A "bell" is mentioned in the Visuddhimagga.
In this translation it says,
- And, though sometimes not separate, applied thought is the first impact of the mind in the sense that it is both gross and inceptive, like the striking of a bell. Sustained thought is the act of keeping the mind anchored, in the sense that it is subtle with the individual essence of continued pressure, like the ringing of the bell. Applied thought intervenes, being the interference of consciousness at the time of first arousing [thought], like a bird’s spreading out its wings when about to soar into the air, and like a bee’s diving towards a lotus when it is minded to follow up the scent of it. The behaviour of sustained thought is quiet, being the near non-interference of consciousness, like the bird’s planing with outspread wings after soaring into the air, and like the bee’s buzzing above the lotus after it has dived towards it
A 'bell' is even mentioned in the Dhammapada,
134. If, like a broken gong, you silence yourself, you have approached Nibbana, for vindictiveness is no longer in you.

At least in Sri Lanka bells are used as a "call" to gather everyone at the temple to signal the start of an event.
In some cases like in Siripada as a means to announce how many times you have visited.
