As soon as pupils enter the school they will have to put their phone in their pouch.
"It locks and you need a magnet to unlock it," Ms Quinn said.
"Teachers will have access to a magnet so if we want to use a phone for teaching and learning it can be opened up.
"At the end of the day we will have magnets around the school and the pupils will unlock their pouch as they're leaving."
The school told pupils about the pouch plans during an assembly.
Ms Quinn said the pupils had "the reaction that you would expect".
"They have questions, they are nervous, they are excited," she said.
"We've asked them to have an open mind and to engage with us so we can make it right for the college.
"Already we've had pupils stop at my office or stop staff and give suggestions.
"There will be pupils who this will cause some uncertainty to and we just want to work with them and bring everyone with us."
