Consumer Benefits

The Kidde KN-COPP-B-LPM battery operated CO alarm provides continuous monitoring of CO levels, even during power outages when many CO incidents occur. The digital display feature allows for easy viewing of carbon monoxide levels 30-999 PPM (parts per million). The KN-COPP-B-LPM will also detect and store concentration CO levels as low as 11 and up to 999 PPM with its peak level memory display. This alarm includes a slide-out battery door that gives immediate access to the batteries and a safety feature that makes it difficult to close the cover without the batteries being installed. It has a 10-year life and a 10-year limited warranty.

Architectural and Engineering Specifications

- The carbon monoxide alarm shall be Kidde 900-0146-LP or approved equal. It shall be powered by three (3) AA batteries (included). The unit shall have a slide open battery door that allows immediate access to batteries. The temperature operating range shall be between 40 ̊F and 100 ̊F (4 ̊C and 38 ̊C) and the humidity operating range shall be 10% - 95% relative humidity, non-condensing.

- The CO sensor shall be of a fuel cell design and shall meet the sensitivity requirements of Underwriters Laboratories UL2034 Single and Multiple Station Carbon Monoxide Alarms.

- The alarm can be installed on the surface of any wall or table top mounted following the UL/NFPA/Manufacturer’s recom-mended placement guidelines. The alarm shall include a battery lockout system that deters closure of battery door without using three batteries.

- The unit shall incorporate a digital display that meets the sen-sitivity requirements of UL 2034. The display will identify the levels of CO in parts per million (ppm) once that level reaches 30ppm (i.e.: “abnormal” levels).

- The alarm shall include a test button that will electronically simulate the presence of CO and cause the unit to go alarm. This sequence tests the unit’s electronics to ensure proper opera-tion.

- Per UL 2034 requirements, the CO sensor will not alarm to levels of CO below 30 ppm and will alarm in the following time range when exposed to the corresponding levels of CO.

70 ppm CO Concentration 60 – 240 minutes

150 ppm CO Concentration 10 – 50 minutes

400 ppm CO Concentration 4 – 15 minutes

- The unit shall incorporate 2 LED’s. A green LED will flash once every 30 seconds to indicate the alarm is operating properly when power is present. A red LED will pulse to to indicate carbon monoxide has been detected until the device is reset or CO is eliminated.

- The alarm shall include a piezoelectric horn that is rated at 85 decibels at 10 feet. When the unit detects carbon monoxide, the alarm pattern will be four (4) short beeps – followed by five (5) seconds of silence – followed by four (4) short beeps with a cor-responding red LED flash.

- It shall also include a 10-year manufacturer’s limited warranty.
