Interference on Phone Entry System

Recommended Posts

We have an SES Cat.2 phone entry system installed at a customer location that has "a radio station" faintly coming through the speaker when panel is dialing a resident. I have disconnected the phone line and put a buttset on it - it is on the line itself. If I remember right, in Electronics school I heard somewhere you can place a capacitor across the speaker or phone line somewhere and stop it. Does anyone hear know how to do this or know what I am talking about? Or is it a Phone Co. fix?

If there is a radio station near by, your existing wire is acting as an antenna. Try changing the wire to shielded and you should be good.

Had a similar experience, we the manufacture asked us to reverse the pair and both sides of the connection... That helped a little bit.. we ended up re pulling STP ... that solved all issues PITA tho
