I have 5 wired smoke alarms (Kidde PI2010), when 1 goes off they all go off. They have been going off, usually 2 sets of 3 beeps, some evenings for the past few weeks. I would check the house, no problems, and the alarms will stay quiet for at least 24 hours. I think I figured out the problem last night but I would like your opinions.
I use X10 and Insteon technology to control the lights in my house, they send signals on the house's electrical lines. It occurred to me last night when the smoke alarms go off erroneously the smart home controller is sending a signal to turn off a light in the house. Is it possible that the signal on the electrical line is being interpreted by the smoke alarms to mean that another alarm has detected smoke? This is strange because I have had the alarms for 2 years and the other technology for 6 months and this problem is only a few weeks old.
Has anyone had this problem? If so, any solutions? I am deactivating light turnoff actions in Indigo for now and sending the turnoff commands via my iPhone for now. This way I will not get waken up at 2am. If I go a week with no incident I will reactivate the activities related to turning off the lights. I will first test the 3 X-10 devices and then the Indigo devices in case the signal used by one technology causes the problem and not the other.
