Quantity
- 10‑year sealed lithium battery Meets NYC DOB requirements and delivers uninterrupted protection for the full-service life, even during power outages. Providing maintenance‑free natural‑gas detection.
- Calibrated for early warning, sounding before natural gas reaches 8% LEL, providing faster detection than typical 25% LEL consumer alarms.
- Optimized ceiling‑level placement—designed to mount within 12 inches of the ceiling where methane accumulates first, ensuring earliest detection.
- 85 dB alarm with multi‑mode LED indicators, including dedicated red (gas detected), yellow (fault/low battery/end‑of‑life), and green (power) signals.
- Built‑in self‑diagnostics continuously monitor sensor health, battery status, and internal circuitry, alerting you to faults or end‑of‑life conditions.
- Advanced methane‑specific sensor detects only natural gas (CH₄), reducing nuisance alarms from unrelated gases or household contaminants.
- Wide environmental operating range, functioning reliably from 32°F to 122°F and up to 93% relative humidity.
- Flexible mounting options, including wall mounting near the ceiling or pipe mounting using cable ties for utility‑room installations.
- ETL Listed and tested to UL 1484, meeting the nationally recognized safety standard for residential natural‑gas alarms.
