For users looking to add smoke and heat detectors to their wireless systems, there are always some great options to consider. Of course, the specific models you can choose from will depend which alarm panel you are using. We're here to present the best options for some popular systems.

For this list, we are presenting our favorite combination smoke and heat detector and standalone heat detector for each system. Combination smoke and heat detectors are what you should use in most locations of your home or business. During a fire, smoke is usually detected before heat, so a combination sensor will rely on smoke detection as its primary method for detecting fires. Heat detection serves as a good backup to smoke detection.

But there are some rooms of a home where it is better to use standalone heat detectors. This is because using a regular smoke detector in these rooms could result in false alarms due to excessive dust, moisture, or smoke that is normally present. Examples of rooms where a standalone heat detector is often a better option include kitchens, attics, garages, and bathrooms. Remember that standalone heat sensors are one-and-done devices, and they must be replaced after activation. Do not test them using a hair dryer!
