Questions & Answers

Hi - I'm replacing the BRK 4120 smoke detectors that are in my house. They were manufactured in 2004. Will the BRK 9120 fit exactly into the existing holes in my ceiling or do I have to make modifications? Also, will the 9120 detectors plug into the existing wiring? Finally, will the 9120B fit just like the 9120 or are there any differences? Thanks very much for your time.

The BRK 9120BRK 9120B and the BRK 9120LB are all compatible with the wiring of your 4120 smoke alarm. I would recommend model 9120B which has a battery backup for added safety.

There may be a small difference with the mounting bracket from your 4120 and the new 9120 series but you may be able to use the existing holes. If you should need to make new holes it only requires screwing in 2 screws to hold the mounting bracket.

Does the 9v battery come with each unit?

by Marcia O. on 05-31-2012

This unit is only hardwired into the homes electrical system. There is no battery backup. If you are interested in this model with a battery backup please look at the BRK 9120B (Click Here to View).

If instead you would like a smoke alarm that is not hardwired and is instead fully battery powered please follow this link to see our selection of battery powered smoke alarms (Click Here to View).

I have a BRK4120B unit that is starting to beep and flash a red light occasionally. When I removed the casing, it shows a plug in feature. The rest of our smoke alarms have batteries that we can replace. This does NOT appear to have a capability of removing a battery. What do I do? Your website says that this unit was replaced by BRK9120B.

by Dennis M. on 05-28-2012

For detectors exceeding 7 years of operation (including the older BRK 4120B models), it is recommended that they be replaced to ensure the sensor is working properly. We recommend replacing your old BRK model with the BRK 9120B, which uses a hardwired wiring harness, while also having a battery back-up. The battery is accessible in the back. These units will run primarily of the hardwired power source unless power outage occurs (in which case, it uses battery power).
