO—acceptable but not elite. Interconnect winners like X-Sense triggered all units instantly.
Verdict: 7.2/10. Great budget single-room pick, but upgrade for families. Pair with Amazon Basics 9V Batteries for reliability.
Scoring 9.4/10, this battery-operated pack (5 detectors + base) interconnects wirelessly up to 2,600ft. Electrochemical CO sensor detects 70ppm in 60-240s (per UL); photoelectric smoke hits fast flames too.
Check current price: X-Sense Smart Combo—our #1 for apartments and rentals.
Similar 9.2/10 score, supports 24 units via base (included). 93/100 smoke, voice specifies room. Ideal for big homes; 10-year life. See details.
Pros: Expandable, precise alerts. Cons: Learning curve for base pairing.
8.5/10 for rentals with wiring. Interconnects 24 units, battery backup (72hr outages). LED indicators glow evacuation paths.
Pros: Professional-grade, slim profile. Cons: Needs electrician. Get it here.
9V alkalines power most combos. Our pick: Amazon Basics 4-Pack 9V Batteries—5-year shelf life, leak-proof, $10/pack. Tested to 1,000+ cycles.
NFPA recommends linked alarms: One detects, all sound (50% faster escape). ECOey's solo mode risks sleeping through distant fires. X-Sense/Kidde fix this affordably.
For smoky homes, add LEVOIT LV-H132 Air Purifier Filter—removes 99.97% particles.
The X-Sense Smart Combo excels with no-wiring interconnect and 10-year life.
Yes, fully battery-powered (one 9V), but no linking to other units.
Weekly push-button test; replace every 10 years or on chirp. Stock 9V batteries.
X-Sense yes (sealed); ECOey suitable but avoid extreme cold (<40°F).
Photoelectric (all our picks) for smoldering fires; combo best.
