Which device is represented by code X?

Explanation:
Code X identifies an audible signaling device. A bell is the classic audible alert used in signaling schemes, and it is depicted with a symbol that corresponds to this code. The other items—an exit push-button stick repeater relay, a contact rail alarm indicator light, and a contact rail alarm bell—represent different functions (a relay, a visual indicator, and a different alarm device) that have their own distinct symbols or codes. So the symbol X matches the bell, not the other devices.
