No, but there are a few exceptions. For example, you can link wireless interconnect alarms to hardwired alarms using a “bridge” unit (model SA520B). Or you can interconnect your hardwired smart alarms with your hardwired
Some systems such as FirstAlert OneLink allow mixing and matching wired and battery powered, and have them all communicate. At least one of the wired units also has wireless capabilities, and effectively bridges both systems together.
Yes, they do talk to each other and they are standardized. So it does not matter which brands you install. As long as they are wired correctly, when one goes off they all will. Of course we are talking about modern wiring, some houses were not wired to allow for the detectors to signal to the others.
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.
It is not acceptable to replace a hard wired 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.
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.
You can replace the wiring harness with the power on, if you follow a couple of guidelines. One.. work with only one wire at a time. Two, don't let the black wire touch anything while you are splicing it to the new harness, and don't touch the uninsulated portion of the wire with your bare hands.
Smoke alarms are generally required in residential settings. Hard-wired smoke alarms are required in all new construction in local jurisdictions that have adopted IRC standards.
Absolutely! You can mix and match hardwired First Alert, BRK, and Onelink models.
That being said, in terms of fire detection, wireless smoke alarms are just as reliable as hardwired alarms. The battery shouldn't be a problem if you arrange for regular maintenance.
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.
First Alert ADK-12 BRK/Kidde Smoke Alarm Adapter Plugs
The BRK ADK-12 Smoke Alarm Adapter Plug 12pk easily connects competitive alarms without rewiring. This product is compatible with BRK and Kidde Smoke Alarms and saves time and installation costs when retrofitting existing homes or apartments.
Although the electrical code doesn't require that hardwired smoke detectors be connected to their own dedicated circuit, it doesn't hurt to install a new circuit to power these detectors. Hardwired detectors are usually installed by splicing into a general lighting circuit or outlet circuit.
Hardwired interconnection
There are many 240 volt smoke alarms that can be interconnected by using an additional wire which is laid alongside the 240v wiring at the time of installation. This wire connects all the smoke alarms together so that if one activates they all do.
The Kiddie and FireX Alarm models listed have been tested and are interconnect compatible: 1235, 1275, 1276, 1285, i12020, i12040, i12060, i12080, i4618, PE120, PI2000, KN-COSM-IB, KN-COB-IC, KN-COP-IC, AND RF-SM-ACDC.
The specific gravity of Carbon Monoxide is 0.9657 (with normal air being 1.0), this means that it will float up towards the ceiling because it is lighter than regular air.
When interconnected smoke alarms are installed, it is important that all the alarms are from the same manufacturer or are listed as compatible (see manufacturer's instructions for compatible alarms). If the alarms are not compatible, they may not sound.
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.
Interconnected alarms are safer
Interconnected smoke alarms are safer than standalone smoke alarms, because they let you know about an emergency sooner.
Smoke alarms are to be installed in all residential dwellings (single family homes, multi-family homes, hotels, rental properties, dormitories, etc.). Smoke alarms in newly constructed or renovated dwellings are required to be hardwired with a battery back-up, interconnected, and UL-listed. NFPA 720 (2015 ed.).
For new construction commencing August 14, 1992 only, the smoke alarm must be hardwired with a battery backup. For all other homes, the smoke alarm may be battery operated. (Cal. Health & Safety Code § 13113.7.)
According to the United States Department of Homeland Security, and the California Building Code, at least one smoke detector needs to be placed in each of the following areas of your home: On Every Floor Level. In Every Bedroom. In Every Hallway Outside of a Bedroom.
Can I install a hardwired smoke detector myself? While it is technically possible, it is not recommended. Working with your home's electrical system can be dangerous and complex, best left to a qualified electrician.
Why did my fire alarm randomly go off in the middle of the night? This is likely due to one of the common causes like low battery, dirt buildup, humidity, or insects interfering with the sensor.
Every 10 years
Replace your smoke alarm. Some models last as little as 5 years. This includes battery operated and hard-wired alarms. All smoke alarms have an expiration date.
