Smoke Alarms for Ionization

Ionization smoke alarms use only a tiny amount of radioactive material to ionize the air inside the alarm. If smoke gets into in the smoke alarms, it interrupts the process of ionization, which causes that the alarm alarm to go off. These types of smoke alarms are excellent at detecting quick flames, and they generally cost less than photoelectric smoke alarms.

However, ionization smoke alarms are not as effective at detect slow burning fires. They are also more vulnerable to false alarms from steam or cooking and can cause a lot of frustration for homeowners. Ionization smoke alarms should be employed in areas where there are none of the cooking equipment, for example, hallways and bedrooms.

Photoelectric Smoke Alarms

Smoke alarms using photoelectric technology use a beam of light that detects smoke. When smoke enters the alarm and scatters the lightand causes the alarm to sound. These kinds of smoke alarms are good at finding slow, smoldering fires and are less vulnerable to false alarms due to steam or cooking.

But smoke alarms that use photoelectric technology aren’t as effective at detecting quick, flaming fires. They are also generally more expensive than ionization alarms. Photoelectric smoke alarms should be utilized in places in which there are cooking appliances, like kitchens and living spaces.

Dual Sensor Smoke Alarms

Dual-sensor smoke alarms blend both ionization and photoelectric sensors to provide the most complete fire detection. They are effective in detecting both rapid, flaming fires as well as slow, smoldering fires, and are less prone to false alarms than either ionization or photoelectric smoke alarms alone.

However, Dual sensor smoke alarms are typically more expensive than ionization or photoelectric smoke alarms by themselves. Dual sensor smoke alarms are best utilized for areas in which both rapid flames, flaming fires as well as slow, smoldering fires are possible, such as bedrooms and living rooms.

Smart Smoke Alarms

Smart smoke alarms are connected to your home’s Wi-Fi networks and will send out alerts to your phone or other devices if they spot smoke or fire. They also can be integrated to other intelligent home devices, for example, smart thermostats and security alarms.
