• Loud 85 decibel alarm.
• Permanent independent smoke and carbon monoxide sensors.
• Smoke alarm takes precedence when both smoke and
carbon monoxide are present.
• Powered by 120V AC (60 Hz, 25 mA max) wire-in connector.
Model KN-COSM-IB is also equipped with a 9V battery back-
up.
• Model KN-COSM-IB is equipped with Battery Pull Tab that
allows for easy battery connection. Simply pull tab out, and
battery is connected!
• Interconnectable to other Kidde/Nighthawk brand smoke and
CO alarms (see page 16 for details).
• Alarm/Voice message warning system that alerts you of the
following conditions in the manner described below, thus
eliminating any confusion over which alarm is sounding:
FIRE: The alarm/voice pattern is three long alarm beeps fol-
lowed by the verbal warning message “FIRE! FIRE!” This pat-
tern is repeated until the smoke is eliminated. The red LED
light will flash while in alarm/voice mode.
CARBON MONOXIDE: The alarm/voice pattern is four short
alarm beeps followed by the verbal warning message
“WARNING! CARBON MONOXIDE!". This continues until the
unit is reset or the CO eliminated. While powered by battery
only, after four minutes the alarm/voice pattern will sound
once every minute. The red Light Emitting Diode (LED) light
will flash while in alarm/voice mode.
LOW BATTERY(model KN-COSM-IB only): When the bat-
teries are low and need replacing the red LED light will flash
and the unit will “chirp” one time, followed by the warning
message “LOW BATTERY.” This cycle will occur once every
minute and will continue for at least seven days.
