5 Best Smoke And Heat Detectors for 2021

1. Honeywell 5808W3 – Wireless Smoke/Heat Detector

I will be starting with one of the best-selling smoker and heat detector, the Honeywell 5808W3. It’s a wireless photoelectric smoke/heat detector that has been trusted by many of its users.Honeywell 5808W3 – Wireless SmokeHeat Detector

The Honeywell built-in transmitter is designed to work with any 5800 series wireless receiver/transceiver for the residential installations, but for the commercial installations, you will need the 5883H or 5881ENHC receiver.

The best part about this smoke /heat detector is that its transmitter sends alarm, tamper, battery condition and maintenance messages to the system receiver.

The heat detection system in this model uses a restorable, built-in temperature thermal detector (above 135 degrees Fahrenheit) which is capable of sensing pre-freeze condition also when the temperature goes below 41 degrees Fahrenheit.


  • Enhanced Robust RF Field Strength
  • Additional LED Status Indicators
  • Smart signal Check
  • Easy installation
  • UL Approved


  • Price is a bit high

2. Visonic MCT-427 – Smoke & Heat (Wireless Detector

Visonic MCT-427 – Smoke & Heat (Wireless DetectorThe second in this best smoke and heat detectors review is the Visonic MCT-427 wireless smoke and heat detector. It’s a fully supervised wireless detecting system compatible with the Visonic PowerCode wireless receivers and Visonic PowerMax home security systems.

The first thing I noticed about this smoke/detector is the streamlined design which allows it to fit almost all residential and commercial application.

Additionally, you will love to hear that its battery life is quite exceptional, around eight years, cutting the maintenance cost. It works its magic when it senses any smoke or when the temperature goes above 122°F and activates the alarm immediately.


  • Simple wall or ceiling installation
  • Internal sensitivity test button
  • Modern, streamlined design
  • Easy battery replacement
  • EN and UL fully certified
  • 3V lithium battery


  • Expensive

3. Firewolf FW4-H – Smoke & Heat Detector

Firewolf FW4-H - Smoke & Heat DetectorThe next product in this list is the Firewolf advanced photoelectric smoke and heat detector. According to customer reviews, this detector detects all types of fire including wood, paper, gasoline, smoldering fires, polystyrene, etc.

which is an advancement for superior performance to its previous photoelectric detectors. The attractive, low profile, the baseless design allows to be used for residential and commercial application without interfering with the design.

Furthermore, the detector uses dual LEDs for 360-degree coverage. I love the patented innovative chamber design which reduces unwanted reflections and ensure the light source is extremely focused and pure. I wouldn’t forget to mention that it features a built-in thermal heat sensor which detects a wide range of fires ideally from 135 degrees F.


  • Accurate built-in thermal heat sensor
  • Improved photoelectric beam design
  • Superior chamber design
  • Precision detection


  • Pricing isn’t impressive

4. Interlogix 541NCSXT – photo/heat 4w temp sounder

Interlogix 541NCSXT – photoheat 4w temp sounderMy next best smoker and heat detector might not be the best selling, but it’s the best cheapest in my review. The Interlogix 541NCSXT 4w is what I’m talking about.

The best part I love about this smoker/heat detector is the fact that it comes with a sounder and that it integrates reliable, self-diagnostic smoke/heat detection into a security system. It doesn’t end there, and this detector features drift compensation which enhances performance and while also reducing false alarms.

The detector drift adjusts the detector’s sensitivity when it gets dirty with time. However, not everything is likable about it. It’s isn’t a standalone system as it requires to be connected to an alarm panel.


  • Built-in rate-of-rise heat detector
  • Streamline, low profile design
  • Connects to an alarm panel
  • Drift compensation
  • Built-in 85dB alarm


  • Requires wiring

5. Edwards SIGA-PHD– Multi-Sensor Smoke/Heat Detector

Edwards SIGA-PHD- Multi-Sensor SmokeHeat DetectorEdwards SIGA-PHD multi-sensor smoker/heat detector is my last product. When I was preparing this best smoke and heat detectors list, I came across this detector that caught my attention.

The first thing that impressed me is the fact that it employs environmental compensation which lowers the maintenance costs. It also features a continuous self-diagnostics which makes sure there is reliability over the long-haul, which I would say is very impressive.

Additionally, the SIGA-PHD detector collects analog information from its sensory system and converters the data into digital signals. Its intelligent onboard microprocessor measures and analyzes readings from the smoke and heat sensor and compared them to historical data which is then passed through digital filters.

The filters remove signal patterns that aren’t typical of fire which in turn eliminates unwanted alarms.


  • Smart onboard microprocessor
  • Continuous self-diagnostics
  • Minimal maintenance costs
  • Intelligent digital filters
  • 12 Month Warranty
  • 30 Day Return


  • Hard to find its accessories

Best Smoke And Heat Detectors [Buyer’s Guide]

It’s time now you know how to choose the best smoke and heat detector. After reading the best smoke and heat detectors reviews above, one thing is clear. Each smoke/heat detector in the list has some unique features which make it hard to pick the best. So, I have prepared this guide to help you do that. It contains some of the features that you need to consider to make sure you make a perfect choice.


Smoke and heat detectors can be wireless or hardwired to your home electrical system. Mostly the hardwired will need professional installation. The wireless comes with one advantage, and you can install it in an already finished home. However, they do depend on batteries which require changing some time to time. If you decide to go with hardwired, you need to ensure there are backup batteries for the outages cases.

Smoke sensor type

Smoke and heat detectors use two types of smoke sensors to alarm you when there is smoke in the house. The photoelectric sensors are the best at detecting smoldering fires. On the other hand, ionization sensors are better are excellent at detecting sudden, rapid-burning fires. From an expert point of view, photoelectric detectors are exceptional as they do not cause as many false alarms, but for your ultimate safety, It’s recommended you go with an indicator that combines both sensors.

Thermal detector

How accurate are the thermal sensors? You need to pick a smoke and heat detector that can detect any temperature anomalies. It should be able to differentiate that change with area temperature and the heat. That way it will be able to reduce false alarms.


Because of the technology used in smoke and heat detectors, they have a life span of around seven years. No matter the type of smoke and heat detector you buy, you need therefore anticipate requiring to replace it in around seven years. Go for one that comes with a warranty to reduce the chances of having to buy a new smoke and heat detector again shortly.
