DC 3V Smoke Detector with 85dB Alarm and Self-Check

Add a battery-powered smoke alarm to a suitable indoor location. Quantity options help you plan how many units you need.

Check and maintain your smoke alarm

✅ Hear a smoke alert with the listed sound output of at least 85dB at three metres.

✅ Check operation using the self-check function.

✅ Temporarily silence an alert with the approximately ten-minute silence mode.

The supplied specifications list a photoelectric sensor and DC 3V power. The stated coverage range is 20–40m²; compare the installation guidance with the space being monitored.

The listed operating range is 0°C to 55°C with humidity up to 95%. The sensor lifespan is stated as up to ten years; that is a sensor specification rather than a ten-year battery-life claim.
