Does BRK 9120B replace 4120B?

Does BRK 9120B replace 4120B?

I found an interconnect chart from BRK brands that says that the 9120B is compatible with the 4120B. It simply means that the 9120B and the 4120B can communicate with each other in an interlinked fashion (one alarm sets off all alarms).

Can I replace a hardwired smoke detector?

They are hard-wired into our electrical system, but that doesn’t mean you need an electrician to replace them. Modern hard-wired smoke detectors don’t have wires in the back that need to be connected to loose wires in the ceiling. This connection makes it simple to replace bad or old smoke detectors with new ones.

Can you replace a smoke detector with a different brand?

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.

Is BRK 4120B the same as 9120B?

Answer: Yes. I just replaced 2 very old (older than 10 years) BRK Electronics Model 4120B smoke detectors with these newer First Alert/BRK Brand Model 9120B units. The new smoke detectors are functioning/self-testing normally.

How do I stop my BRK smoke alarm from beeping?

You can silence this Smoke/CO Alarm by pressing the Test/ Silence button on the alarm cover until you hear an acknowledge chirp. After the Test/Silence button is released, the Red LED blinks during the silence mode. This Silence Feature can temporarily quiet the low battery warning “chirp” for up to 8 hours.

How much should it cost to replace a smoke detector?

NFPA recommends that each household install one smoke detector on each floor, inside each bedroom, and outside each sleeping area. The national average cost for installing a smoke detector is between $70 and $150, with most people paying around $112 to install a dual hardwired detector.

Can you replace a hard-wired smoke detector with a battery one?

Replacing a hard-wired smoke detector is almost as easy as replacing a battery-powered version. You’ll also need a non-contact voltage detector (Photo 1) and a wire stripper. Turn off the power at the main electrical panel and disconnect the old alarm (Photo 1).

Is BRK compatible with Kidde?
