Three on the bell means 'set back' in shunter/guard to driver communication and these will only be used when shunting the train; this is not what you are hearing.

any train from mumbai to secunderabad?
There are several tones broadcast over the PA system.The most common is the one you describe, which is a crew call, meaning the catering crew want to speak to the train manager or vice versa. There is a softer version, which means the driver wants to speak to the train manager. Then there is the "Press For Assistance" button activation. These buttons are located in the toilets and wheelchair areas. The train manager can see which button has been pressed on the train management system computer screen and deal with the problem quickly.
There is another tone to denote that a passenger communication
handle has been pulled, another to denote an exterior door fault and the loudest of all is the fire alarm, which is a continuous two-tone siren.
