Description:
The BRK Brands, Inc. catalog no. 9120LBL (model 9120B) is a wire-in, 120V AC
60Hz single and/or multiple station smoke alarms specifically designed for resi-
dential and institutional applications including sleeping rooms of hospitals, hotels,
motels, dormitories and other multi-family dwellings as defined in standard NFPA
101. The 9120LBL complies 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 with Silence smoke alarms are required. The alarms are inter-
connectable with up to 18 devices, of which 12 can be smoke alarms.
The BRK® 9120LBL alarm features a dual 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 prema-
turely. 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 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
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. Two locking
features are provided to prevent battery
theft and/or theft of the unit. Con-
nection to AC power is made
with a “Quick-Connect”
wiring harness. Instal-
lation is quick, easy
and cost effective.
