BRK Model 1039753 is a state of the art carbon monoxide alarm designed to provide early warning of the presence of carbon monoxide. It features an electrochemical carbon monoxide sensor and an 85dB horn. It also features a backlit digital display that shows visual confirmation of CO levels, Peak Level Memory, current room temperature and other operating conditions. Backlight illuminates when test button is pressed or unit is in alarm. The sealed 10-year lithium power cell is permanently installed. A full function test switch and a silence feature silences unwanted nuisance alarms. The low power warning indicator will cause the alarm to “chirp” when it reaches the end of its service life and needs to be replaced. The compact, low profile design complements any décor. Designed for wall mounting or tabletop placement (3ft. height or less). Includes mounting anchors and screws.
