Whenever the alarm is operating, the green Power LED is illuminated to
indicate the unit is monitoring for CO. If the alarm senses dangerous lev-
els of CO, the red Alarm LED will flash and the alarm will emit an audi-
ble alarm pattern. 

6. Model KN-COB-IC Operating Characteristics

Whenever the alarm is operating, the green Power LED is illuminated
and the digital display will display “0” to indicate the unit is monitoring
for CO. If the alarm senses dangerous levels of CO, the red Alarm LED
will flash, the digital display will indicate the CO concentration in parts
per million (PPM), and the alarm will emit an audible alarm pattern. 

This alarm will display a “0” if CO concentrations between 0 and 30
PPM have been detected within the last 15 seconds.

When the unit is first powered up, the digital display will show three
“eights” – indicating the alarm is in the start-up mode. The three
“eights” will remain for approximately 20 seconds. After 20 seconds,
the alarm should display “0” and begin monitoring the air for CO and
will continue to do so as long as it receives power.

Operating Characteristics

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.

NOTE:

Reference to battery backup operation is only applicable to units

that are equipped with battery backup option.

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 inter-
connected Kidde smoke alarm.

NOTE:

A smoke/fire alarm will override a CO alarm condition.
