Boothbay, Maine (NEWS CENTER) -- The Boothbay Fire Department is keeping watch at the town's high school after their fire alarms malfunctioned Friday.

Boothbay Superintendent of Schools Eileen King says students were sent home Friday after school officials discovered the malfunction. King chose to resume classes on Monday with a fire official keeping watch on school grounds, per the fire marshal's office. King says repairs are being made to the alarms.

The Maine Fire Marshal's Office says the person doing the fire watch needs to keep an hourly log notation of the checks. They also need a phone to dial 911 in the event of an emergency and a portable radio to contact the school's secretary for intercom purposes.

According to code, when a fire alarm is out of service for more than 4 hours in a 24-hour period, the building is required to evacuate or have an approved fire watch.

King says Director of Plant Operation Dave Benner compiled a fire watch log broken down by times and floors of the building and copies of the floor plan, room numbers and teacher names. They also have a contact list of telephone numbers.

The alarms are expected to be fixed sometime Monday with normal operations resuming Tuesday.
