A home sprinkler system helped save 11 people from a fire early Saturday.

Most of the six children and five adults in the house in the 1600 block of Massachusetts Avenue were asleep when the fire broke out in a back bedroom, according to a Marietta Public Safety news release.

Several adults tried to put the fire out, but it was a single sprinkler head that did the job before the city Fire Department arrived.

The bedroom sustained minor damage, while the rest of the house and all 11 people were fine, the news release said.

The cause of the fire is under investigation.
