Ionization Smoke Alarms

Smoke alarms that use Ionization utilize some radioactive material to ionize air in the alarm. If smoke gets into the alarm, it disrupts the ionization process, causing an alarm sound to be heard. These kinds of smoke alarms are good at detecting fast, flaming fires and generally cost less than photoelectric smoke alarms.

But, ionization smoke alarms are not as effective at detecting slow, smoldering fires. They also are more susceptible to false alarms from steam or cooking, which can be frustrating for homeowners. Smoke alarms that ionize are best utilized in areas with no cooking appliances, like bedrooms and hallways.

Photoelectric Smoke Alarms

Smoke alarms using photoelectric technology use the use of light beams that detects smoke. If smoke gets into the alarm it scatters the lightand causes the alarm to sound. These types of smoke alarms are good at finding slow, smoldering fires and are less vulnerable to false alarms from cooking or steam.

However, photoelectric smoke alarms are not as effective in detecting rapid flames. They’re also typically more expensive than ionization-based smoke alarms. Photoelectric smoke alarms should be employed in areas that have cooking appliances, for example, living rooms and kitchens.

Dual Smoke Alarms with Smoke Sensors

Smoke alarms with dual sensors incorporate photoelectric and ionization sensors to offer the most comprehensive fire detection. They are effective in detecting both quick, flaming flames and slow burning fires and are less prone to false alarms than photoelectric or ionization smoke alarms by themselves.

However dual sensor smoke alarms tend to be more expensive than photoelectric or ionization smoke alarms alone. Dual sensor smoke alarms should be employed when both quick burning fires, flames and slow, smoldering fires are possible for example, living rooms and bedrooms.

Smart Smoke Alarms

Smart smoke alarms connect to your home’s Wi-Fi networks and will send out alerts to your smartphone or other device if they spot smoke or fire. They are also able to be connected into other home smart devices such as smart thermostats or security systems.

Smoke alarms with smart technology are effective at providing real-time alerts even when you’re not home. However, they are generally higher priced than conventional smoke alarms, and require an active Wi-Fi connection in order to function correctly.
