How do I get my home's smoke alarm to not send a signal to the
monitoring company right away?

Even though the system is grounded through a 6' copper rod, there was a
lightning strike that set off the smoke alarm which called the
monitoring company.

A week later, I was broiling something and I left the oven on in case I
needed to put the food in for more time, and though I didn't smell
anything, the smoke alarm went off and it started dialing the monitoring
company within about 2 minutes. I called them and cancelled, but now
I'm afraid to cook anything except by boiling.

What key words should I look for to buy something new?
