Firlarm 2-in-1 Gas Leak & CO Detector Plug-in with LED Display – 85dB Alarm

Smart, continuous protection for homes and travel

The Firlarm Gas and CO Detector combines a 2-in-1 sensor with a clear LED display, delivering real-time readings for both gas and carbon monoxide. Gas readings read 0–9% LEL while CO reads 0–999 ppm, making it easy to interpret levels at a glance.

In everyday terms, this means you can see a running running snapshot of your air quality—helping you notice changes quickly, whether you’re cooking, running a heater, or resting at night.

Immediate alarm when danger is detected

When concentrations reach the detectors' thresholds, a flashing red light and an 85 dB alarm activate to grab attention. The display also indicates gas as AAA or CO spikes, supporting a fast, informed response.

• 2-in-1 sensing covers two common hazards in one compact device.
• LED readouts translate measurements into actionable information.
• Audible and visual alerts aim to wake you and others, even from deep sleep.

Designed for versatile placement, it suits kitchens, bedrooms, garages, basements, apartments, and even travel scenarios where power outlets are available. The unit plugs into 110V–220V AC, drawing only about 2W, which helps keep energy usage low while maintaining readiness.

• Plug-and-play design enables quick setup with minimal tools or fuss.
• Flame-retardant PC housing resists dirt and grease for better long-term reliability.
• 120-second warm-up ensures the sensor stabilizes before normal operation.

Operational guidance is simple. After plugging in, allow the warm-up to complete, then press Test to trigger the alarm. When in normal operation, the screen shows zero, the yellow indicator stays steady, and the red indicator may flash with continuous buzzer if an alarm occurs.

For households with children, seniors, or expectant parents, proactive awareness can be particularly reassuring. Its compact size and reliable readings make it easy to integrate into daily routines and safety checks.
