Poly EHS adapters | an add-on, it does not work on its own |
The detector is an add-on to an EHS adapter, not a replacement for one. We are happy to verify the specific phone, adapter and detector combination in advance.
What it is for
An EHS adapter needs to know the phone is ringing so it can signal the headset. On most phones it detects that from the line. On some models it cannot, and an external detector is needed to pick the ring up and pass it on.
This is a typical item that surfaces only during installation. If the customer reports that the EHS answers and hangs up but the headset never announces an incoming call, the detector is usually what is missing.
⚑ atlantis note
When to order it
It does not automatically belong to every EHS adapter. Order it where the specific phone model calls for it, or where installation shows the headset does not announce incoming calls.
It does not replace the adapter
The detector connects nothing on its own. It is always an add-on to an EHS adapter, never an alternative to one.

Frequently asked questions
Do I need one with every EHS adapter?
No. Most phones pass the ring to the adapter themselves. The detector is for models where that does not work.
How do I know it is missing?
The typical symptom is that the EHS answers and ends calls, but the headset never announces that the phone is ringing.
Does it work on its own, without an EHS adapter?
No. It is an add-on to an adapter, not a replacement for one.
