The BRK Brands, Inc. Cat. Nos. 9120 and 9120B are wire-in, 120V AC 60Hz single
and/or multiple station smoke alarms specifically designed for residential and
institutional applications including sleeping rooms of hospitals, hotels, motels,
dormitories and other multi-family dwellings as defined in standard NFPA 101. Models
9120 and 9120B comply with UL217, CSFM, NFPA 72, HUD, FHA and other agencies
that model their codes after the above agencies. They meet building codes where AC
and AC/DC with Silence smoke alarms are required. The alarms are interconnectable
with up to 18 devices, of which 12 can be smoke alarms.
The BRK® 9120 Series alarms feature a dual ionization smoke sensing chamber - screened
for insect protection, an 85dB horn, 9V battery back-up (all versions except model 9120) and
a “silence” feature. 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 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. This will allow fine-tuning on the positioning to
compensate for out of aligned wall studs and to keep the wording level when wall mounting.
A Single button test/silence button eliminates confusion. Depending on what mode the alarm
is in, pushing the button will test, silence, re-test the alarm when in silence and clear the
latching feature. Battery installation and removal can occur while the unit is mounted to
the ceiling or wall via the side load battery compartment. 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. Installa-
tion is quick, easy and cost effective.
