Technical Information

How the Unit Determines When to Alarm

Your Kidde alarm uses advanced technology to monitor the environ- ment in your home and warn you of certain levels of CO. An internal microcomputer works together with the sensors inside the alarm to determine the levels of CO in the air. The microcomputer is calibrated to trigger the unit’s alarm before most people would experience any symptoms of CO poisoning.

This Kidde alarm meets the alarm response time

requirements as follows for CO:

At 30 PPM, the unit cannot alarm in less than 120 minutes

At 50 PPM, the unit must alarm within 60-90 minutes

At 100 PPM, the unit must alarm within 10-40 minutes

At 300 PPM, the unit must alarm within 3 minutes.

Accuracy of the Digital Display

Each Kidde CO Alarm is calibrated at a CO concentration of 150 ppm in air, at 80° F (+/- 10° F) and 40% (+/- 3%) relative humidity. Depending on the ambient condition (temperature, humidity) and the condition of the sensor, the alarm readings may vary.

The digital reading tolerances are:

Ambient: 80° F (+/- 10° F), atmospheric pressure +/- 10%, 40% +/- 3% relative humidity

Reading

(Tolerance of display reading)

0-999 PPM

+/- 20% + 15 ppm

Replacement of the Alarm

This CO alarm has an "operational end of life" feature which will indi- cate when to replace the alarm.

Seven years after initial power-up, this unit will “chirp” every 30 sec- onds to indicate that it is time to replace the alarm. A label has been affixed to the side of the alarm that has “Replace by” date printed on it to aid in identifying the date of replacement.

REPLACE THE ALARM IMMEDIATELY! IT WILL NOT DETECT CO IN THIS CONDITION.
