Smoke Alarms for Ionization

Smoke alarms with Ionization use only a tiny amount of radioactive substance to ionize air in the alarm. When smoke enters in the smoke alarms, it interrupts the ionization process, causing the alarm to sound. These kinds of smoke alarms are good at detecting fast, flaming fires and generally cost less in comparison to photoelectric fire alarms.

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

Photoelectric Smoke Alarms

Smoke alarms using photoelectric technology use the use of light beams for detecting smoke. When smoke is detected in the alarm, it scatters the lightand causes the alarm to sound. Smoke alarms of this type are effective in detecting slow, smoldering fires, and are less susceptible to false alarms due to steam or cooking.

However, photoelectric smoke alarms aren’t as effective in detecting rapid burning fires. They are also generally more expensive than ionization-based smoke alarms. Smoke alarms that are photoelectric can be used in areas in which there are cooking appliances, for example, living rooms and kitchens.

Two Sensor Smoke Alarms

Smoke alarms with dual sensors blend photoelectric and ionization sensors to offer the most complete fire detection. They are good at detecting both quick, flaming flames and slow, smoldering fires, and are less vulnerable to false alarms than photoelectric or ionization smoke alarms by themselves.

However, smoke detectors with dual sensors are generally more expensive than either ionization or photoelectric smoke alarms by themselves. Dual sensor smoke alarms should be used when both fast, flaming fires and slow burning fires are possible, such as 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 phone or any other device when they detect fire or smoke. They can also be integrated to other intelligent home devices, for example, smart thermostats or security systems.

The smart smoke alarms can be good in providing instant alerts even when you’re not home. They are, however, generally more expensive than traditional smoke alarms and require an active Wi-Fi connection in order to work properly.
