Description:
The BRK Brands, Inc. model SC9120LBLA is a wire-in, 120V 60Hz single and/or multiple
station smoke and carbon monoxide alarm specically designed for residential and
institutional applications including sleeping rooms of hospitals, hotels, motels, dormitories
and other multi-family dwellings. Model SC9120LBLA complies with ULC S531 and CSA
6.19. It meets building codes where AC/DC smoke and carbon monoxide alarms are required
either separately or in combination. The alarms are interconnectable up to 18 devices, of
which 12 can be smoke alarms.
The BRK®SC9120LBLA features a ionization smoke sensing chamber and a carbon
monoxide sensor, an 85dB horn, 10-Year Locked Lithium Battery Backup and a “silence”
feature. The “Intelligent Sensing Technology” system is designed to reduce nuisance
alarms. “Latching Alarm Indication” remembers which unit initiated an alarm. When
interconnected in a series, the unit that triggered the alarm rapidly ashes its red LED
indicator light. After the alarm condition subsides, the initiating unit will store in memory
or “latch” the information and begin to ash the Red 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 allow for true alignment. Other
Contractor Preferred features include a dust cover to keep alarm clean during construction and
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
Installation of this smoke alarm must conform to all Canadian
electrical codes. It is recommended that all units be on the same
fuse or circuit breaker. If codes do not permit, be sure the neutral
wire is common to both phases.

ARCHITECTURAL AND ENGINEERING SPECS
The combination smoke and CO alarm shall be a BRK Model SC9120LBLA and shall provide
at a minimum the following features and functions:
1. An ionization smoke sensing chamber and an electrochemical CO sensor.
2. Powered by 120V AC, 60Hz and have a monitored 10-Year Locked Lithium 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. 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 conrm 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. Silence Feature: Alarm
Silence to temporarily silence nuisance alarms.
8. Two Locking features - tamper resistant locking pins that lock battery drawer and/or alarm to mounting
bracket. Battery drawer is shipped pre-locked so battery will not be discarded prematurely.
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 ULC S531 and CSA 6.19.
