Summary of the Article: Interconnected Smoke Alarms
When smoke and carbon monoxide (CO) alarms are interconnected, each alarm can now tell you when there’s smoke or carbon monoxide in any room that has a smoke/CO alarm. A traditional alarm can alert you to the presence of smoke, fire, or carbon monoxide, but it can only detect the area around it.
Interconnected smoke alarms provide the best protection as when one alarm sounds, they all sound. Interconnection can be done using hard-wiring or wireless technology. It is important that all interconnected smoke alarms are from the same manufacturer.
To check if smoke detectors are interconnected, most alarms have a test push button. By pressing this button for approximately 5 seconds, the alarm should sound. If the detectors at the property are interlinked, they will also sound.
Hardwired smoke detectors with battery backups, such as BRK or KID, are often used for interconnecting wired smoke detectors. These detectors have a 9-volt backup battery and can be hard-wired to ensure interconnection.
There is no electrical code requirement for hardwired smoke detectors to be connected to a dedicated circuit, but it is recommended to install a new circuit for this purpose. In most cases, hardwired smoke detectors are connected to a general lighting circuit or outlet circuit.
The NFPA states that up to 18 total units can be interconnected (RF or hardwired) with a maximum of 12 being smoke alarms and the remaining being carbon monoxide alarms.
Hardwired smart detectors can interconnect with other hardwired units in your home through the “interconnect” wire on the back of the alarms. Examples of such smart detectors include 1042135 and 1039102.
Interconnected smoke alarms will not work if one is disconnected. Each detector works independently, and the battery serves as a backup in case of power loss. In the event of a fire, all detectors need to be properly functioning for optimal safety.

For the best protection, interconnect all smoke alarms. When one smoke alarm sounds, they all sound. Interconnection can be done using hard-wiring or wireless technology. It is important that all interconnected smoke alarms are from the same manufacturer.
One option is to use hardwired smoke detectors with battery backups, such as those from BRK or KID. These detectors have a 9-volt battery backup and can be hard-wired for interconnection.
The electrical code does not require hardwired smoke detectors to be connected to a dedicated circuit, but it is recommended to install a new circuit for this purpose. In most cases, hardwired smoke detectors are connected to a general lighting circuit or outlet circuit.
According to the NFPA, up to 18 total units can be interconnected (RF or hardwired) with a maximum of 12 being smoke alarms and the remaining being carbon monoxide alarms.
Yes, hardwired smart detectors like 1042135 and 1039102 can link with other hardwired units in your home via the orange “interconnect” wire on the back of the alarms.
No, the detectors work independently of each other. The battery serves as a backup in case of power loss so that they will still work as intended in the event of a fire. If you unplug one of these detectors, it will not affect the interconnection of the others.
What is interconnect smoke alarm
When smoke and carbon monoxide (CO) alarms are interconnected, each alarm can now tell you when there's smoke or carbon monoxide in any room that has a smoke/CO alarm. A traditional alarm can alert you to the presence of smoke, fire or carbon monoxide, but it can only detect the area around it.
How do you know if your smoke detectors are interconnected
Most alarms have a test push button as standard. Press this test button for approximately 5 seconds and the alarm should sound. If the detectors at the property are interlinked, they too will also sound.
Do my smoke alarms need to be interconnected
For the best protection, interconnect all smoke alarms. When one smoke alarm sounds they all sound. Interconnection can be done using hard-wiring or wireless technology. When interconnected smoke alarms are installed, it is important that all of the alarms are from the same manufacturer.
How do you interconnect wired smoke detectors
Now one of the products that we use is either a brk or a kid. They're a hardwired smoke detector with battery backups so they have a 9 volt battery in them and they also hard wire so i'd like to point
Do hardwired smoke detectors need to be interconnected
The electrical code does not require that hardwired smoke detectors need to be connected to a dedicated circuit, though there is nothing wrong with installing a new circuit for this purpose. More often, though, hardwired smoke detectors are installed by splicing into a general lighting circuit or outlet circuit.
How many smoke detectors can be interconnected
12
As with hardwired units, the NFPA states that up to 18 total units can be interconnected (RF or hardwired) with a maximum of 12 of those being smoke alarms and the balance carbon monoxide alarms.
Do hardwired smoke detectors interconnect
Yes. Hardwired smart detectors like 1042135 and 1039102 can link with other hardwired units in your home via the orange “interconnect” wire on the back of the alarms.
Will interconnected smoke alarms work if one is disconnected
No the detectors work independently of each other – the battery is a back up in case of power loss so that they will still work as intended in the event of a fire. If you unplug one of these it will still work but only as a single unit not make the rest sound their alarms.
What does interconnect wire mean
An interconnect cable connector is any connector that is attached to the end of an electrical cable with the purpose of terminating the wires within the cable and enabling the cable to connect with another product.
Do interconnected smoke alarms need to be hardwired
Interconnected smoke alarms are either hard-wired or wirelessly interconnected and powered by a ten-year lithium battery. Hard-wired smoke alarms must only be installed by a professional electrician.
Can wired and wireless smoke detectors work together
Hardwired and wireless interconnected smoke alarms
FireAngel has mixed system capability, allowing for the interlinking of battery and mains alarms. Just one mains powered Smart RF enabled alarm is required to adapt an established hardwired interconnected system to communicate to other FireAngel wireless products.
How do wireless interconnected smoke detectors work
Wireless smoke alarms communicate via radio frequency.
Each wireless alarm has dip switches on the back of the unit. When all switches are on the same setting, all smoke alarms will sound when the Test/Reset button is pushed.
How many smoke alarms can you interconnect
12
As with hardwired units, the NFPA states that up to 18 total units can be interconnected (RF or hardwired) with a maximum of 12 of those being smoke alarms and the balance carbon monoxide alarms.
Can you disconnect one interconnected smoke alarm
Most people ask themselves, “can I remove a hardwired smoke detector” The answer is you can！ If you have to stop the hard-wired smoke detectors from beeping, you must unplug them from the clip and remove the battery.
Can I use a ground wire to interconnect smoke alarms
A 12-2 NMB with ground wire will need to be run from your electrical panel to the first smoke detector. From there, a 12-3 NMB wire will need to be run to the second detector, and so forth to each subsequent detector.
Do interconnected smoke alarms use WIFI
Wireless interconnected photoelectric smoke alarms work by using a radio frequency signal to communicate, this eliminates the need to run hard wiring between each alarm.
What are the disadvantages of wireless smoke detector
Disadvantages of a Wireless Fire Alarm System
The system is essentially useless if the batteries aren't charged, since it won't work properly. There is a bit of a burden to homeowners or business owners to always remember to keep the batteries fresh so the system operates properly when you need it most.
How do I stop my smoke alarm from interconnecting
Press the hush/silencing button. It will silence the entire interconnected system. The button may also say “test.” It should silence all the alarms immediately unless there's still smoke and debris. It will reset in eight minutes, given that the smoke and debris have dissipated.
Why do smoke detectors have 3 wires
If multiple smoke detectors are being installed, your electrician will run a 3-wire cable (with ground) from the first smoke detector to each subsequent smoke detector. The extra wire allows the smoke detectors to communicate with one another so that if one smoke detector detects smoke, all detectors will go off.
Are hardwired smoke detectors wired together
A series of hardwired smoke detectors in different rooms are powered by a common electrical cable. The cable runs from one detector to the next in piggyback style. At each detector location, the cable runs into an electrical box. The smoke detector is connected directly to the electrical cable's wires.
How many wireless smoke detectors can be interconnected
As with hardwired units, the NFPA states that up to 18 total units can be interconnected (RF or hardwired) with a maximum of 12 of those being smoke alarms and the balance carbon monoxide alarms.
Do wireless interconnected smoke detectors meet code
Like wired smoke detection systems, wireless smoke detectors are code compliant when they meet NFPA standards. The NFPA 72 sets out certain requirements for wireless smoke detector manufacturing, installation and testing which must be met in order to be code compliant.
Why does my interlinked smoke alarm go off for no reason
The most likely reason smoke detectors go off unexpectedly is that people aren't changing the batteries in them often enough. In most sensors you might think of, the strength of the signal goes up when they detect what they're supposed to.
Can you turn off interlinked smoke alarms
Pressing the hush button on ANY unit will silence the ENTIRE network. If you have interlinking Ei Electronics smoke alarms, only the originating unit's hush button will be able to silence the ENTIRE network. The other units in the circuit can be individually silenced.
How do you stop an interconnected smoke detector
Press the hush/silencing button. It will silence the entire interconnected system. The button may also say “test.” It should silence all the alarms immediately unless there's still smoke and debris. It will reset in eight minutes, given that the smoke and debris have dissipated.
