Sensitron support FAQ

Common questions about manuals, registration, and support for this brand.

  • What gases can Sensitron detectors detect?

    Sensitron gas detectors are designed to sense a wide variety of flammable, toxic, and refrigerant gases, including methane, propane, butane, carbon monoxide, nitrogen dioxide, and more.

  • Where should I position my Sensitron flammable gas detector?

    Gases heavier than air (e.g., LPG, butane) require detectors placed 30 cm from the floor, while lighter-than-air gases (e.g., methane) require detectors placed about 30 cm from the ceiling.

  • How often does my Sensitron gas detector need calibration?

    With pellistor or electrochemical sensors, a biannual check is recommended. Infrared sensors typically require an annual performance check. Always refer to your specific model's manual.

  • What does a yellow LED mean on a Sensitron SMART detector?

    A yellow LED on the detector panel normally indicates a fault condition. Check power connections, sensor life, and assure the appropriate voltage is reaching the detector.
