First Alert CO410 Carbon Monoxide Detector Alarm User Manual

1. Introdução

The First Alert CO410 Carbon Monoxide Alarm is designed to detect carbon monoxide (CO) gas, a colorless, odorless, and tasteless gas that can be deadly. This battery-operated unit provides continuous monitoring of CO levels, even during power outages, and features a backlit digital display for easy viewing of current and peak CO concentrations. An 85-decibel alarm sounds when CO levels reach dangerous thresholds. The device includes an EZ access battery door for convenient battery changes and an optional wall mount for flexible placement.

2. Informações importantes de segurança

Carbon monoxide (CO) is a highly toxic gas produced by the incomplete combustion of fuels. It is impossible to detect with human senses. CO alarms are crucial for early warning of CO presence. This device is intended to detect carbon monoxide gas from any source of combustion. It is not designed to detect smoke or fire.

Sources of Carbon Monoxide:

• Unvented gas or kerosene heaters
• Leaking chimneys or furnaces
• Gas ranges, water heaters, clothes dryers
• Geradores portáteis
• Fireplaces, wood-burning stoves
• Automobiles running in an attached garage

Sintomas de envenenamento por monóxido de carbono:

Symptoms of CO poisoning are often mistaken for the flu and include headache, dizziness, nausea, vomiting, and fatigue. Prolonged exposure can lead to collapse, unconsciousness, and death. If you suspect CO poisoning, seek fresh air immediately and call emergency services.

3. Configuração

3.1. Instalação da bateria

1. Open the EZ access battery door located on the front of the unit.
2. Insert two (2) AA batteries, ensuring correct polarity (+ and -).
3. Feche a porta da bateria com segurança.
4. The unit will perform a self-test and indicate readiness.

3.2. Montagem da Unidade

The CO410 can be placed on a flat surface or wall-mounted. For wall mounting:

1. Choose an appropriate location (refer to "Placement Guidelines" section).
2. Utilize os parafusos e buchas fornecidos para fixar o suporte de montagem na parede.
3. Align the back of the CO410 unit with the mounting bracket and twist clockwise until it locks into place.

4. Instruções de operação

4.1. Display digital

The backlit digital display shows the current carbon monoxide concentration in parts per million (PPM). In normal operation, it may show "0 PPM" or a low background level. The display will illuminate when a button is pressed or during an alarm event.

4.2. Botão de teste/silenciamento

Pressione e segure o TESTE/SILÊNCIO button to test the alarm's functionality. The alarm will sound a loud 85-decibel horn, and the display will show a test pattern. Release the button to stop the test. This button can also silence a non-threatening alarm or a low battery warning chirp.

4.3. Peak Level Memory

Pressione o NÍVEL DE PICO botão para view the highest CO concentration detected by the alarm since its last reset or power-up. This feature is useful for monitoring potential intermittent CO issues. The peak level will be displayed in PPM.

5. Manutenção

5.1. Testes regulares

Test your CO alarm weekly by pressing the TESTE/SILÊNCIO button. This ensures the unit is functioning correctly. If the alarm does not sound during the test, replace the unit immediately.

Figure 6: Regularly testing your carbon monoxide alarm is essential for safety.

5.2. Substituição da bateria

The CO410 uses two (2) AA batteries. When the batteries are low, the unit will chirp periodically and display a low battery indicator. Replace batteries promptly to ensure continuous protection. Use only recommended alkaline batteries.

5.3. End-of-Life Warning

The CO410 has a 7-year limited warranty and is designed to last approximately 7 years. After this period, the unit will emit an end-of-life signal chirp, indicating it's time to replace the entire alarm for continued safety.

Figure 7: Replace carbon monoxide alarms at least every 7 years.

6. Diretrizes de Colocação

For optimal protection, install carbon monoxide alarms on every level of your home and in each sleeping area. Consider placing additional alarms near potential CO sources like furnaces, water heaters, and attached garages.

7. What to Do in Case of an Alarm

If the carbon monoxide alarm sounds:

1. Vá imediatamente para um local com ar fresco ao ar livre ou abra todas as portas e janelas.
2. Faça uma contagem para verificar se todas as pessoas estão presentes.
3. Do not re-enter the premises until the building has been aired out and the alarm remains in its normal condition.
4. Ligue para os serviços de emergência (Corpo de Bombeiros ou 911).
5. Call a qualified appliance technician to investigate the source of CO from fuel-burning equipment and appliances, and inspect for proper operation of this equipment.

8. Solução De Problemas

• Alarm Chirps Periodically: This usually indicates a low battery. Replace the batteries immediately.
• Alarm Does Not Sound During Test: Ensure batteries are correctly installed and fresh. If the issue persists, the unit may be faulty and requires replacement.
• Leituras Erráticas: Ensure the alarm is not placed near vents, windows, or in areas with high humidity or extreme temperatures, which can affect sensor performance.
• Alarm Sounds Without Apparent CO: Evacuate the premises and call emergency services. Even low levels of CO can be dangerous.
