Query: Fire Safety NOT

I had one of these chirping all the time, I thought I had a faulty wiring. After replacing the unit the chirping stopped. And I had to be overseas in Europe for about 5 months. After I left my neighbor called me and said all the smoke alarms were going off in my house. False Alarm ! Luckily I had left a key with him so he had to go in and drag the ladder from the garage and remove all of them since I have high ceilings. Well that stopped the blaring noise which woke up the whole neighborhood but unlucky for me when I got home, he had forgotten my garage lights on which burned lots of watts for 5 months ! So to make a long story short, stay away from this Piece of Junk....
