Description:
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.

INSTALLATION OF ALARM
The combination smoke and CO alarm shall be a BRK Model SC9120B and shall provide at
a minimum the following features and functions:
1. An ionization smoke sensing chamber and an electrochemical CO sensor both with a
10 year service life.
2. Powered by 120V AC, 60Hz and have a monitored 9V battery backup and a solid state
piezo horn rated at 85dB at 10 ft. and be capable of self restoring.
3. The unit shall perform self diagnostic tests and issue a malfunction warning (three
chirps) if the unit malfunctions.
4. The unit shall have an “End of Life” signal (5 chirps). This signal should be capable of
temporarily being silenced for up to 2 days. After about 2 days, the signal will resume.
After about 2-3 weeks the signal cannot be silenced.
5. A visual power-on indicator to confirm unit is receiving AC power or has switched to
battery backup mode. Separate LED ‘s to indicate a smoke or CO alarm.
6. The CO sensor is adjusted not to detect CO levels below 30 PPM and will not alarm
when exposed to constant levels of 30 PPM for 30 days. It will alarm at the following
levels: 400 PPM CO between 4 and 15 minutes, 150 PPM CO between 10 and 50
minutes and 70 PPM CO between 60 and 240 minutes.
7. Two Latching features: Alarm Latch to easily identify initiating alarm after alarm
condition has subsided. Low battery latch: to visually identify which unit is in low
battery condition. Two Silence Features: Alarm Silence to temporarily silence nuisance
alarms. Low Battery Silence to silence low battery chirp for up to 8 hours.
8. Two Locking features - tamper resistant locking pins that lock battery drawer
and/or alarm to mounting bracket.
9. The unit shall be capable of operating between 40°F (4°C) and 100°F (38°C) and
relative humidity between 10% and 95%.
10. The unit shall have a plug in connector and be capable of interconnection of up to 18
alarms, 12 of which can be smoke alarms.
11. The unit shall at a minimum meet the requirements of UL217 and UL2034, CSFM,
NFPA 72 and 720 and the ICC.
