Kidde KN-COB-IC - Manual (Page 16)

5. Alarm Characteristics
If interconnected to other Kidde alarms and the backup battery (if
equipped) is low or missing, or if the unit malfunctions, it will display
other readings (and alarm differently) to alert you of specific conditions.
Please familiarize yourself, and other family members, to the difference
between a CO reading and and indication signifying a problem with the
unit itself.
WARNING: If at any time you test the alarm and it does not
perform as described, have it replaced immediately.
Smoke Alarm Indicator (interconnected with CO Alarms)
When an interconnected Kidde smoke alarm detects smoke, the Kidde
CO alarm will sound a smoke/fire alarm pattern of 3 long beeps, fol-
lowed by 1 second of silence. This cycle repeats as long as smoke signal
persists to alert you of the condition. (For model KN-COP-IC with digi-
tal display: The word “Fire” will scroll across the digital display). If this
happens, leave the premises immediately by your escape plan and call
your local fire department.
WARNING: This unit is not a smoke alarm and will not detect
smoke or fire. It will only alarm for smoke/fire if it receives a signal from
an interconnected Kidde smoke alarm.
NOTE: A smoke/fire alarm will override a CO alarm condition.
