Dual Sensor Smoke Alarms

Dual sensor smoke alarms combine photoelectric and ionization sensors to offer the most complete fire detection. They are good at detecting both rapid, flaming fires as well as slow, smoldering fires, and are less vulnerable to false alarms than either ionization or photoelectric smoke alarms by themselves.

However dual sensor smoke alarms tend to be more expensive than ionization or photoelectric smoke alarms by themselves. Dual sensors are best utilized for areas in which both rapid burning fires, flames and slow, smoldering fires can be a possibility, such as bedrooms and living spaces.

Smart Smoke Alarms

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