Operation Method

Match Code: Press learning button K1 for 3 seconds, LED indicator lights, then press any button on the remote. LED flashes twice to confirm.

Add Remotes: Repeat step 1 (Up to 20pcs can be matched).

Delete Code: Press and hold K1 until LED flashes 3 times.

Select Output Mode (DIP Switch):

No.1 ON: Toggle Mode
No.2 ON: Latching Mode
Both OFF: Momentary Mode

Feedback Signal: DIP switch NO.3 ON enables feedback. Remote sounds "Di…" upon successful receiver response.

Working Modes Explained

1. Momentary: Press button = ON; Release button = OFF.

2. Toggle: Press once = ON; Press again = OFF.

3. Latching: Press A = Relay A ON; Press B = Relay B ON (A turns OFF).

Frequently Asked Questions (FAQ)

What is the maximum effective range of the KL-K120LA?

The switch has a measured operation range of up to 6km in open areas with Line of Sight (LOS) using LoRa spread spectrum technology.

Can I change the working mode after installation?

Yes, you can easily switch between Momentary, Toggle, and Latching modes by adjusting the internal DIP switches (No.1 and No.2).

How many remote controls can be paired with one receiver?

One receiver can match and store up to 20 different remote control units using the private learning code system.

What does the "Feedback Signal" function do?

When enabled via DIP switch No.3, the receiver sends a signal back to the remote. The remote will beep to confirm the command was successfully received.

Is the voltage customizable for different power sources?

While the standard model is DC 12V, we offer customization for DC 6V, 9V, 24V, and even AC 220V/380V requirements.

What frequencies are supported?

The standard working frequency is 433MHz, but it can be customized to 315MHz, 868MHz, or 915MHz depending on regional regulations.
