Carbon Monoxide Alarm Digital Display Battery Operated 900-0146 KN-COPP-B Kidde

Description 

Kidde 900-0146 (Model KN-COPP-B / KN-COPP-B-LPM) is a standalone, battery-powered carbon monoxide alarm engineered to continuously monitor residential living spaces for hazardous CO gas accumulation. Equipped with an integrated digital LCD screen, the unit provides a continuous visual readout of detected carbon monoxide concentrations from 30 to 999 parts per million (PPM), refreshing its display reading approximately every 15 seconds.

A built-in Peak Level Memory button records and displays the highest CO concentration measured since the last system reset, allowing homeowners and emergency responders to verify gas presence even if an event occurred while the premises were unattended. Featuring a loud 85-decibel pulsing audible horn, an operational test/reset button, and dual LED status indicators, the unit operates completely on AA alkaline batteries to maintain continuous life-safety detection through household electrical power outages. Designed for flexible placement, it can be mounted to an interior wall with the included bracket or placed free-standing on a tabletop, nightstand, or shelf.
