Doorbell Wiring for FingerTec Devices

Doorbell Wiring for FingerTec Devices

A doorbell is a small essential device that has become an integral part of our homes and business premises. It serves as a convenient and effective means of alerting occupants to the presence of visitors or deliveries at the front door. 

Gone are the days of knocking on doors or relying on someone to hear a faint tap. With the advent of doorbells, we have transformed the way we identify our guests' arrival and ensure that they are attended to promptly.

This doorbell function is supported by a few of our FingerTec models, including Kadex, R2, R3, FaceID 3, and FaceID 6.

In this chapter We'll look at some advice, the types of doorbells that work with FingerTec models and wiring details.


Step 1, Types of Doorbells.

The FingerTec model only works and is suitable with 12V DC doorbells. This is because the majority of FingerTec devices operate on a 12V DC power supply.




The image above depicts an example of a doorbell that operates on 12V DC electricity.
