Do hardwired smoke detectors have to be wired?
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.

Do smoke alarms have to be connected to the mains?
Your smoke alarms are mains-powered, with a standard nine-volt battery backup, so they’ll continue to work even if there’s a power cut. They’re linked, so if one is triggered all of the alarms in the house will sound.
Will hardwired smoke alarm work with just batteries?
Some smoke detectors rely exclusively on batteries for power, but hardwired smoke detectors have a battery that provides power only in the event of an electricity outage, such as could happen during a power outage or other event that interrupts the electrical circuit.
Which is better hardwired or battery smoke detectors?
Hardwired smoke alarms are more dependable as they are connected on a power supply. Once the alarm sounds, they will not stop until turned off. In case of power interruptions, they have battery backups for continuous operation. Battery-powered smoke alarms depend solely on the batteries.
Will hardwired smoke detector work without power?
If the electricity in your home goes out, these alarms automatically switch to their secondary power source, the backup battery. The backup battery should power the alarm for a minimum of 7 days without electricity to keep your home protected. Modern hardwired alarms require a battery backup.
Do smoke and carbon monoxide detectors need to be hardwired?
Living Up to Code
In many communities, it’s actually now required by law for smoke and CO detectors to be hardwired due to new electrical codes. If your home still has battery-operated alarms, depending on where you live your home might be up to code.
Can you have wireless smoke alarms?
Wireless smoke alarms interconnect without the need to be hardwired and help to detect the presence of smoke and carbon dioxide. Early detection of a fire can help to prevent loss of life and minimize damage to domestic and commercial buildings.
Can you use wireless smoke alarms?
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.
Can you replace wired smoke detector with a wireless?
It is not acceptable to replace a hardwired alarm with one that is battery operated. A home must maintain at least the same level of protection as originally required. It is the law.
How long do batteries last in hardwired smoke detectors without power?
If your detector is hardwired into your home’s electrical system, replace the backup battery at least every 6 months and replace the smoke detector itself at least every 10 years.
How long do 9v batteries last in hardwired smoke detectors?

Can I use a battery only smoke detector
Most fire experts just want working smoke alarms, but hardwired is a great choice in spaces that have wiring. If not, we strongly recommend a battery-only with a built-in 10-year battery.”
What is a major concern with battery powered smoke alarms
Major concern with a battery-powered smoke alarm: Ensuring that the battery is replaced on a regular basis. The most up-to-date codes require new homes to have a smoke alarm in every bedroom and on every floor level. Many home fire alarm systems are part of security systems.
Does the NEC require smoke detectors to be on their own circuit
Residential smoke alarms should be wired on a dedicated circuit. It's a good idea to have at least one light or receptacle-on the same circuit, to alert the homeowners in case the circuit breaker ever trips. Interconnected alarms are usually wired in a daisy chain, using 14-3 or 12-3 cable.
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.
Are wireless smoke detectors to code

Can I replace a hardwired smoke detector without turning off power
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.
Why do smoke detectors need batteries if they are hard wired
Hard wired smoke alarms are mains-powered and include a battery as a backup in case of a power failure. As it's unlikely that both the power and battery will fail at the same time, hard wired smoke alarms offer an extremely reliable form of protection.
Can I use a regular 9 volt battery in my smoke detector
Can I use a regular 9-volt battery in my smoke detector Since most smoke alarms now use lithium-ion batteries instead of the traditional 9-volt variety, some wonder if they can use a regular 9-volt battery for a smoke alarm. The answer is no.
