Modification Manual

Aiphone has always recognized that there are features and functions that our products don't have. In response we've created a manual detailing the in-field customization of our units to do some of  the more frequently requested functions. Called the "Modification Manual"  and now in it's fifteenth year, it has been an invaluable source of knowledge for in field technicians. It is available free of charge for the first time here.

All modification are in PDF format and are broken down into 5 levels, based on their difficulty:

Level 1 - Easy - Wire Connection Only
Level 2 - Easy/Moderate - Component Connection to External points
Level 3 - Moderate - Removal and replacement of internal Components
Level 4 - Moderate/Hard - Internal connection or component addition
Level 5 - Hard - Circuit Creation and Internal Addition

Please note that modifying a unit will not void it's warranty unless while doing the modification you damage the unit. Aiphone is not liable for any damaged caused during modification. Modifications should only be performed by a person with the skills and knowledge necessary to successfully complete the modification.


Modifications are available for the following systems AP-M, CCS, IE, LEF, LEM, MC-60/4, MP-S, NEM, RAX/RCX, Relays, TD-H, VC-M, YAZ, YKX.
