The BRK Brands, Inc. Cat. No CO5120PDBN is a wire-in, 120 VAC 60Hz single 
and / or multiple station carbon monoxide alarm 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. Model CO5120PDBN complies with UL2034, NFPA 720, HUD, 
FHA and other agencies that model their codes after the above agencies. They 
meet building codes where AC/DC 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 CO5120PDBN features an electrochemical carbon monoxide sensor, a
multi-function LCD digital display, an 85dB horn, 9V battery back-up, an End of 
Life and a silence feature. “Intelligent Sensing Technology” is designed to reduce 
nuisance alarms. The peak level function allows for easy viewing of highest CO 
levels detected. “Latching Alarm Indicator” remembers which unit initiated an 
alarm. When interconnected in a series, the unit that triggered the alarm will 
store in memory or “latch” the information and begin to flash the LED indicator 2 
seconds on, 2 seconds off.  A single button test/silence button eliminates 
confusion. 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.
Installation is quick, 
easy and cost
