The SC9120B is a direct replacement for the discontinued SC6120B.


The BRK Brands, Inc. Cat. No. SC9120B is a wire-in, 120V AC 60Hz single and/or multiple station smoke and carbon monoxide alarm specifically designed for residential and institutional applications including sleeping rooms of hospitals, hotels, motels, dormitories and other multi-family dwellings as defined in standard NFPA 101. Models 9120 and 9120B comply with UL217, CSFM, NFPA 72, HUD, FHA and other agencies that model their codes after the above agencies. They meet building codes where AC/DC smoke and carbon monoxide alarms are required either separately or in combination.

The alarms are interconnectable with up to 18 devices, of which 12 can be smoke alarms.


Separate Separate Smoke & CO Smoke CO - Combination smoke and CO alarm eliminates the need for two electrical boxes and features a permanently installed CO sensor and a dual ionization smoke sensor.

"Intelligent Sensing Technology™" - Microprocessor controlled to reduce nuisance alarms.

Smart 3-wire Interconnect - sends a unique signal for smoke and CO on one interconnect wire

"Latching Alarm Alarm Indication" - When interconnected in a series, the unit that triggered the alarm rapidly flashes its red LED indicator. After the alarm condition subsides, the initiating unit will store in memory or "latch" the information and begin to flash the red LED indicator once every 5 seconds.

"Perfect Mount" system - features a gasketless base and a mounting bracket that keeps the alarm secure over a wide rotation range to allow for true alignment. This will allow fine-tuning on the positioning to compensate for out of aligned wall studs and to keep the wording level when wall mounting.

Single button test/silence - Eliminates confusion. Depending on what mode the alarm is in, pushing the button will test, silence, re-test the alarm when in silence and clear the latching feature.

85dB horn - meets UL standards

Easy access side-load battery drawer - Battery installation and removal can occur while the unit is mounted to the ceiling or wall via the side load battery compartment.

Battery backup power supply - keeps alarm working during a power failure, providing battery is installed properly and is fresh.

Other Contractor Preferred features:

  • A dust cover to keep alarm clean during construction.
  • Keyhole slots in the mounting bracket eliminate the need to remove the junction box screws for installation.
  • Two locking features are provided to prevent battery theft and/or theft of the unit. - Connection to AC power is made with a "Quick-Connect" wiring harness.
  • Installation is quick, easy and cost effective.

Great Replacement with and without CO2
These smoke detectors installed very easily. I was skeptical that the "replacement" would be as simple. Even with 4 units, it didn't take long to install them. So far the new smoke detectors have worked very well. No more occasional chirping in the middle of the night with the 18 year old units, even with a new alkaline battery. I have already recommended them to anyone who needs to replace their smoke detectors. Thank you for making the replacement process easy.
