I think you need to test and clean your detector, that's may be the reason why it offen goes off. Then check if it is ten years, replace date and so on. replace a new one, hope it works.

Thank you, I will try the interconnected ones

Thank you

want to know if the Interconnect function necessary? I have ordinary ones, but some friends suggest to replace interconnect ones, is that necessary? And another question, I heard that the ionization sensor contain radioactive material, is that real? Hope someone can give me some advice, thank...

Since they are wired smoke detectors, then the main power is 120 AV, so there not must need the 10 years sealed battery. The battery function mainly for the AC power cut down, for emergency only, so I think one year 9V battery is enough. hope it helpful.
