Do hardwired smoke detectors have to be the same brand?

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.

Question 1: Can you mix different types of smoke detectors?
Answer: 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.

Question 2: Can you mix Kidde and First Alert smoke detectors?
Answer: The First Alert BRK ADK-12 Smoke Alarm Adapter Plug 12pk easily connects to competitive Kidde, Fyrnetics, and Lifesaver 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.

Question 3: Are all wired smoke detectors the same?
Answer: Unfortunately, not all smoke alarms are created equal. This is because two different types of sensors exist for detecting fire and smoke. Those two sensors are called “photoelectric” and “ionization” sensors, and they both sense vastly different types of smoke and fire.

Question 4: Can I replace my own hardwired smoke detector?
Answer: You can replace hard-wired detectors yourself if you can reach them and if you have sufficient skill to replace a light fixture. (Be sure to first turn off electricity at the breaker box.) Otherwise, you can hire an electrician or an alarm service company to do the job.

Question 5: Can you mix different brands of hard-wired smoke detectors?
Answer: Absolutely! You can mix and match hardwired First Alert, BRK, and Onelink models. All of our current models use the same wiring harness and connector. We do not recommend mixing different brands since we can only guarantee the performance of First Alert and BRK alarms.

Question 6: Are all hardwired smoke detectors interconnected?
Answer: 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.

Question 7: Which is better First Alert or Kidde?
Answer: First Alert has better features than the Kidde because of the alarm system with a verbal warning of the threat.

Question 8: Are hardwired smoke detectors interconnected?
Answer: 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 detectors, like a photoelectric smoke alarm near the kitchen and a heat detector near the garage.

Question 9: Can I install different brands of hardwired smoke detectors together?
Answer: If your home has hard-wired connections, then you should replace the alarms with hardwired 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).

Question 10: How often do hardwired smoke detectors need to be replaced?
Answer: Because alarm sensors wear out, replace each alarm at least every 10 years. Also, alarms have labels showing when they were made. If you don’t see a label, the alarm is old and must be replaced.
