Narrative:

Aircraft X; an A320 aircraft; arrived at gate with a log gripe concerning the cabin intercommunication data system (cids). The flight crew verbally informed us that they had a cids director-1 and -2 ECAM fault and an evacuate warning that would not silence. Due to previous history of cids and evacuate warning problems; my aircraft electronics technician (aet) coworker; technician Y; and myself determined that we would replace cids directors-1 and -2. The new cids directors were ordered referencing illustrated parts catalog (ipc) 23-73-34 for this aircraft effectivity. The last update of this document was may 2011. During the installation of the cids units; it was noted that the company part numbers (cpn) of the old and new [cids director] units were different. The ipc calls for cpn XXX729 for this aircraft effectivity; however; cpn XXX732 cids units were found installed. We contacted maintenance control for clarification and maintenance controller X agreed that this aircraft effectivity should have the cpn XXX729 cids units installed per ipc 23-73-34; page-1f. Per ipc 23-73-34; page-1; the cpn XXX731 unit is effective only for aircraft Y; [a different A320 aircraft]. Installation and test of both cids directors was accomplished per aircraft maintenance manuals (amm) 23-73-34; with all tests passing and aircraft was then dispatched. A few minutes after the aircraft left ZZZ; my supervisor; found an airbus maintenance tip (mt) in the amm. The maintenance tip was found to have a part number effectivity table that is in conflict with the current ipc. We immediately contacted maintenance control; this time speaking with controller Y; and informed him of the conflicting part number information on these documents. Controller Y concluded that proper procedures were followed and that he would contact the engineering group to correct the documents in question. In addition I submitted a report to engineering about the matter and hope to get a response soon.

Title: A Line Technician; Avionics Technician; and a Maintenance Controller report about conflicting information between their Illustrated Parts Catalog (IPC) and the Airbus Maintenance Manual regarding the correct Cabin Intercommunication DATA System (CIDS) Directors they could use on an A320 aircraft with a CIDS Director ECAM fault and Evacuation Warning that would not silence.

Narrative: Aircraft X; an A320 aircraft; arrived at gate with a log gripe concerning the Cabin Intercommunication DATA System (CIDS). The flight crew verbally informed us that they had a CIDS Director-1 and -2 ECAM fault and an Evacuate Warning that would not silence.
