The BRK Brands, Inc. model SC9120B is a wire-in, 120V AC 60Hz single and/
or multiple station smoke and CO alarm specifically designed for residential and
institutional applications including sleeping rooms of hospitals, hotels, motels, dor-
mitories and other multi-family dwellings as defined in standard NFPA 101. The
SC9120B complies with UL217, UL2034, CSFM, NFPA 72, NFPA 720, HUD, FHA
and other agencies that model their codes after the above agencies. They meet
building codes where AC/DC with Silence smoke and CO alarms are required ei-
ther separately or in combination. The alarms are interconnectable with up to 18
devices, of which 12 can be smoke alarms.
The BRK
®
SC9120B alarm features a dual ionization smoke sensing chamber and
an electrochemical carbon monoxide sensor, an 85dB horn and a “silence” feature.
“Intelligent Sensing Technology” system is designed to reduce nuisance alarms.
“Latching Alarm Indication” remembers which unit initiated an alarm. When in-
terconnected 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 LED indicator 2 seconds
on, 2 seconds off. The “Perfect Mount” system features a gasketless base and a
mounting bracket that keeps the alarm secure over a wide rotation range to al-
low for true alignment. Other Contractor Preferred features include a dust cover
to keep alarm clean during construction, keyhole slots in the mounting bracket
eliminate the need to remove the electrical 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.
