Super easy installation

I had to replace my existing hard wired smoke alarm system due to false alarms (system about 11 years old). The kit comes with everything you need, including batteries!

I bought a new battery and installed it.... the smoke-alarm kept chirping. How long will this go on... it seems like "for eternity"! I find devices that don't work per the advertisemnets and directions very disheartening. I...
