Plastic Anchors (2) 1” Screws (2) Activation of your CO alarm indicates the presence of carbon monoxide gas (CO) which can KILL YOU.General Warnings About Carbon Monoxide Gas WARNING If your CO alarm signal sounds with the 4-beep pattern: This carbon monoxide alarm is designed to detect carbon monoxide gas from ANY source of combustion. It is NOT designed to detect smoke, or any other gas types. The alarm also is equipped with Supplemental Temperature Sensing. This will activate the alarm if the temperature reaches either 135°F or the temperature rises by more than 20°F in a minute or less.The CO alarm becomes susceptible to nuisance alarms when subject to prolonged exposure to certain cleaning supplies, hairsprays and perfume products. Care should be taken to install the CO alarm in spaces that are well ventilated where these types of items are stored or used. Self Adhesive Labels (2) 1. Press and release the Silence Button.2.
