What is a photoelectric smoke alarm?

A photoelectric smoke alarm is a device that uses light to detect the presence of smoke. These alarms work by detecting the level of light in the room and triggering a notice when it reaches a certain level. As opposed to traditional smoke alarms that use carbon monoxide (CO) sensors to detect the smell of smoke, photoelectric alarms use light to see the source of the fire.

These alarms are more accurate, especially at detecting low-light levels, such as in your closet or under a bed. Additionally, these alarms have a longer battery life than CO alarms. However, they are more expensive and may not be suitable for all situations.

How does a photoelectric alarm work?

A photoelectric alarm is triggered when the light from the sensor is breached. This light level breach can be caused by smoke, fire, CO, and other sources. The light sensor is usually located in the doorbell or the indoor/outdoor light switch. When the alarm is tripped, a small amount of detecting Smoke Alarms smoke will reach the sensors and cause the alarm to sound. Photoelectric alarms use a small amount of electricity to power the sensor and the terror.

What are the different types of smoke alarms?

There are many types of smoke alarms. Here are some of the most common:

Type 1: The traditional smoke alarm. It uses a carbon monoxide (CO) sensor to detect the smell of smoke.

Type 2: A photoelectric smoke alarm that uses light to detect the presence of smoke.

Type 3: A smoke and CO detector in one. They work by sensing the levels of smoke and CO in the air and triggering an alarm when it rises above a certain threshold or is present in the vicinity of the device.

10 Best Photoelectric Smoke Alarms 2022

We’ve compiled a list after analyzing and reviewing the best photoelectric smoke alarms. We’ve also included reviews of each model so you can get a complete insight into how they function and look and what kind of carbon monoxide alarms they are ideal for. So without further ado, let’s look at the best photoelectric smoke alarms of 2022! 

Ring Alarm Smoke and CO Listener

Ring Alarm is a product that provides home security for your family. It is inexpensive compared to traditional systems but has severe bells and whistles. If you are looking for a new way to protect your home, then the Ring Alarm Smoke and CO Listener would be a good fit.

The Ring Alarm Smoke and CO Listener will alert you when there has been activity in the area, turning on lights and playing sound alarms if needed. This adds another level of safety outside of just relying on smoke detectors alone which isn’t as reliable or cost-effective as this device. There are four different sensors inside the ring so it can alert you whenever there is a fire, carbon monoxide, heat wave, or smoke.

This alarm system notifies the user when there has been activity in an area where there are devices called smoke and carbon monoxide detectors. These detectors are great for detecting fires or CO leaks in your home, but if you’re away from the house and don’t have a notification system, you can’t tell when there has been a carbon monoxide leak or a fire. With this device, you can say goodbye to false alarms.

  • Aside from alerting users to the presence of smoke and carbon monoxide gases in the home, it also comes with some other benefits that are pretty much unheard of with traditional systems, such as:
  • Alerts will automatically be sent to smartphones, even if turned off or too far away.
  • Allows users to change the sensitivity of their sensors and see the changes immediately.
  • An utterly automatic system, so no batteries are needed to run it.
  • Includes a complete home security system with customizable alerts, monitoring, and repair services. Home security is free with the Ring Alarm Security Kit (available in-store only), but this is a $199 value for an additional component with three years of monitoring. This piece is also not included with the Ring Alarm Smoke and CO Listener kit.
  • Although the Ring Alarm Smoke and CO Listener is great at keeping the home safe, it still has some shortcomings that users must address. First, however, it is essential to understand what the system will not do for them:
  • Doesn’t replace other detectors or prevent carbon monoxide from leaking from or into the home. For this reason, you must always install a carbon monoxide and smoke detector. This coverage can be achieved with: The First Alert Z-Wave Smoke + Burn Hardwired Carbon Monoxide Alarm. This alarm is also Z-Wave compatible and will be able to communicate with the Ring Alarm system.
  • The sensors all need to be hardwired into the home. If hardwiring is not an option, then you can have it installed into your garage through the “In Wall Units,” or if you have a wall between the inside of your home and your garage, then consider using this. However, if you don’t have these options, it will not work for you and is therefore not worth purchasing.

In addition, it can send emails (through Twilio) or texts if any sensors are triggered or when someone leaves the phone behind (e.g., during vacation). They have a customer service center that is available 24/7.

This device gives users an affordable way to keep their homes safe with technology never seen before in this niche. It is an excellent upgrade if you already use Ring’s Video Doorbells or Security Cameras, as they will work together. Still, they are also two different products, so they aren’t necessary if you only want to secure your home and your family. The setup is easy, but the sensors and wire are resistant to intruders, and that’s what this device is all about.

What to Look for in Photoelectric Smoke Alarms:

Many types of smoke alarms exist, but a photoelectric one is the best option for anyone who wants greater peace of mind. You can find these alarms in both wired and wireless versions, and they have three main features: power, sensor type, and lifespan. A photoelectric smoke alarm will detect the fire from the particle emitted from the toxic gas.

To make an informed decision on which one to purchase, this buying guide has highlighted 6 key points you should keep in mind before making a purchase. It includes information about power sources, sensor type and lifespan, multifunctional capabilities and smart features with backup power.

Power: Battery-powered alarms are generally more expensive than wired ones. The most expensive battery-operated smoke detector model costs more than $100, and the least expensive costs less than $20. If you have an older home with an existing smoke alarm and wish to upgrade to a photoelectric one, you can save by purchasing a brand new alarm system instead of an individual smoke alarm unit. Also, look for the newest model tested by a third-party lab or conducts its tests using its internal standards, as those models tend to be reliable.

Sensor type: The sensitivity of the photoelectric alarms varies from model to model. The sensitivity is a good feature because it can determine how quickly the smoke alarm will respond when there is a fire in your home, thus preventing unnecessary inconvenience. Look for an alarm with a sensitivity of at least 50 to 60 decibels. A lower number means the smoke detector is more sensitive, whereas a higher number means it will take more smoke particles to trigger the alarm.

Lifespan: Make sure you know the photoelectric alarms’ lifespan before making a purchase and installing it in your home. The lifespan depends on each model, but typically they last from five to 10 years depending on exposure to heat, humidity and other environmental factors and use. In general, it is a good idea to replace your photoelectric alarms more frequently than you replace your traditional smoke alarms.

Multi-functional: When replacing a smoke alarm, remove the old one and ensure that all the wires are connected and connected correctly, removing any loose connections. Then turn off all power at the circuit breaker in your home, test it, and reattach everything. After this, make sure you test the new one by pressing the test button on the back. Then you should adjust it to your preferences, if necessary.

Smart Feature: If you want to use your photoelectric alarms with a home security system such as Nest, a motion detector and camera, or any other type of interconnected system, make sure that the alarm has at least one smart feature. A good model will have the option to send a notification when the alarm is triggered or after a certain period of time. In addition, you can use it with indoor and outdoor systems.

When buying these batteries-operated alarms, you should remember that they may be affected by power fluctuations or voltage changes. To prevent this from happening, remove the battery when it is not needed and reinstall it to ensure that all wires are properly connected. Also, replace the battery if it becomes low and does not respond to the test button.

You should also be aware that these alarms can be sensitive to certain gases and may not always be activated with every gas. For example, carbon monoxide detectors are more effective for detecting gases like methane, carbon dioxide, and nitrous oxide, which are emitted from automobile exhausts.

Backup power: Smoke alarm types are usually classified into two categories: ionization-based alarms that use a chemical reaction to emit a glow (or a spark) when they detect smoke, and photoelectric smoke alarms that use light instead of an electrical current to detect smoke particles. The key difference between these two types is energy consumption. Ionization-based alarms are more energy-intensive, emitting a glow that consumes more electricity. On the other hand, the photoelectric type uses less energy and is less sensitive to fluctuations or voltage changes.

To make an informed decision, it is important to know first which type of smoke alarm you want to install in your home. The main difference between these alarms is their cost and lifespan, but they will also have different features you can use to decide which one you should buy. For example, ionization-based alarms do not depend on electricity and must be replaced after 10 years when the internal batteries run out of power.


Choosing a high-quality smoke detector is the right way to protect your family and home. It is the most important thing you can do to ensure home and family safety. People often think that alarms don’t work, but they do! Don’t think they won’t be able to save your life or someone else’s. They have been saving lives for decades and will continue for years to come. Always choose the right product, carefully read about it, and you will be fine.
