1. Introduction
This manual provides essential information for the proper installation, operation, and maintenance of your HEIMAN Carbon Monoxide (CO) Detector Alarm 722ES. This device is designed to detect carbon monoxide gas and alert occupants to potentially dangerous CO levels, helping to ensure the safety of your home or premises. Please read this manual thoroughly before using the detector and retain it for future reference.
2. Safety Information
Carbon monoxide (CO) is a colorless, odorless, and tasteless gas that can be fatal. This detector is designed to alert you to the presence of CO, but it is not a substitute for proper maintenance of fuel-burning appliances or adequate ventilation.
2.1 Important Warnings
- This CO detector is designed for indoor use only.
- Do not paint the detector. Paint can block the sensor openings and interfere with the detector's ability to detect CO.
- Regularly test the detector as instructed in this manual.
- Do not install in areas with high humidity, extreme temperatures, or excessive dust.
- This detector is not suitable for detecting smoke, fire, or other gases.
2.2 Sources of Carbon Monoxide
Carbon monoxide can be produced by any fuel-burning appliance or engine. Common sources include:
Image: Sources of Carbon Monoxide. This image illustrates various common sources of carbon monoxide, including car exhaust, burning charcoal, coal, and natural gas used in cooking. These sources can produce dangerous levels of CO if not properly ventilated.
- Car exhaust from attached garages.
- Charcoal grills and portable generators used indoors.
- Malfunctioning or unvented fuel-burning appliances (furnaces, gas ranges, water heaters, fireplaces).
- Blocked chimneys or flues.
2.3 Effects of Carbon Monoxide Exposure
Exposure to carbon monoxide can cause various symptoms depending on the concentration and duration of exposure. High concentrations can be fatal.
Image: Effects of Carbon Monoxide Exposure. This chart details the physiological effects of carbon monoxide exposure at various concentrations and durations. For example, 400ppm can cause frontal headaches within 1-2 hours, becoming life-threatening after 3 hours. Higher concentrations like 12800ppm can lead to death within 1-3 minutes.
- 30ppm: Alarm after 120 minutes.
- 50ppm: Alarm after 60-90 minutes.
- 100ppm: Alarm after 10-40 minutes.
- 300ppm: Alarm after 3 minutes.
- 400ppm: Frontal headaches within 1-2 hours, life threatening after 3 hours.
- 1600ppm: Headache, dizziness and nausea within 20 minutes. Death within 1 hour.
- 6400ppm: Headache, dizziness and nausea within 1-2 minutes. Death within 10-15 minutes.
- 12800ppm: Death within 1-3 minutes.
3. Product Overview

4. Setup
4.1 Battery Installation
The detector is powered by 2 x AA LR6 DC 1.5V alkaline batteries (included). Ensure correct polarity when inserting batteries. The device has a special tamper-resistant design that prevents installation without batteries.
4.2 Mounting Location
Proper placement is crucial for effective CO detection. Carbon monoxide is slightly lighter than air and mixes readily with air. Install the alarm at 0.3 to 1 meter (approximately 1 to 3.3 feet) below the ceiling.
- Wall Mounting: Use the provided mounting bracket, screws, and dowels.
- Table Placement: The detector can also be placed on a flat surface.
Image: Wall Hanging. This image demonstrates the HEIMAN Carbon Monoxide Alarm mounted on a wall, illustrating a typical installation scenario.
4.3 Initial Test
After installation, press the 'TEST/HUSH' button to confirm the alarm is functioning correctly. The alarm should sound, and the red LED should flash.
5. Operating
5.1 Normal Operation
In normal operating conditions, the green 'POWER' indicator light will flash approximately every 30 seconds, indicating the detector is functioning correctly.
5.2 Alarm Conditions
When hazardous levels of carbon monoxide are detected, the detector will activate its alarm:
- The red 'ALARM' LED will flash.
- The horn will sound a loud alarm (≥85dB at 1m).
The alarm will automatically reset when the CO level returns to a safe level.
5.3 Test/Hush Function
Press the 'TEST/HUSH' button to:
- Test: Verify the alarm's functionality.
- Hush: Temporarily silence the alarm for a short period if a known, non-emergency CO source is present (e.g., temporary high CO from a gas stove). The alarm will reactivate if CO levels remain high.
6. Maintenance
6.1 Battery Replacement
The detector is equipped with 2 x 1.5V AA batteries designed for a service life of up to 5 years. When the batteries are low:
- The yellow 'FAULT' indicator will flash.
- The LCD display (if present on your model) will show "000".
- The device will beep "of" every 10 seconds.
Replace both batteries immediately with new AA LR6 DC 1.5V alkaline batteries.
6.2 General Care
- Clean the detector regularly with a soft, damp cloth. Do not use cleaning agents or solvents.
- Do not paint the detector.
- Ensure the sensor openings are free from dust and debris.
7. Troubleshooting
| Problem | Indication | Solution |
|---|---|---|
| Low Battery | Yellow indicator flashes, LCD shows "000", device beeps "of" every 10 seconds. | Replace both AA batteries immediately. |
| Fault/Malfunction | Yellow indicator is always on, LCD shows "Err", device beeps "didi" every 10 seconds. | The device has detected an internal fault. Try replacing batteries. If the fault persists, the unit may need replacement. |
| Alarm Sounds (Red LED flashing) | Loud alarm (≥85dB), red LED flashes. | DO NOT IGNORE THE ALARM. Immediately move to fresh air. Call emergency services if symptoms persist. Do not re-enter the premises until the source of CO has been identified and corrected, and the area has been ventilated. |
| No Power Indicator (Green LED off) | No green light flashing every 30 seconds. | Check battery installation. Replace batteries if necessary. If still no power, the unit may be faulty. |
