Description:
BRK Model 9120LBLA is a wire-in, 120V AC 60Hz single and/or multiple station smoke alarms
specically designed for residential and institutional applications including sleeping rooms of
hospitals, hotels, motels, dormitories and other multi-family dwellings as dened in standard
NFPA 101. Model 9120LBLA complies with ULC S531, NFPA 72, HUD, FHA and other agencies
that model their codes after the above agencies. They meet building codes where AC/DC with
Silence smoke alarms are required. The alarms are interconnectable with up to 18 devices, of
which 12 can be smoke alarms.
BRK 9120LBLA alarm features an ionization smoke sensing chamber, an 85dB horn and a
“silence” feature. This alarm features a 10 year battery backup. The battery drawer is shipped
pre-locked so battery will not be discarded prematurely. Under normal conditions you should
not have to replace the battery for the life of the alarm. The “Smart 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. After the alarm condition subsides, the initiating unit will store in
memory or “latch” the information and begin to ash the green 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,
keyhole slots in the mounting bracket eliminate the need to remove the electrical box screws
for installation. Connection to AC power is made with a “Quick-Connect” wiring harness.
Installation is quick, easy and cost effective.

INSTALLATION OF ALARM
ARCHITECTURAL AND ENGINEERING SPECS
The smoke alarm shall be a BRK Model 9120LBLA and shall provide at a minimum the
following features and functions:
1. An ionization sensing chamber.
2. Powered by 120V AC, 60Hz and have a monitored 9V 10YR battery backup and a solid
state piezo horn rated at 85dB at 10 ft.
3. A visual LED power-on indicator to conrm unit is receiving power or is in alarm.
4. A full function test button. The test button should check all alarm functions by
stimulating the chamber to simulate a smoke condition, causing the unit to alarm.
5. Silence feature - Temporarily silence unwanted nuisance alarms.
6. The unit shall be capable of operating between 40°F (4°C) and 100°F (38°C) and
relative humidity between 10% and 95%.
7. The unit shall have a gasketless base for easy installation and be capable of keeping
alarm secure over a wide rotation range to allow for true alarm alignment.
8. 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.
9. The unit shall at a minimum meet the requirements of ULC S531, NFPA 72, NFPA
101, and ICC.
10. The unit shall have an “End of Life” signal.
Installation of this smoke alarm must conform to all local electrical
codes and Article 760 of the National Electrical Code (NFPA 70)
and NFPA 72. Interconnected units must meet the following
requirements: Total length of wire interconnecting units should be
less than 1000 feet, be #18 gauge or larger and be rated at least
300V. It is recommended that all units be on the same fuse or
circuit breaker. If local codes do not permit, be sure the neutral
wire is common to both phases.
