The modern hardwired First Alert SC9120B Hardwired Combination Smoke and Carbon Monoxide Alarm has a battery backup and is hardwired. In the event of a power outage, the hardwired detector has a 9-volt battery backup for ongoing operation.
The alarm can be connected to other compatible BRK, and First Alert hardwired smoke and carbon monoxide detectors by easy-adapter connectors, removing the need to rewire. Connect to Other Alarms for Better Protection: One or more compatible BRK or First Alert CO/smoke detectors in a single-family home can be connected to this hardwired detector.
In our guide, you can learn more about are all smoke detectors compatible. By the end, you’ll know more about can I mix hardwired smoke detectors, or do hardwired smoke detectors have to be the same brand? (Learn How To Turn Off Doorbell Breaker)
Are Smoke Detector Connectors universal?
Some smoke and CO detectors come with adaptor adapters that allow them to connect to compatible BRK and First Alert hardwired smoke detectors.
Can you, for example, use a Kidde to First Alert adapter to mix and match old smoke detectors with newer models?
In general, using the same make and model for all equipment meant to be compatible will ensure that they work together.
Other devices, such as smoke and carbon monoxide alarms, may or may not function together, so don’t mix them!
Many people wonder if Kidde to First Alert smoke detectors is reliable.
The First Alert BRK ADK-12 Smoke Alarm Adapter Plug connects to Kidde, Fyrnetics, and Lifesaver alarms without rewiring.
Can one smoke detector set off another, you might wonder?
Smoke detectors that run on batteries are stand-alone devices. However, if you have AC-powered smoke detectors in your home and it was built within the previous ten years in the United States, they are almost certainly hooked together to communicate.
This type of wiring ensures that all the other alarms sound if one alarm goes off, as this is how interconnected alarms should work.
If no alert sounds when you use the test feature on any interconnected alarms, check the fuse or circuit breaker giving power to the alarm circuit.
According to the National Fire Protection Association, you should replace your smoke detector when it reaches the age of ten years. By doing this, your hard-wired smoke detectors should remain compatible. (Read Smoke Detector Circuit Breaker Guide)
Do All Smoke Alarms Fit The Same?
A common question is whether I can mix and match my hardwired First Alert alarms. Models from First Alert, BRK, and Onelink that are hardwired can be mixed and matched.
The wiring harness and connector are the same on all current models.
It’s not good to mix brands because many companies can only guarantee that First Alert and BRK alarms will work together.
If you are in need of replacing Firex smoke detectors, be sure they’re compatible before replacing Firex smoke alarm to another brand like Fyrnetics.
Each model and brand have its own set of criteria, which will differ from house to house.
For example, a photoelectric device in the kitchen or bathroom, a strobe alarm in the bedroom, a heat detector in the garage, ionization detectors in the basement, and combined smoke and CO alarms in the hallways are all possibilities.
Combination alarms can get around this placement issue, yet they still have to be compatible with each other.
Is it safe to replace hard-wired smoke alarms with smoke and CO detectors? This is a common question among homeowners.
A smoke/CO detector can be used in place of a smoke detector. All current First Alert and BRK alarms have the same cable harness and connector.
Are First Alert and Kidde The Same?
First Alert offers superior characteristics than the Kidde because of the alarm system with a verbal warning of the threat.
Can multiple brands of smoke detectors be interconnected? For example, Onelink and BRK models are fully interchangeable with a hard-wired smoke alarm from First Alert.
The wire harness and connector are the same, although there isn’t any recommendation for mixing other brands outside of First Alert and BRK alarms.
Unfortunately, not all smoke alarms are created equal. However, you can find two sensors for detecting fire and smoke, which explains this.
Those two sensors are in a photoelectric smoke alarm versus “ionization” sensors. Both monitor for different sorts of smoke and fire heat detector.
Kidde Smoke Alarms are a huge name, and many ask, do all Kidde none hard-wired alarms fit the same mount as others.
These none hardwired smoke alarms feature one-screw mounting brackets to make installation easy.
Once you activate them, the battery-powered smoke detectors last for ten years, which is the life of the alarm.
You may often hear the term Wireless Interconnect? All this was the older models of Wireless Interconnect alarm were called ONELINK. Onelink now refers to the range of smart lifesaver alarms for the home. (Read Will Unplugging A Smoke Detector Set It Off)
Can You Interconnect Different Brands Of Smoke Detectors?
You may wonder, is Wireless Interconnect the sole choice for linking alarms together, or can assorted brands of smoke detectors be interconnected?
Rather, First Alert alarms include a variety of technologies that allow alarms to communicate with one another.
First Alert alarms Wireless Interconnect smoke alarms function on a “mesh network” to combine smoke alarms for greater safety and response in an emergency.
First Alert Wireless Interconnect alarms transmit, receive, and resend the signal sent to them by the initiating alarm’s signal.
Suppose the master bedroom alarm cannot receive the signal because it is too far away or because of an impediment inside the house.
The mesh network of First Alert Wireless Interconnect alarms re-routes and resends the signal via the other alarms, increasing the likelihood that all alarms will receive the signal.
It is more reliable integrate smoke alarms on a “mesh network” to reliably interconnect smoke detectors wirelessly, and thus get a smoke alarm sound from a smoke detector near to you around the home.
How many First Alert Wireless Interconnect alarms can I integrate into my system?
The First Alert Wireless Interconnect is a smoke and carbon monoxide alarm system that is fully integrated.
The NFPA states up to 18 units of either RF (wireless communication) or hard-wired can be networked. In this configuration, you can have a maximum of 12 smoke alarms and balance carbon monoxide alarms.
On a system of this nature, you may ask how these First Alert Wireless Interconnect smoke alarms connect?
The First Alert Wireless Interconnect integrated smoke alarm system instantly links through the software using 65,000 security code permutations.
You’ll discover it eliminates any need for manual dip switch programming, saving time and confusion during installation.
How to program and link First Alert Wireless Interconnect Smoke Detectors?
Follow the Wireless Interconnect Pairing Instructions in the operators manual to program the alarms to communicate with one another before installing them.
Photoelectric smoke sensors are used in the First Alert Wireless Interconnect system. In addition, kitchens and bathrooms, which are typically more prone to nuisance alarms from cooking smoke and steam from showers, benefit from photoelectric sensor technology.
Some parts of the country require photoelectric alarms in high-nuisance locations such as kitchens and bathrooms. Photoelectric smoke sensor technology is more resistant to nuisance alarms.
Is it possible to silence a First Alert Wireless Interconnect smoke or carbon monoxide alarm?
There are two options for silence in all First Alert Wireless Interconnect alarms: For several minutes, Alarm Silence can quiet nuisance alarms.
When the low battery chirp wakes you up in the middle of the night, switch it off and replace the batteries when it’s more convenient.
What batteries do First Alert Wireless Interconnect alarms use?
Two “AA” batteries are required for each First Alert, BRK Wireless Interconnect alert.
This includes smoke alarms that are battery-operated and hardwired units and CO alarms, and combination smoke and CO alarms with battery backup and a full wiring harness to power them.
Is there a warranty with First Alert Wireless Interconnect systems?
The combined smoke and carbon monoxide alarms have a 5-year limited warranty, whereas all First Alert Wireless Interconnect smoke alarms that are battery-operated alarms have a 10-year limited warranty. (Read Water Leaking From Ceiling Through Smoke Detector)
Are all the First Alert Wireless Interconnect products wireless?
The First Alert Wireless Interconnect range includes only wireless equipment. You will, however, be able to hardwire your alarms into your property’s electrical system.
You can use the smoke alarm adapter plug to help connect Kidde smoke alarms and other compatible devices.
