How to connect SMOKE DETECTOR SENSOR with KC868-A64?

[jigneshk5]

Hi, how to connect Smoke sensor (https://www.kincony.com/smoke-detector-sensor.html) with KC868-A64.
These are the pins present in smoke sensor:
RED: 12V
BLACK:GND
WHITE: COM
ORANGE: Normal open
YELLOW: Normal close

I have uploaded KCS_KC868_A64_v1.0.27 firmware in the controller. What is the MQTT topic for receiving data from digital pins?
