I have a gate entry application using a HID extended range reader with an Aiphone 1-LED.

Reader is causing a clicking noise on intercom.  Anyone have a solution devices are mounted on a goose neck 3 inches apart.

Is the intercom wire shielded/STP?

Two thoughts:

Is the reader being powered by a linear power supply? And is the system tied to a solid earth ground? 

Good luck!

No ground on Goose neck its 100 feet from a controller. The reader is powered off the controller that is grounded through the power supply and the ground lug on the panel.

We are using the wire recommended by the supplier. I could upgrade to a shielded wire with a drain and ground the drain wire as well.

Is the reader wire shielded?

Is the aiphone power supply 2 or 3 prong?

Are the 110/115vac sources the same for the aiphone and the acp?

Have you tried a paramagnetic ferrite?

Is the aiphone cable outdoor/underground rated?
