Are the Visonic MCT-427 wireless smoke alarms that Comcast installs interconnected, as in when my Visonic smoke alarm one the main floor of my house senses smoke, will the other four Visonic wireless smoke alarms that are part of system also start beeping? OR will only the main system alarm start to sound?
For example, all of the hard-wired 120VAC smoke alarms in my house are all interconnected so that when one goes off, they all do.
As another example, some wireless smoke alarms from other manufacturers such as FirstAlert and Kidde are marketed as wireless interconnected smoke alarms, meaning when one wirelss smoke alarm detects smoke and starts to beep, all of the other wireless interconnected devices will also start to beep.
It seems like having all the smoke detectors in the house interconnected like this is the best way to insure that occupants of the house are alerted to potential danger even if the smoke has set off a smoke alarm that may be too far away to adequately hear.
So.... Are they wirelessly interconnected or not????
