Good to know - If the CO levels from your fireplace get too high, the Daewoo carbon monoxide alarm and LED light will alert you - Turn the alarm off by pressing the hush button if it's went off accidently - The test button makes sure it's working properly in case there's a real fire - A low battery buzzer will let you know when it starts to run out of juice - Connect other Daewoo alarms wirelessly, so if one of them detects heat, the others activate automatically _____________________________________ PLEASE NOTE: This product is not smartphone compatible.
