Thank You First Alert -Replacing my smoke alarms was a snap!

I ordered four First Alert smoke alarms to replace my Firex alarms which were installed when the house was built. The adapter plugs made the install of the First Alert alarms a snap. The hardest part of this project was moving the ladder from room to room. I ordered from the First Alert store. Items were packed securely and arrived within 4 business days. Five stars for my overall experience with First Alert.

Fits like a glove

My First Alert Smoke Alarm plugged right into my existing mount without having to use any adapter. The original alarm from First Alert was installed when my house was built in 2006 and worked great until it finally died last month. Hope the model stays active in your inventory for a long time to come.

I replaced my old Kiddie smoke alarms with First alert detectors last month. I Salesperson I spoke with was very knowledgeable regarding these detectors. Ordering was easy and the shipment came quickly. Thanks First Alert!

Smoke Detector

Purchased one these detectors a year ago to replace an old 20+ years faulty detector. Works well and it immediately sensed a smoking pan on the stove. Bought this one to replace an equally old detector upstairs.

First Alert, the #1 in Alarm Technology!

Have always used First Alert, when Installing Alarms. This order was a Replacement for Smoke Detectors that were installed when our House was built. Of course I chose First Alert to replace the originals, when you have the Best Available, why would I consider any other Detector?!

Ordered these as replacements for 11 year old units that were installed when our house was built that had gone bad. Installation could not have been easier using the adapter plugs! Did have to switch out the base attachment as well, but that too was very simple to do.

First Class

My order of 6 smoke detectors arrived quickly after I placed it and the units installed with no problems. Very satisfied.

Hardest part of changing out the 10+ year old units was opening the package. Simply unplugged the old units, added the adapter and then swapped the trim/mounting plate with 2 screws. Attached it to the ceiling... Tested it...beep...beep...success! Simple, fast, and it fits. Enough said.

Bought two of these alarms and had both installed in just a few minutes! Took longer to get the power turned off to the two locations than it did to install them. Alarm test works and hope they never get tested operationally!

What is the proper placement of smoke alarms?
It is important that you have the proper placement for your smoke alarms. Install your alarms at least 20 feet from appliances like furnaces and ovens, which produce combustion particles. Alarms should be at least 10 feet from high humidity areas like showers and laundry rooms, and at least 3 feet from heat/AC vents. Be sure to install a smoke alarm in each bedroom, one at the top of each stairwell, and one on every level.

Hardwired Ionization Smoke Alarm w/ Adapter Plugs

Enhance your household's fire safety and enjoy greater peace of mind with the First Alert SA9120BPCN Hardwired Smoke Alarm with Adapter Plugs. Equipped with an ionization sensor, this 120-volt hardwired smoke alarm reliably detects smoke from fast-flaming fires and alerts you with an 85-decibel alarm. Included adapter plugs eliminate the need for re-wiring during installation, while a backup battery helps keep the unit running in case of a power outage. Designed to maximize accessibility and ease of use, this hardwired smoke detector features a single button that allows you to test and silence the alarm. And thanks to the universal mounting bracket, this smoke alarm is easy to install.

Ionization Sensor Reliably Detects Flaming Fires

The First Alert SA9120BPCN Hardwired Smoke Alarm with Adapter Plugs comes equipped with an ultra-reliable 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 paper, kitchen grease, and other fast-combusting materials.

Adapters Included for Easy Installation

To facilitate hassle-free installation, this smoke alarm comes with adapter plugs that eliminate the need for rewiring if you are replacing an existing First Alert or BRK branded detector. The universal mounting bracket further eases installation and covers up drywall cutouts, while tamper-resistant locking pins keep the alarm secure.

Battery Backup for Detection during a Power Outage

This smoke alarm 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 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 alarm.

Works in Tandem with Other First Alert Alarms

In addition to functioning independently, this smoke alarm can also integrate with up to 12 other First Alert or BRK hardwired alarms for coverage of larger spaces. If one smoke alarm in the series is triggered, they will all sound. The alarm features a latching indicator to identify which unit triggered the alarm, alerting you to the area of danger.

The First Alert SA9120BPCN Ionization Smoke Alarm meets UL standards and features a 10 year limited warranty.
