6. Model KN-COP-DP-LS (with digital display) Operating Characteristics

Whenever the alarm is operating, the digital display will display “0” to indi- cate the unit is monitoring for CO. If the alarm senses dangerous levels of CO, 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.

The following table illustrates the possible digital displays, describes the audible alarm patterns, and the recommended actions to take.

Peak Level Memory

When the Peak Level button is pressed and held, the display shows the highest CO reading taken by the CO alarm since its last reset or power up. The Peak Level display feature will display levels between 11-999 PPM. Although the Peak Level feature will display levels below 30 PPM, these levels will not result in an alarm no matter how long the device is exposed to these levels. The Peak Level feature is helpful in identifying if you have had a CO reading since resetting the alarm.

Concentrations of CO between 1 and 30 PPM can often occur in nor- mal, everyday conditions. Concentrations of CO below 30 PPM may be an indication of a transient condition that may appear today and never reappear. Some CO conditions may start out as low level leaks but could develop into CO concentrations that may become harmful.

Peak Level Memory Reset

Press the Peak Level button; with the button still pressed, press the Test/Reset button for two seconds and release. The number on the dis- play will turn to “0”, the memory will be cleared and the alarm will begin monitoring for CO. The Peak Level memory is also reset when the unit loses power.

7. Maintenance

NOTE: This unit is sealed. The cover is not removable.

Due to the loudness of the alarm, we suggest that you place your fingers over the sounder opening while testing your alarm.

Caution: Continuous exposure to the high sound level of this alarm over an extended period of time may cause hearing loss.

Testing

To test the alarm, press the Test/Reset button. If the unit is operating properly, you will hear 4 quick beeps – followed by 5 seconds of silence

–followed by 4 quick beeps. Units with display will show three “eights” and then show a number – usually around 200). Within several seconds the unit will return to monitor for CO.

Note: You do not need to press the Test button to take a CO read- ing.

Battery Replacement

NOTE: This CO alarm is not battery operated. However, these alarms are equipped with 9 volt battery backup – the 9 volt battery is to supply short term back-up during a power outage.
