The SHIELD SD6200 is specifically designed to detect Methane (natural gas) for household safety applications.
Both the detector and the sensor have a typical operational lifespan of 5 years. The device features an automatic end-of-life warning when replacement is needed.
When gas concentration reaches 10% LEL, the red light remains constantly lit, rapid chirping sounds, and automatic linkage output is activated. Pressing the self-test button can temporarily mute the alarm.
The detector is wall-mounted and comes complete with an installation hanging plate and screw kit for quick household installation.
Simply press the "Self-test" button under normal conditions. The unit will run a 10-second audio-visual check with cyclical flashing lights, continuous beeping, and linked output test.
Yes, it operates on AC220V power and offers EU, US, UK, AU plug choices, along with optional NB-IoT or 4G communication modules for mobile alarm push notifications.
