Introduction – Kidde Vs First Alert Smoke Alarms

Fire and smoke can present some of the most dangerous emergencies in your home. A few seconds can mean the difference between life and death in a fire, which is why a properly installed smoke detector can give you a head start. Smoke and deadly gases tend to spread farther and quicker than heat. That’s one of the reasons why most fire victims die from smoke and poisonous gases inhalation rather than burns. The majority of fatal fires happen when families are asleep because occupants are unaware of the fire until there is not adequate time to escape. A smoke detector keeps watching around the clock, sounding a piercing warning when it detects smoke. This often allows a family the precious, but the limited time needed to escape. Properly installed and maintained smoke detectors are considered to be one of the best and least expensive means of providing an early warning of a potentially deadly fire and could reduce the risk of dying from a fire in your home. 

Smoke detectors don’t seem to get the same attention as home security systems, which can be an expensive mistake for something so crucial to home and personal safety. Smoke detectors are a crucial element of home safety since they automatically detect and alert you of the presence of smoke, potentially saving your life in the case of a fire. While it’s easy to forget to check and test smoke alarms on a regular basis, it’s critical to make sure they’re not just well-maintained, but also properly installed.

According to the National Fire Protection Association, having smoke alarms can reduce the chance of fatality in a residential fire by 55 percent. The smoke detector siren will sound at any time of day or night to alert you to the presence of a potential fire, allowing you to quickly check the nature of the problem and hopefully avoid any damage. When installed correctly, the smoke detector can also assist firefighters in quickly locating the fire in the home, allowing them to focus their efforts more effectively. To make your decision easier, we at cleaning King are comparing Kidde versus first alert smoke detectors.

Kidde smoke detector functions as a single unit smoke alarm and features Hush, allowing you to quickly silence annoying alarms. The PI9010 is easy to install, no wiring is required. This smoke alarm combines both photoelectric and ionization sensors. Ionization sensing alarms may detect invisible fire particles (associated with flaming fires) faster than photoelectric alarms. Photoelectric sensing alarms may detect visible particles (associated with smoldering fires) sooner than ionization alarms. Kidde highly advises that both ionization and photoelectric smoke alarms be installed to help ensure optimal detection of the various types of fire that can occur within the home.

The Kidde PI9010, 9V battery-powered smoke alarms provide continuous protection against smoke and fire hazards even during power outages. The PI9010 also includes flashing LEDs to indicate that the alarm is functioning properly, a low battery warning, and a loud 85dB alarm.

Kidde Smoke Detectors


First Alert has been protecting homes and families since 1958. It is designed to help promote household safety; the First Alert 9120B Hardwired smoke detector can provide an important early warning of fire. This hardwired smoke detector uses an ionization smoke sensor to reliably detect smoke from hot, fast-flaming fires. This unit detects CO as well as smoke, so you don’t need to purchase additional units for carbon monoxide detection. In addition, you can network up to six (6) Kidde smoke detectors, which should be enough in most single-family homes. This First Alert model has the added benefit of allowing you to set voice location on each connected smoke detector so that when the alarm sounds across the networked devices, it can tell you the location of the device that initiated the alarm.

Stand-out features include

  • Ionization Sensor Reliably Detects Flaming Fires: It comes equipped with an ionization sensor to provide the earliest possible warning of a fast-flaming fire. The sensor is optimized to detect flaming fires, such as those caused by kitchen grease, paper, and other fast-combusting materials.
  • Battery Backup for Detection during a Power Outage: This smoke detector is designed for hardwired installation, but it also features a battery backup that helps ensure continued functionality in the event of a power outage. The smoke and fire detector comes with a 9-volt battery and features a pivoting, easy-to-access battery drawer that allows you to replace the battery without dismounting the hardwired alarm.
  • Hassel-Free Easy Installation: This smoke detector features a streamlined mounting system with a gasket-less base to facilitate hassle-free installation. The mounting bracket keeps the detector secure over a wide rotation range while maintaining perfect alignment. The ionization fire alarm also comes with a dust cover to keep the unit clean during construction. 
  • Works in Tandem with Other First Alert Alarms: In addition to functioning independently, this hardwired ionization smoke alarm can also integrate with up to twelve (12) other First Alert or BRK hardwired alarms for coverage of larger spaces. This detector also integrates with up to six other compatible devices, such as bells, horns, and repeaters. If one alarm in the series is triggered, it will all sound. The fire alarm features a latching indicator to identify which unit triggered the alarm, alerting you to the area of danger.

Conclusion – Kidde Vs First Alert Smoke Alarms

The Kidde device excels at connectivity. It offers connectivity up to 24 total devices; Twelve (12) Kidde devices and twelve (12) other devices, although most household applications require 6 to 8 other devices. 

The First Alert smoke detector does not only detects smoke, this smoke detector also detects unsafe levels of carbon monoxide (CO) in your home. There are lights on the front of the smoke detector to let you know if there is a fire or CO emergency.

Among other amazing features, what makes the First Alert smoke detector stand out is the voice location feature. It’s better than the Kidde smoke detector because of the alarm system with a verbal warning of the threat, which allows you to know where in your house the alarm was initiated without needing to refer to a smartphone app. This feature actually brings the First Alert smoke detector into the realm of functionality you get with a smart device. 

Both smoke detector models offer great features, however, we at Cleaning King highly recommend the First Alert Smoke detector.

FAQ's - Kidde Vs First Alert Smoke Alarms

What do Kidde smoke detectors detect?

Carbon monoxide and fire can make for a deadly duo, but Kidde makes it much easier to protect yourself against both. Combination smoke and carbon monoxide alarms have sensing technologies that work together to detect fires and the colorless, odorless, tasteless gas known as CO – the silent killer.

Why does Kidde’s smoke detector blink red?

If the smoke is not too dense, the alarm will be silenced immediately and the red LED blinks every 10 seconds. This indicates that the alarm is in a temporarily desensitized condition.

What does a solid green light on a Kidde smoke detector mean?

In most smoke detectors, the green LED is used to indicate the power status. If my smoke detector (Kidde brand) flashes green, it means there are few or no batteries installed. Solid green means AC power is connected. Flashes green every sixty seconds when the power is disconnected and runs on batteries.

How long do First Alert smoke detectors last?

The smoke detector should be replaced Ten years from the date of manufacture. Combo smoke/CO alarms should be replaced after five to seven years (depending on the model). Put the alarm back on the ceiling or wall if it is less than ten years old. Replace alarm(s) older than ten years with new units.

Is First Alert the same as BRK?

The same parent company (Newell Brands) owns First Alert and BRK. First Alert is the retail division, and BRK is the commercial division. Note: Some retailers sell BRK products under the First Alert brand.

Does the First Alert smoke alarm detect carbon monoxide?

The First Alert combination smoke and carbon monoxide Alarm feature dual sensors to detect both smoke and carbon monoxide in a single device. A photoelectric sensor detects the smoke most often produced by smoldering fires and minimizes false alarms from shower steam or cooking smoke.
