• Audible and Visual Alarms: Provides an 85 dB audible alarm and visual indicators for detected hazards.

3. Safety Information

Understanding the hazards associated with carbon monoxide, combustible gases, and smoke is crucial for your safety.

Image 3.1: Overview of the hazards associated with carbon monoxide, combustible gas, and smoke.

3.1 Carbon Monoxide Hazard

Carbon monoxide is a colorless, odorless, and toxic gas. Mild poisoning symptoms include headaches, dizziness, palpitations, nausea, vomiting, limb weakness, and brief fainting. Inhaling high concentrations can lead to coma, collapse, or death. It can harm the brain, heart, liver, kidneys, lungs, and other tissues.

3.2 Combustible Gas Hazard

Natural gas is a colorless, odorless, non-toxic, and non-corrosive gas. While methane itself is not harmful to humans, it can cause suffocation by displacing oxygen. Gas leaks can also emit toxic carbon monoxide, leading to dizziness, poisoning, or death. A concentration of 10% natural gas in the air poses a risk of suffocation and poisoning reactions.

3.3 Smoke Hazard

Thick smoke contains harmful particles such as carbon monoxide, sulfur dioxide, and nitrogen oxides. Inhaling smoke during a fire can irritate respiratory passages, causing coughing, chest tightness, and shortness of breath. Excessive smoke inhalation can lead to damage to the nervous and cardiovascular systems.

4. Setup and Installation

4.1 Initial Setup

The Gedsffati HD11 detector is designed for plug-and-play operation. Simply plug the device into a standard 110V to 240V AC outlet. The device will automatically begin monitoring once powered.

4.2 Placement Guide

Proper placement of the detector is essential for effective monitoring. Consider the following guidelines for optimal installation:

• Install detectors in bedrooms, living rooms, kitchens, basements, and garages.
• For CO detection, place at breathing height, typically near sleeping areas.
• For smoke detection, place on ceilings or high on walls, away from corners.
• For combustible gas detection, place near potential sources of gas leaks (e.g., gas stoves, water heaters).
• Avoid placing near windows, doors, or vents where air currents might dilute gas concentrations.
• Avoid placing in areas with high humidity or extreme temperatures.

5. Operation

5.1 Understanding the Display

The 2.1-inch HD screen provides clear, real-time information about your environment. Key indicators include:

• CO PPM: Carbon Monoxide concentration in parts per million.
• GAS Icon: Indicates combustible gas detection.
• SMOKE Icon: Indicates smoke detection.
• Temperature: Current ambient temperature.
• Humidity: Current ambient humidity level.
• Battery Icon: Shows battery charge level.
• Buzzer Status: Indicates if the alarm buzzer is active.
• Plug Icon: Indicates if the device is connected to AC power.

5.2 Button Functions

• Power Button (Large central button):
  • Short press: Initiates self-testing.
  • Long press: Turns off the device when operating on battery power.
• Screen Brightness Button (Left button):
  • Short press: Changes screen brightness level.
  • Long press: Switches temperature display between Celsius (°C) and Fahrenheit (°F).
• Buzzer Button (Right button):
  • Short press: Turns off the alarm buzzer.

5.3 Self-Test Function

It is recommended to test the detector regularly to ensure proper functionality.

1. Button Test: Short press the Power button to initiate a self-test. The device will perform a system check and sound the alarm briefly.
2. Smoke Test: To test the smoke sensor, approach the detector with smoke from an unburned paper or a cigarette. The CO value on the screen will change, and the alarm will sound 'di di di' when reaching the alarm value. Note: Do not test with car exhaust or burning gas in open areas, as low CO values may not trigger the sensor.

6. Alarms and Indicators

The detector uses both audible and visual cues to alert you to potential dangers.

• Green Light Indicator: When the screen is off and the indicator light is green, it signifies normal operation and continuous monitoring of smoke, combustible gas, and CO concentrations.
• Red Light Indicator / Alarm: A red light and an audible alarm indicate a detected hazard (smoke, CO, or combustible gas) or a sensor malfunction. The alarm sound level is typically over 85 dB.

7. Maintenance

7.1 Battery Information

The device includes a built-in 2000 mAh rechargeable lithium-ion battery. This battery provides approximately 18-20 hours of operation during power outages, ensuring continuous protection. The rechargeable design eliminates the need for frequent battery replacements, saving costs.

7.2 Cleaning

To maintain optimal performance, regularly clean the exterior of the detector with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners. Ensure that the sensor openings are free from dust and debris.

8. Troubleshooting

If the detector is not functioning as expected, consider the following:

• No Display/Power: Ensure the device is securely plugged into a working AC outlet. If operating on battery, check the battery level.
• False Alarms: Ensure the detector is not placed near sources of steam, cooking fumes, or excessive dust. Relocate if necessary.
• Alarm Sounds Continuously: If an alarm sounds and there is no apparent hazard, ventilate the area and perform a self-test. If the alarm persists, contact customer support.
• Red Light Indicator (Malfunction): If the red light indicates a malfunction, perform a self-test. If the issue is not resolved, the sensor may require service or replacement.
