Hello how may I help you? Hi I need some assistance today. Are you able to set check all of the alarm systems in the house? I need to see if everything is in proper working condition and if there are any problems or batteries that need to be changed. I can run a diagnostic on your Nest Carbon Monoxide Alarm. Yes, please. That sounds excellent. It shows that your battery is operating at 50% and may need to be replaced this year. Ok, thanks a lot! You're welcome, should I remind you about ordering a new battery in the future? Yes please. Can you also please check to see how the fire alarm is doing? I've set a reminder for you. Or smoke detector I mean. It seems that your smoke alarm is functionally operating and no battery change is needed at this time. Excellent. Thanks! :)
