I have noticed my new wire antenna in the attic is much more efficient.  

On digital modes one of my smoke detectors is set off by the RF.  It is one that is wired I believe to the security system.  Would a simple fix be to yank it and get a toroid around the the power/comm lines?  

I also have a screw in motion light in the utility room that when I am on digital the light kicks on.  Not as important though as making sure my wife stays asleep.

Every time I key a mike the motion sensor goes off and the light goes on at my place, too.

When I am running my amp (Ameritron AL-811H at about 600 watts) some of the fluorescent lights in my workshop (where my ham gear is located) flicker with the modulation.

I have under-counter lights in the corner of the garage where the ham shack is. On CW the lights flicker and the ceiling speakers in the living room repeat every dit. Not planning on fixing it as it gives that much needed "Mad Scientist" air to the place.

On 6m the stereo in FM picks up the SSB. Donald Duck as background vocals to jazz doesn't work well. Plan to install a high pass filter to fix that.

Interconnected smoke detectors?
The RF is likely inducing a current in the communications traveller between the smokes.  
That is a low voltage, usually 9VDC, circuit.

The smoke detectors are hard wired so when one goes they all alarm.  

I also have one smoke detector that is part of the ADT security system.  

I think the one in question is just hardwired not the ADT one.  

I need to rip it off and see whats what.

I had a Carbon Monoxide detector go nuts when I was talking to Piccolo on 40m. Changed the batteries, and no more problems.

I wouldn't have believed that hot air could be transmitted over RF....

Those are what I was thinking of.  
Usually wired with 12/3 romex.  
The traveller is actually a LV line as I desribed above.

You may have to shield the wring leading to the smoke detector.

Hey I keyed my HT in a Hotel room a month or two ago and heard a loud buzz from the bathroom.  Tried it again and it did it again.  Figured out that on the Freq I was transmitting on it would make the alarm buzz in there.  I put it away.

Your HT was working correctly as a transmitter, as it should.

The alarm in the bathroom was acting as a receiver, as it should not.

Not your problem.
