Posted by Local Electrician Randwick on 13 May 2024

Smoke alarms are an important security measure in every home. They are made to detect fire or smoke and alert you to the danger, and allow you to get your home out of danger and call for assistance. Based on the National Fire Protection Association (NFPA) almost three out of five house fire deaths occur due to fires in homes with no smoke alarms, or with no functioning smoke alarms. So, it’s crucial to have a working smoke alarm in every bedroom, in all sleeping areas and on every floor of your house, including the basement.

There are many kinds of smoke alarms in the marketplace, all having their particular pros and pros and. Understanding the distinctions between them can help you select the most suitable one for your home.

Smoke Alarms with Ionization

Ionization smoke alarms use a small amount of radioactive material to ionize air within the alarm. When smoke enters inside the detector, it disrupts the process of ionization and causes the alarm to sound. These kinds of smoke alarms are effective in detecting rapid burning fires and generally cost less than photoelectric smoke alarms.

However, smoke alarms that use ionization aren’t as effective in detect slow burning fires. They are also more prone to false alarms due to steam or cooking which can be a hassle for homeowners. Smoke alarms that ionize are best employed in areas with kitchen appliances that are not in use, like hallways and bedrooms.

Photoelectric Smoke Alarms

Smoke alarms using photoelectric technology use a beam of light that detects smoke. When smoke enters the alarm, it scatters the lightand causes it to sound. Smoke alarms of this type are excellent at detect slow burning fires and are less vulnerable to false alarms caused by steam or cooking.

But, photoelectric smoke alarms are not as effective at detecting quick, flaming fires. They are also generally more expensive than ionization-based smoke alarms. Smoke alarms that are photoelectric can be utilized in places in which there are cooking appliances, for example, kitchens and living spaces.

Two Sensor Smoke Alarms

Dual-sensor smoke alarms combine photoelectric and ionization sensors to offer the most comprehensive fire detection. They are good at detecting both fast, flaming fires and slow, smoldering flames, and are less susceptible to false alarms than ionization or photoelectric smoke alarms on their own.

However, smoke detectors with dual sensors are typically more expensive than photoelectric or ionization smoke alarms on their own. Dual sensor smoke alarms should be employed when both quick flames, flaming fires as well as slow, smoldering fires are possible like bedrooms and living spaces.

Smart Smoke Alarms

Smart smoke alarms are connected to your home’s Wi-Fi network and will send out notifications to your smartphone or any other device when they detect fire or smoke. They are also able to be connected with other smart home devices for example, smart thermostats as well as security devices.

The smart smoke alarms can be effective for providing alerts in real-time even when you’re not at home. They are, however, generally more expensive than traditional smoke alarms, and require an active Wi-Fi connection in order to function correctly.
