Aiphone DAK-2S – Frequently Asked Questions
1) What does the Aiphone DAK-2S adaptor kit actually do in an intercom system?
The DAK-2S is a dual master adapter kit that lets two master stations answer the same door station. It ships as a set of component modules that wire into an existing Aiphone intercom run, so a front desk and a back office (for example) can both pick up the same entrance call.
2) Which Aiphone intercom systems is the DAK-2S dual master kit compatible with?
It is built for Aiphone's C-123L and LEM series intercoms. If your masters are from another Aiphone family, this kit is not the adapter for them.
3) Can I add a third or fourth master station to my LEM system, or is two the limit?
Two is not the ceiling. Additional DAK-2S kits can be stacked to bring more than two masters onto the same system. Budget one kit per expansion step and remember each master still needs its own power supply.
4) Do I need a separate power supply for each master station when using the DAK-2S?
Yes. Every master on the system needs its own power supply. The adapter kit handles the switching between masters, not the power, so plan a transformer or supply per station when you spec the job. The power supplies are not part of the kit.
5) With two masters on one door, can the two stations talk to each other?
No. There is no master-to-master communication with the DAK-2S, and only one master can be in use at a time. If the property manager wants staff-to-staff intercom between the two positions, this kit will not deliver it. It only shares door answering duty.
6) Can I get a bell or chime to ring somewhere else in the building when the door station is pressed?
Use the DAK-2S together with an Aiphone RY-AC/A for external signaling. That pairing is the stated way to drive an outside signaling device off the system, which is how most shops handle a noisy shop floor or a back warehouse where the master's own tone will not be heard.
7) Does the DAK-2S kit include the master stations or the door station?
No. What you get is the adapter modules that connect existing equipment together. Masters, the door station, and the power supplies are all ordered separately, so confirm your C-123L or LEM stations are already on site before you schedule the install.
8) Is the Aiphone DAK-2S meant for commercial buildings or home use?
It is classified as commercial door hardware, and it is an electronic access control accessory rather than a mechanical part. The typical application is a small office, clinic, or multi-tenant entrance where more than one staff position needs to answer the front door.
