Narrative:
Aircraft was placarded under xx-yc. The entire service interphone system was inoperative as was the chime system. I notified maintenance that the cockpit chime had to be operation. Maintenance's answer was to try to change the placard to xx-ya. I explained that item was for the phone system, which is not needed, however, the alerting system was a separate system which is needed. The flight attendants need to be able to chime me if they have an emergency in the cabin. MEL xx-ya needs a note added reminding maintenance that the cockpit chime system must be operation. This is a disturbing trend where maintenance will placard a different item such as a warning light if they are not allowed to placard the system that has failed and is generating the warning light. This must stop.

MAINT'S ANSWER WAS TO TRY TO CHANGE THE PLACARD TO XX-YA. I EXPLAINED THAT ITEM WAS FOR THE PHONE SYS, WHICH IS NOT NEEDED, HOWEVER, THE ALERTING SYS WAS A SEPARATE SYS WHICH IS NEEDED. THE FLT ATTENDANTS NEED TO BE ABLE TO CHIME ME IF THEY HAVE AN EMER IN THE CABIN. MEL XX-YA NEEDS A NOTE ADDED REMINDING MAINT THAT THE COCKPIT CHIME SYS MUST BE OP. THIS IS A DISTURBING TREND WHERE MAINT WILL PLACARD A DIFFERENT ITEM SUCH AS A WARNING LIGHT IF THEY ARE NOT ALLOWED TO PLACARD THE SYS THAT HAS FAILED AND IS GENERATING THE WARNING LIGHT. THIS MUST STOP.
