A loud, piercing beep! So I check every smoke detector in my house - of which there are 4 in my very small 1200 square foot house. Why so many? I'm really not sure, but apparently the builders of this house were very fire safety conscious.
Less than a year ago, I had replaced 3 of the batteries after a similar situation and thought that the green light indicated "good" so I went to all 4 and looked for the green light. The one I didn't replace last time, in my office with the highest ceiling, is the only one without a green light. So I check with my friend who was coming over already and her tall husband was coming over with her before we went out last night. He was coming so I was going to employ his height in my household need.
Now I get back to my plan to sleep for a bit. I lay down in the living room, but cannot get over the beeping. So I move upstairs to my bedroom, find some ear plugs, and take a nap. I endured the beeping until they arrived at 7pm and then the adventure began to end the beeping.
We found out the detector without the green light not only didn't have a battery, but wasn't connected to the system. All of the batteries were replaced but the beeping persisted. The only ended when we disconnected the one downstairs and removed the battery. So the beeping ended, but the system is now down a detector and hopefully not compromised... Hmm... I'm going to have to call the customer service department and see what can be done.
If you thought that's where this story ended, you would be wrong.
Around 3am, I woke up to use the bathroom and thought I heard a beeping noise. This is what I thought was happening:
