Default Mysterious False Alarms

If they hard wired (all connected together so if one of them goes off they

One of the batteries is dead out of the box or after they were installed,
someone forgot to pull the plastic tab that activates the battery. Some
detectors are shipped with either a 10 year battiery or a standard 9 volt
allready installed, I guess for the people that install them without a
battery.

Either way I think the system is telling you have a dead battery.

Some charitable organization did some repair work on our house and in
the process, put up smoke alarms-- everywhere. Now for some unknown
reason, and for no apparent cause, one of those bloody smoke alarms
start going beep-- beep -- beep (long pause) beep-- beep-- beep-- beep
(long psuse) beep-- beep....

It's like a psychotic game of hide and go seek: I go running around
the house trying to find out which of those electronic *******s is
driving the family crazy with the noise, but whichever the device is,
it stops and may not make any noise for another long stretch of time.
Since there is no smoke, no fire, there shouldn't be any reason for
smoke alarms to be doing that right? Has anyone else had this kind of
problem? Have any solutions for this kind of bizarre problem?

From the description given I will venture a GUESS that these may be
radio intertied detectors. If they are they are FCC part 15 devices.
That means that they may not cause radio interference and they must
except any interference from licensed users of radio. Any stray radio
signal that is in the same band of frequencies used by the detectors can
set them off. Such signals can be produced by baby monitors, wireless
security systems, wireless video units, and so on.
