All perfect praise be to Allah, The Lord of the Worlds. I testify that there is none worthy of worship except Allah, and that Muhammad is His slave and Messenger.
For the ruling on using bells, please refer to Fatwa 85387.
What was mentioned in that Fatwa includes all types of bells (manual, electronic etc). There is no difference in this ruling between a bell that looks like the church bell or one that is different from it. In fact, it becomes more dislikeable when it is similar to that of a church.
Allah knows best.
