It's bed time at the Tyrone house. Seven-year old Katie and four-year old Cami are fast asleep.

"I think for most parents, their kids mean everything to them," says John Tyrone, the girls' father.

But after you tuck in your precious treasures, their safety could be in the hands of your smoke detectors.

We tested it out. We set up the camera and smoke detector about ten feet from the girls' doors.

"It was very loud," says Cheryl Tyrone, the girls' mother.

We let the alarm blast for ten minutes.

The girls don't come out. It's hard for mom and dad to just sit and wait. As a parent, what would you be thinking?

It's been long enough. We take our cameras into their rooms. The light from our camera is what finally makes the girls toss in bed.

After the drill mom and dad are beside themselves...

John Tyrone says, "I have no confidence at this point that the kids would wake up on their own and be able to get out."

Area fire officials say neither should you.

"Research has been done in the past that shows the same thing and future research is working on methods of waking children up," says Alachua County Fire Marshal Mark Smith.

New detectors use voices which fire officials say may help.

"And they have some now that they're working on where you can record a parent's voice so it's a familiar voice that's going to wake the children up and that's shown more success."

But Smith says talking with your kids about fire safety is perhaps the most important thing a parent can do.
