Posted by Emergency Electricians Adelaide on 10 Nov 2025

Smoke alarms are a crucial security measure in every home. They are designed to detect fire or smoke and notify you of the danger, and allow you to get your home out of danger and call for assistance. Based on the National Fire Protection Association (NFPA), nearly three out of five home fire deaths result from the fires in homes without smoke alarms or working smoke alarms. Therefore, it’s important to have a functioning smoke alarm in each bedroom, outside each sleeping space, and on every level of your home, which includes the basement.

Smoke Alarms for Ionization

Smoke alarms that use Ionization utilize only a tiny amount of radioactive material to ionize the air inside the alarm. If smoke gets into the alarm, it interrupts the process of ionization and causes an alarm sound to be heard. Smoke alarms of this type are good at detecting fast, flaming fires and generally are less costly in comparison to photoelectric fire alarms.

However, smoke alarms that use ionization aren’t as effective in detect slow burning fires. They are also more vulnerable to false alarms from steam or cooking, which can be frustrating for homeowners. Ionization smoke alarms should be used in areas where there are none of the cooking equipment, such as hallways and bedrooms.

Photoelectric Smoke Alarms

Smoke alarms using photoelectric technology use the use of light beams for detecting smoke. If smoke gets into the alarm it scatters light, which causes the alarm to sound. These types of smoke alarms are effective in detect slow burning fires and are less vulnerable to false alarms caused by cooking or steam.

But photoelectric smoke alarms are not as effective in detecting rapid burning fires. They’re also more expensive than ionization alarms. Photoelectric smoke alarms are best utilized in places where there are cooking appliances, for example, kitchens and living spaces.

Dual Sensor Smoke Alarms

Dual-sensor smoke alarms blend both ionization and photoelectric sensors to offer the most comprehensive fire detection. They can detect both fast, flaming fires and slow burning fires and are less susceptible to false alarms than photoelectric or ionization smoke alarms on their own.

However, Dual sensor smoke alarms are typically more expensive than photoelectric or ionization smoke alarms by themselves. Dual sensor smoke alarms should be used when both quick, flaming fires and slow burning fires are feasible for example, bedrooms and living spaces.

Smart Smoke Alarms

Smart smoke alarms are linked to the Wi-Fi network in your home and will send out notifications to your smartphone or other devices if they spot smoke or fire. They also can be integrated with other smart home devices, for example, smart thermostats and security alarms.

Smart smoke alarms are effective in providing instant alerts even when you’re away from at home. However, they are typically higher priced than conventional smoke alarms, and require an internet connection that is reliable to work properly.
