Questions and Answers
Can you mix different types of smoke detectors?
Combination alarms that include both types of sensors in one device are available. It is recommended to have interconnected smoke alarms in your home for increased safety.
Can you mix brands of hardwired smoke detectors?
If your home has hardwired connections, it is best to replace the alarms with hardwired smoke alarms of the same manufacturer. Using a different manufacturer may require the assistance of an electrician.
Is photoelectric better than ionization?
A well-designed photoelectric alarm usually outperforms ionization alarms in all fire situations. Ionization alarms are more likely to fail to provide sufficient egress time during smoldering fires.
Are ionization smoke detectors being phased out?
Ionization smoke alarms are being phased out across the fire safety industry, from standalone domestic alarms to commercial panel systems.
Is ionization or photoelectric smoke detector better for the kitchen?
Ionization models are suitable for rooms with highly combustible materials that can create flaming fires. Photoelectric models are best suited for living rooms, bedrooms, and kitchens.
Can you mix and match interconnected smoke alarms?
All modern hardwired smoke alarms from First Alert, Onelink, and BRK can interconnect. It is safe to mix different types of detectors for specific areas.
Do hardwired smoke detectors need to be on the same circuit?
The electrical code does not require hardwired smoke detectors to be connected to a dedicated circuit. They are often installed by splicing into a general lighting circuit or outlet circuit.
Do I need to replace all hardwired smoke detectors?
It is recommended to replace all smoke alarms, including those with ten-year batteries and hardwired alarms, when they are ten years old or if they do not respond properly during testing.
What are the disadvantages of photoelectric detectors?
Over time, the lenses of photoelectric detectors may become contaminated, affecting their sensing range. Additionally, certain types of photoelectric detectors require separate transmitters and receivers, or the use of reflectors.
What are the disadvantages of ionization smoke detectors?
Ionization detectors are not as effective at detecting flaming fires and work best for smaller homes or rooms with lots of cooking. They are more sensitive to fast-burning fires such as grease or paper fires.
Can you mix different types of smoke detectors
Combination alarms that include both types of sensors in one device are also available. To increase safety, families should have their smoke alarms interconnected. This means that smoke detected by one alarm will sound all other alarms in the home as well.
Can you mix brands of hardwired smoke detectors
If your home has hard wired connections, then you should replace the alarms with hard wired smoke alarms of the same manufacturer. You can use a different manufacturer; however, this may require an electrician to come in and wire in a different plug (also see the interconnection section below).
Is photoelectric better than ionization
The NFPA acknowledges that a well-designed photoelectric alarm will usually outperform ionization alarms in all fire situations, regardless of type and material. During smoldering fires, ionization alarms failed to give sufficient egress time more frequently than photoelectric alarms failed to do so.

Are ionization smoke detectors being phased out
Ionisation smoke alarms are now being phased out across the entire fire safety industry, from standalone domestic alarms to detectors in the largest commercial panel systems.
Is ionization or photoelectric smoke detector better for kitchen
Ionization models are best suited for rooms that contain highly combustible materials that can create flaming fires. These types of materials include flammable liquids, newspapers, and paint cleaning solutions. Photoelectric models are best suited for living rooms, bedrooms and kitchens.
Can you mix and match interconnected smoke alarms
All modern hardwired First Alert, Onelink, and BRK alarms use the same wiring technology, and can interconnect. It's also safe to mix and match several types of hardwired detector, like a photoelectric smoke alarm near the kitchen and a heat detector near the garage.
Do hardwired smoke detectors need to be on same circuit
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 I need to replace all hardwired smoke detectors
"Replace all smoke alarms, including those that use ten-year batteries and hard-wired alarms, when they are ten years old or sooner if they don't respond properly when tested."
What are the disadvantages of photoelectric detectors
Disadvantages of Photoelectric sensorOver coarse of time lens get contaminated.It's sensing range is affected due to color and reflectivity of the target.Thru beam type requires transmitter (Tx) and receiver (Rx) at two separate locations. Retroreflective type requires reflector in addition to Tx/Rx.
What are the disadvantages of ionization smoke detector
Drawbacks of Ionization Smoke Alarms
Ionization detectors are not as good at detecting flaming fires. Because they are more sensitive to fires that break out quickly, such as fast-burning grease or paper fires, ionization batteries work best for smaller homes or rooms where there might be lots of cooking.
Do you need ionization and photoelectric smoke detectors
For best protection, use both types of smoke alarm technologies. For best protection, it is recommended both (ionization and photoelectric) technologies be used in homes. In addition to individual ionization and photoelectric alarms, combination alarms that include both technologies in a single device are available.
Do interconnected smoke alarms need to be on the same circuit
It should be noted that when installing hard wired interconnected smoke alarms, the smoke alarms must be connected to the same circuit. In addition to this, the manufacturer may have limitations regarding the number of alarms that can be interconnected and the distance between interconnected alarms.

Can you replace a hardwired smoke detector with a different brand
Absolutely! You can mix and match hardwired First Alert, BRK, and Onelink models.
How many years do hard-wired smoke detectors last
10 years
But whatever you call them, they should be replaced every 10 years, according to manufacturers and the National Fire Protection Association, a nonprofit organization funded by the fire-protection industry that provides code language for local building departments and certification programs for people in various safety- …
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.
Which is better photoelectric or ionization smoke alarm false alarm
In many tests of both types of smoke alarms, ionization alarms are indeed faster at warning us of a fast fire than photoelectric alarms… but faster by seconds. Meanwhile, photoelectric alarms often pick up on slower fires many minutes before their ionization siblings, if these latter alarms even go off at all.
What is the difference between Kidde ionization and photoelectric
Ionization sensing alarms may detect invisible fire particles (associated with fast flaming fires) sooner than photoelectric alarms. Photoelectric sensing alarms may detect visible fire particles (associated with slow smoldering fires) sooner than ionization alarms.
Are all interconnected smoke alarms compatible
Yes. You can replace a smoke detector with a combination smoke/CO unit. All modern First Alert and BRK alarms use the same wire harness and connector.
How do you connect wired and wireless smoke detectors together
How do you interconnect smoke detectors An electrician can interconnect smoke detectors using a three-way switch, which contains black, red and white wires. To interconnect the detectors, they simply connect the red wires from all the alarms together. It's also possible to buy wireless interconnected smoke alarms.
Can you interconnect hardwired and wireless smoke detectors
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.
Can you mix hard-wired and wireless smoke detectors
