Smoke sensor – Utilization of UA20B

I am trying to connect a smoke sensor that emits a contact signal with the UA20B to perform real-time alarm and history management in the Radionode365 service. We would appreciate it if you refer to the connection method and use it.

Use the connection method below to receive an instant alert through Radionode365 in case of a smoke or a hot topic. You can text, phone, or email.

UA20B has the function of supplying 12V DC power at the same time as it detects the current signal and converts it to digital. The advantage is that it can be linked with the smoke detection sensor without a separate power connection.

When there is no smoke, say NC, and when there is smoke, say NO. And you need two types of resistors.
