AC Powered with Battery Backup
and Digital Display
Part Number 900-0278 Model KN-COP-DP-B
Description
The Kidde 900-0278 AC Powered, Plug-in carbon mon-
oxide alarm with 2AA battery backup and digital display
is an easy to install unit that provides reliable protec-
tion against the dangers of carbon monoxide. The 2
AA backup batteries offer protection during power
outages, and ship in the unit with pull tab activator for
quick installation.
The digital display feature adds an advanced level of
protection showing CO levels in PPM allowing you to
see if levels change. This display uses LED technology
which allows the CO levels to be visible in dark condi-
tions and further distances than other alarms that use
less visible LCD components. The display will automati-
cally adjust brightness level to adapt to ambient light
conditions, which offers both a brighter display during
lighted environments and dims to provide a visible, but
softer contrast at night. The display deactivates when
AC power is removed to conserve battery life.
The Kidde 900-0278 has a 10-year operational life,
which provides a 40% longer lifespan than other plug-
in CO alarms. The alarm includes a 10-year limited war-
ranty, and is listed by UL to the UL2034 Standard.
