So these bells go off 4 times an hour for 24 hours 7 days a week?

Maybe it's a clock tower and chimes for each quarter-hour.

Those tower bells generally just go off between 7am and 10pm tops.

Maybe it's a clock tower and chimes for each quarter-hour.

Even clock towers don't ring their bells twenty four hours a day. (Also, most of them only ring on the hour, not every quarter-hour.)
