Carbon Monoxide Alarms NZ – Essential Home Safety Protection

Frequently Asked Questions

• Where should I install a CO alarm in my home?
  Install carbon monoxide detectors near sleeping areas and fuel-burning appliances. Ideal locations include bedrooms, hallways outside bedrooms, living rooms with heaters or fireplaces, and attached garages.
• What are the signs of carbon monoxide poisoning?
  Common symptoms include headaches, dizziness, nausea, fatigue, shortness of breath, and confusion. Because these symptoms are similar to flu, carbon monoxide poisoning can often go unnoticed without a CO alarm.
• What causes carbon monoxide in a home?
  Carbon monoxide is produced when fuels such as gas, wood, coal, petrol, or diesel do not burn completely. Common sources include gas heaters, wood burners, fireplaces, generators, and vehicles running in enclosed or poorly ventilated areas.
• Do CO alarms detect smoke or fire?
  No. Carbon monoxide alarms only detect CO gas. They do not detect smoke or fire. For full protection, many homeowners choose combination smoke and CO alarms or install both separately.
• Are wireless interlinked CO alarms worth it?
  Yes. Wireless interlinked carbon monoxide alarms provide faster warning because when one alarm detects danger, all alarms in the system sound at the same time. This is especially useful in larger homes, multi-storey properties, and rental accommodations.
• How often should I test my CO alarm?
  You should test your carbon monoxide alarm at least once a month using the test button to ensure it is working correctly. Regular testing helps ensure reliable performance in an emergency.
• Can I install a CO alarm myself?
  Yes, most battery-powered and wireless CO alarms are designed for easy DIY installation. They can usually be mounted with screws or adhesive backing without needing an electrician.
• What is the difference between a smoke alarm and a CO alarm?
  A smoke alarm detects smoke particles from fire, while a carbon monoxide alarm detects invisible CO gas produced by fuel burning. Both are important for complete home safety, but they serve different purposes.
