Carbon Monoxide Safety Technical Specifications
This Kidde alarm uses NightHawk Electrochemical Sensor
Technology.
Power: 120V AC units: 60 Hz, Current 60 mA max.
(9V battery backup for model KN-COB-LCB-A)
Sensor: Sensor calibrated at 150 ppm (±25 ppm).
Temperature: Operating range: 40˚F (4.4˚C) to 100˚F
(37.8˚C).
Humidity: 5% to 95%RH (non-condensing)
Mounting: Direct Plug-In: No mounting screws needed.
Alarm: 85+ dB at 10’ @ 3.4 ± 0.5 KHz pulsing alarm.
CO Sensor Response Times
The CO sensor meets the alarm response time requirements
as follows:
At 70 PPM, the unit must alarm within 60-240 minutes.
At 150 PPM, the unit must alarm within 10-50 minutes.
At 400 PPM, the unit must alarm within 4-15 minutes.
How the CO alarm determines when to alarm
This Kidde CO alarm uses advanced technology to monitor
the environment in the home and warn of unacceptable
levels of carbon monoxide. An internal microcomputer
works together with the carbon monoxide sensor inside the
alarm to determine the levels of carbon monoxide in the air
and to calculate the rate that CO would be absorbed into
the human body.
The microcomputer is calibrated to trigger the alarm before
most people would experience any symptoms of carbon
monoxide poisoning. Because carbon monoxide is a
cumulative poison, long-term exposures to low levels can
cause symptoms, as well as short-term exposures to high
levels. This Kidde CO alarm has a time weighted alarm, so
the higher the level of carbon monoxide present, the sooner
the alarm will be triggered.

Carbon Monoxide Alarm Procedure
If alarm signal sounds 4 quick beeps, 5 seconds off:
1) Immediately move to fresh air - outdoors or by an
open door or window. Check that all persons are
accounted for. Do not re-enter the premises or
move away from the open door/window until
emergency services responders have arrived, the
premises have been aired out, and your alarm
remains in its normal operating condition.
2) Call your emergency local service
(fire department or 911).
Never restart the source of a CO problem until it has
been corrected. NEVER IGNORE THE SOUND OF THE
ALARM!
PHONE NUMBER
WARNING: Actuation of the CO Alarm
indicates the presence of Carbon Monoxide
(CO) which can KILL YOU.
