5 of 5 No more chirp November 6, 2019
Reviewer: robert calnen from west hartford, CT United States  
worked like a champ...direct replacement of a 10+year
old 9120B alarm that probably needed an internal cleaning.  chirp is disgusting but the new unit fit perfectly and made me happy that it is still in production.    thank you,     chirp is gone!
