433MHz 4‑Channel Alutech AT‑4L Compatible with AR‑1‑500 500N & AN‑MOTORS garage door operators

1. Project Parameter Details

Product Model: AT-4L

Radio Frequency: 433.92 MHz (compatible with ALUTECH same-frequency automatic door/garage door control system)

Operating Voltage: 3VDC

Compatible with CR2032 button battery

Coding Method: Dynamic Code (Dynamic Code, prevents signal duplication, high anti-theft security level)

Number of Channels: 4 independent control channels, capable of separately managing up to 4 sliding doors, garage doors, and gate control devices.

In open environments, the regular transmission distance can reach 50-100 meters (reduced when affected by obstacles and environmental interference).

2. Appearance dimensions and physical parameters

Body design: A rounded, streamlined matte plastic body with silver-gray decorative strips on the sides. The standard configuration includes a suspension rope and a metal keychain.

Reference for the standard size of the same series AT-4 model: Length 65mm × Width 35mm × Thickness 14mm

Shell material: Wear-resistant ABS matte engineering plastic, resistant to daily impacts and fingerprints.

Main control layout: Four independent physical buttons are set on the top of the front panel, with a built-in transmission indicator light. The buttons adopt a pressing and rebounding structure.

3. Packaging information

The front and back of the packaging box are printed with complete brand information, parameters, and multilingual instructions (Russian + English).

2. Complete operation method

(1) Battery installation and replacement

Use a small Phillips screwdriver to unscrew the 3 screws on the back of the remote control, then lift the rear cover.

Insert the CR2032 button battery according to the positive and negative pole markings.

Replace the rear cover, tighten the screws, and then gently press the button. The top indicator light turns on, indicating that the power is normal.

(Remote Control Pairing Programming (New Pairing Operation))

Receiver Learning Mode: Locate the "Learning" button on the main board of the garage door/gate controller. Press and hold it for 2 seconds. The indicator light on the main board will flash rapidly, entering the waiting pairing state (with a time limit of 5-10 seconds).

New Remote Control: Immediately press the button of the remote control you want to bind to this device and hold it for 1-2 seconds. At this time, the indicator light on the main board will go out or flash again, indicating that the channel pairing is successful.

Bind multiple channels separately: Repeat the above steps, and pair the remaining 3 keys to other gate control devices. Each key independently corresponds to a group of control devices.

Verification Usage: Press the pairing button, and the corresponding device will perform the on/off operation, indicating that the programming is complete.

(3) Daily usage operation

Short press the corresponding channel button once: Control the corresponding door to open/close (some devices support point mode)

The indicator light turns on = Wireless signal is being sent out; The indicator light flickers faintly = Battery is low, replace the CR2032 battery

The dynamic scrolling code changes every time a signal is sent; Ordinary devices cannot copy it, ensuring security.

(4) Troubleshooting tips

Button pressed but the light does not turn on: Replace the new CR2032 battery first, and check if the positive and negative poles are installed correctly

The light is on but the door cannot be opened: ① Confirm that the remote control frequency is 433.92 MHz and matches the controller; ② Re-execute the pairing process; ③ Reduce the distance between the remote control and the door body to avoid walls or metal obstacles.

The signal range becomes shorter: Mainly due to low battery voltage, replacing the battery can restore the transmission strength
