RFID reader, missing proper docs, how to utilize Door Bell wires?

[nardev]

I bought some cheap RFID reader, which is not standalone , so i was thinking to make something with arduino.

This is the reader i got: http://www.ebay.com/itm/322252348733?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

I was able to establish data connection, to read cards and keyboard input, turn on/off buzzer and led, but i don't know how to utilize the Door Bell.

I tried to read any voltage/analog/digital movements on those two wires but i didn't notice anything. As if those are dead.

Seems to me as quite popular reader type, so many out there but no docs how it actually works.

Issue with it is that there are two wires just labeled as "ring" or "Door Bell" and i don't know how to use them.

Here is the only doc i have: https://www.soselectronic.cz/productdata/12/70/19/127019/RFID_CARD_R.pdf



Anyone has any idea, what to do? What to try?

Greetings.

Maybe the wires are shorted when the 'bell' button is pressed?
