KC868-A16 board - wired security system - lxndrbrn - 11-17-2024
I would like to build a home alarm system based on the KC868-A16 board. I plan to document everything as precisely as possible to make it easier for others to follow this path.
Starting point:
My house is wired with copper cables leading to every window, door, and most room ceilings.
I use Home Assistant with the MQTT2Zigbee plugin and mainly Zigbee devices.
The goal:
A wired alarm system with a power backup, integrated into Home Assistant, and with relatively low acquisition costs.
The initial questions are:
1. Can I simply connect a magnetic sensor to the digital inputs?
(If yes, what voltage do they operate on?)
2. Can I connect a 24V siren to the dry contact output?
Could I power it separately using the board’s 12V power supply?
I would greatly appreciate your help.
Thank you very much.
PS.: I am currently designing a 3D case for the board (which I’ll gladly share with the community once it’s ready).
Also ive got many Cases for Mounting of the magnet sensors and the movementdetectors.

1. Yes, it's OK, it can use by dry contact signal. or input dc12v (logical "0"), dc0v (logical "1").
2. if you want use 24v siren. just let KC868-A16 work with DC24V power supply is OK. board support DC12-24V power supply.
we suggest you chose new B16M Controller for your house. Because it made by ESP32-S3 chip. in future, all new firmware update and new functions will based on new controller. KC868-A16 is stop maintenance.

This is the Picture.

Hello dear Admin,
thank you very much for the fast reply.
Unfortunately, I actually bought the older A16 board. The budget for this project is a bit tight and the board seems to meet all my requirements.
Can you please take a look at my drawing?
1. how much voltage would the circuits for Door Magnet 1 and Door Magnet 2 get?
2. can I do this with the 12 v and 24 v power supplies?
3. would Door Magnet 3 and Door Magnet 4 work?
I have, as promised, designed the case for the board. Can I post it here, or should I make a separate post in the forum?

1. how much voltage would the circuits for Door Magnet 1 and Door Magnet 2 get?
-->usually door sensor output two wire, dry contact, not need power supply. just connect to digital input ports and GND is ok.
2. can I do this with the 12 v and 24 v power supplies?
-->why not use one DC24V power supply? KC868-A16 support DC 12-24V power supply.
3. would Door Magnet 3 and Door Magnet 4 work?
--> "Door Magnet" is a sensor? if YES, can't connect to OUTPUT port, you should connect with digital input ports, as same as "Door Magnet1" and "Door Magnet2"
Thanks share your 3D files.

Hi,
I am interested in a similar project.
I am running a Domoticz-based home-made alarm for a long time, using Rasberry Pi GPIOs to connect door/window reed sensors and trigger the alarm sound/light, and I want to update/extend it, so I would like to switch to a A16 board and Home Assistant.
At that time, I had to build a DIY Rasberry Pi HAT to filter out transient spikes that appeared on the sensor lines:
Are the A16 inputs more immune to spikes and EMI than the RPi ? Or do you think I must also precondition the signal by adding RC filters ?
Also, what is the power consumption of the A16 board (not counting MOSFET outputs of course), so that I can choose the right 12V power supply.
Kind regards,
Vincent

1. There is an optocoupler isolation circuit with KC868-A16 digital input ports. You can test.
2. KC868-A16 PCB work current only about 200mA without DC load. suggest use DC12V 2A power supply.

Thanks for the quick reply.
OK, I ordered a board and will report here.
