Product Features
- 4-in-1 Sensor Technology: Integrates detection for combustible gas, carbon monoxide, temperature (°F), and humidity.
- Advanced Sensing: Utilizes catalytic combustion sensor for combustible gas and an electrochemical sensor for carbon monoxide, providing accurate and sensitive detection.
- Real-time Digital Display: Features an upgraded round color screen for clear, simultaneous display of all monitored parameters.
- High-Decibel Alarm: Emits an 85dB alarm sound when gas or carbon monoxide concentrations reach predefined alert levels.
- Plug-and-Play Design: Simple installation by plugging directly into a standard electrical outlet.
Setup and Installation
The Hembisen Gas & Carbon Monoxide Detector is designed for easy plug-in installation. Follow these guidelines for optimal placement and setup:
- Unpack the Device: Carefully remove the detector from its packaging.
- Choose a Location:
- For combustible gas (e.g., natural gas, propane): Install the detector within 10 feet of potential leak sources (e.g., gas stoves, water heaters, furnaces). Natural gas is lighter than air, so place it higher on the wall. Propane is heavier than air, so place it lower.
- For carbon monoxide: Install the detector in areas where CO may accumulate, such as near sleeping areas, living rooms, or any room with fuel-burning appliances.
- Avoid placing the detector in direct sunlight, near vents, fans, or in areas with high humidity or extreme temperatures.
- Plug In: Insert the detector directly into a standard electrical outlet. The plug can rotate for flexible installation.
- Initial Power-On: Upon plugging in, the device will perform a self-check and display readings.

Operating Instructions
Once plugged in, the detector continuously monitors the environment. Here's how to understand its operation:
- Display Readings: The color screen will show real-time readings for:
- Temperature in Fahrenheit (°F)
- Carbon Monoxide (CO) in PPM (Parts Per Million)
- Combustible Gas (GAS) in %LEL (Lower Explosive Limit)
- Relative Humidity (RH%)
- Indicator Lights:
- POWER: Green light indicates the device is powered on and functioning normally.
- FAULT: Orange light indicates a fault or malfunction. Refer to troubleshooting.
- ALARM: Red light flashes and the alarm sounds when gas or CO levels exceed safe thresholds.
- Self-Test Button: Press the "SELF-TEST" button to manually test the alarm function. The device will emit the alarm sound and flash lights. This should be done regularly to ensure proper operation.

Maintenance
To ensure the longevity and accuracy of your Hembisen detector, follow these maintenance tips:
- Regular Cleaning: Gently wipe the exterior of the detector with a soft, dry cloth. Do not use cleaning sprays, solvents, or abrasive cleaners, as these can damage the sensors or trigger false alarms.
- Keep Vents Clear: Ensure that the air inlets and outlets on the device are not obstructed by dust, debris, or other objects.
- Avoid Chemical Exposure: Do not spray aerosols, perfumes, colognes, or cleaning products directly near the detector, as these can cause temporary false alarms due to their chemical composition.
- Monthly Self-Test: Press the "SELF-TEST" button monthly to verify the alarm's functionality.
