What to look for in a smoke detector?

Carbon monoxide and Smoke

Your house needs to alert you about the dangers of both Smoke and carbon monoxide. Some detectors can accomplish both, so you don’t have to deploy (and manage) several devices. 

Note that, as previously said, smart batteries and smart listeners do not directly detect Smoke or CO, so you’ll need to make sure your house’s real alarms enable these sorts of detection.

Detector sensitivity and accuracy

Without actually burning down your house, it isn’t easy to objectively assess how effectively a smoke/CO detector performs its primary function. 

Simulating smoky circumstances, on the other hand, can offer some information about a detector’s sensitivity. 

You may also take into account the broad agreement on the underlying technology of a smoke detector.

Various types of notifications

Although a loud siren is expected, verbal warnings are very useful: They can inform you not just what sort of threat has been identified but also where it is and how to respond (whether it’s opening a window or contacting 911).

 Another advantage is the alarm’s color-coded LEDs. And, of course, prompt push alerts to your phone are a necessity.

Multiple users are allowed

Obviously, you’re safer if more than one person receives a push notification that the house is on fire. So look for a system that uses an invitation system to accommodate numerous users.


Some gadgets have the ability to communicate with one another, so if one alarm goes out, all of the other alarms in the house will go off as well. 

If you have a large house and are concerned that you might not hear an alarm going off elsewhere, this can be a huge help. 

Because we only tested single alarms in our evaluation, we didn’t test interconnectivity features, so verify the specifications.

Consider if a major smart home hub supports your smoke alarm if you want to link it with the rest of your house. 

For example, the Nest Protect is clearly linked to the Nest ecosystem, but it also has Alexa, SmartThings, and HomeKit choices. It’s worth noting that we experienced mixed success with some of these hooks—and even if you do connect the alarm to your smart home hub, there’s no guarantee that it’ll work.

How Do Z-Wave Smoke and Carbon Monoxide Detectors Work?

Photoelectric sensors are used in most smoke detectors these days, which means they detect Smoke using light. 

A low-light emitting diode and a light-sensing sensor are both included in this sort of detector. 

The sensor detects that light when Smoke or other particles in the air reflect it and the alert sounds. Smoke detectors of this type are extremely quick to react.

Ionization sensors, which employ ions to detect Smoke in the air, are the other sort of detector. These detectors have a higher rate of false alarms than photoelectric detectors, although they are typically less expensive.

Carbon monoxide detectors are frequently included in the finest contemporary smart smoke detectors. 

Carbon monoxide is a poisonous gas that is odorless and almost undetectable. CO leaks are most commonly caused by a furnace, although they may happen in any house.

This odorless gas can build up in the home if there isn’t enough ventilation, causing serious sickness, if not death.

Carbon monoxide detectors use an electrochemical sensor with electrodes in a chemical solution to monitor a shift in electrical current whenever the gas comes into contact with the electrodes.

Types of Z-Wave smoke detectors

Ionization, photoelectric, and dual sensors are the most common types of sensors found in smoke alarms. The following are the key distinctions between the three.


Light is used to detect Smoke in photoelectric smoke alarms. Smoke particles floating in the air (as with a smoldering fire) disperse the light beam in the sensory chamber, triggering the alarm.


Ionization smoke detectors detect Smoke using radiation and an ionization chamber. Ionizing radiation aids in the detection of small quantities of Smoke in the air, such as that produced by a burning fire. 

When Smoke enters the sensor chamber, the ionizing radiation current is interrupted, causing the alarm to sound.

Dual sensors

Photoelectric and ionization sensors are included in dual sensors. These are thought to be the safest Smoke and fire detectors. 

Because these dual-purpose sensors detect both blazing and lesser, smoldering flames, it’s doubtful that any fire-related hazard will slip past them.

Best Z-Wave Smoke Detecto – FAQs

What is the difference between a smart smoke alarm and a traditional smoke alarm?

Smart smoke and carbon monoxide detectors, like other smart home gadgets, link to your house’s Wi-Fi and, as a result, your smartphone. 

To put it another way, they go above and beyond the standard smoke alarm. 

Smart smoke detectors are popular for this reason, but some high-end versions incorporate other “smart” functions such as voice control via Alexa, weather updates, and more.

What is a monitor?

Monitors effectively “listen” for your smoke and carbon monoxide alarm to go off, and if they do, they send you a smartphone notice. 

They’re usually put near your current smoke detectors, and they’re connected to your home Wi-Fi network. 

Some plug into an electrical outlet, while others are battery-powered. They do not, however, enable you to do so.

What does a Z-wave alarm entail?

Z-Wave is a radio-wave-based wireless technology that allows smart gadgets and appliances to interact with one another. 

The use of Z-Wave technology in a range of smoke and carbon monoxide alarms gives a number of intuitive advantages not seen in other detectors.

  • Advanced Smoke + Carbon Monoxide Detection means you’ll be notified of these two dangers via a loud (85dB) alarm as well as a mobile device notification. This provides additional security by allowing you to maximize your peace of mind when you’re away from home. (Z-Wave is compatible with the Ring Alarm Security Kit.)
  • Interconnected Alarm Feature: This feature allows you to connect numerous First Alert Z-Wave Smoke & Carbon Monoxide Sensor Alarms. Place detectors in several rooms to create a personalized security network that is tailored to your environment. When one alarm is activated, it sets off all other alarms that are connected to it. This is a fantastic feature that can improve your Smoke and CO protection.
