I am thinking about the Ring Intercom and wondered if anyone has CAME Entrotec devices working. Specifically wired with CAT5/CAT6/CW1308. I think the CAME BPT AGT A200K has a similar wiring setup? Wiring attached. Thanks in advance!
Wiring Key:
DR Door Release. A negative going voltage level to trigger the system’s lock control circuit.
VT 12VDC supply to the handset for LED and call tone functions.
0V 0VDC supply to the handset.
BZ Call tone input. Either AC or DC based tones are amplified and heard through the handset when on-hook.
S2 Microphone signal from handset. 2.5 volt circuit at 150 ohms.
S1 Signal to handset speaker. Rated at 32 Ohms at a ½ Watt.
The AGT A200K handset is for use with a BPT (now owned by Came) System 200, which is a 4-wire analogue system. The terminals for an AGT A200K are as follows:
5 Common
7 Call
8 Speech In (Speaker)
9 Speech Out (Microphone/Door Release)
You’d wire these as follows to the Ring Intercom:
A1 → 5 Common/Ground
A6 → 7 Call
A2 → 8 Speech In (Speaker)
A3 → 9 Speech Out (Microphone/Door Release)
I’m really not sure how you would wire the Ring Intercom to your handset, as your handset doesn’t look like it is compatible with the AGT A200K.
There are a couple of cables unused in the A-harness with the A200K handset, maybe they could be used to support your handset. The best place to ask would be Ring Intercom Support
Unfortunately the Ring Intercom compatability list is very limited, so it’s likely you will have issues when dealing with support (based on Twitter interactions I’ve observed).
For instance, if you’ve got a video handset, then it’s automatically not going to be compatible as far as Ring Support are concerned, even though several video handsets have been shown to work perfectly (the video and audio being handled separately). The BPT System 200 AGATA video handsets being one such example of this.
Also, if your handset is not listed at all, then Ring Support will flat out claim your handset is not compatible, which is nonsense as it really just means they’ve not tested it. It’s very likely your handset model is compatible with another different model that may be listed. I mean, who could seriously believe that Ring has tested every handset make/model ever made? Only Ring Support, it would seem.
None of the BPT AGT A200 variant handsets are explicitly listed under Came BPT (there’s a bunch of manufacturer model numbers that nobody is likely to know, and an “AGT A” entry which may be a catch-all) so you end up using the AS C/200 model which is a compatible predecessor of the A200K.
The model list under Came BPT is actually a bit of a mess and badly needs curating, hopefully it will be cleaned up in future but probably not
Hi guys. I have Entrotec rh3+/ed4
My ring in theory is working. The trouble is that for my system to be fully operational I need to lift the phone handle of the hook, otherwise I can’t open the door. Any ideas on how to modify my existing handset? I attached a picture, the cradle switch is the issue (SW1, sw2). Please let me know if there is any way around that or what handset I could replace mine with to make it work.
Thanks
I am thinking of getting one for my grandparents who really need the help one of these would bring.
Since you’ve managed to get it working, could I ask if it would be possible for you to share the wiring diagram- it would be so helpful and appreciated.
In general it works - I am getting notifications etc. I can open the door but someone needs to buzz first.
The only problem I face is that as soon as I answer the call it gets disconnected in a second or so - so I am unable to talk.
Maybe someone has solution to this issue?
