Manufacturer statement checked 26 Oct 2026 · source

“VARIANT NOTE (2026-10-26, availability repair): This listing is Kidde's KN-COB-B-LP, the exact model the sources above describe; the earlier ASIN (B005DZS5YK) was the KN-COB-B-LPM variant, Kidde's discontinued variant, which has its own Kidde data sheet that also cites UL 2034 (QA read 2026-10-26). The original reading follows, unchanged. Kidde's page for the Nighthawk Battery Operated Carbon Monoxide Alarm, model KN-COB-B-LP, read 2026-10-23: three AA batteries included, red and green LEDs, a test/reset button that also silences the alarm. Kidde's product data sheet for KN-COB-B-LP (part 900-0233) says the unit meets the sensitivity requirements of UL 2034 (single and multiple station CO alarms) and lists "UL Listed"; the user guide covers KN-COB-B-LP and tells the owner to replace the alarm at the end of its life. UL's own listing directory was not checked, so UL 2034 is manufacturer-stated here. (The earlier ASIN's listing was the KN-COB-B-LPM variant, which Kidde's site marks discontinued; this ASIN's Amazon title reads "Kidde KN-COB-B-LP Nighthawk Carbon Monoxide Alarm, Battery Operated - 21007268", the model Kidde's pages and guide name, re-read from the catalog 2026-10-26.) Kidde's page says "10-Year warranty" with a note that alarms made before 2013 do not have one; the data sheet says 7-year limited warranty. We do not state a lifespan.”
