WH-120 PRO 4G GSM Gate Opener UAE

The WH-120 PRO 4G GSM Gate Opener is a mobile phone access controller designed for automatic gates, garage doors, parking barriers, rolling shutters and compatible access control systems. It uses a 4G LTE mobile network and Nano SIM card to allow authorised users to activate a connected gate using their mobile phone.

Instead of carrying a traditional gate remote control, authorised users can call the SIM card installed inside the WH-120. The controller identifies the incoming telephone number and activates its relay when the caller is authorised.

The WH-120 PRO provides caller-ID authentication, SMS programming, 4G LTE connectivity, wired switch support and a 3A/240V AC relay output, making it suitable for residential, commercial and industrial gate access applications.

Technical Specifications

4G LTE GSM Gate Opener

The WH-120 PRO uses 4G LTE mobile network communication to provide remote access control for compatible automatic gate systems.

The EMEA version supports multiple LTE FDD and TDD bands, making it suitable for compatible mobile networks in the UAE and other supported regions.

Open Automatic Gate by Mobile Phone Call

A Nano SIM card is installed inside the GSM gate controller. Authorised users call the SIM card number to request gate access.

The WH-120 checks the incoming caller ID against its authorised user list. When the number is recognised, the controller activates its relay output to send the required command to the connected gate control board.

Caller ID Access Control

The WH-120 uses caller ID identification to determine whether an incoming phone number is authorised.

Phone numbers that have not been added to the authorised user list are ignored, helping prevent unauthorised mobile-phone gate activation.

Up to 200 / 1200 Authorised Users

Depending on the WH-120 PRO version, the controller can support up to 200 or 1200 authorised telephone numbers.

This makes the system suitable for villas and private properties as well as larger staff, apartment, warehouse and commercial access applications.

Add & Remove Users by SMS

Authorised telephone numbers can be added or removed using supported SMS text commands.

This allows the system administrator to manage gate-access users without programming individual RF remote controls.

No Traditional Gate Remote Required

Authorised users can operate the gate using their existing mobile phones, reducing the need to issue a separate gate remote control to every user.

Existing gate remote controls can normally remain operational, allowing GSM access to be added as an additional gate-opening method.

Long-Distance Gate Opening

Traditional gate remote controls normally require the user to be within radio range of the receiver. The WH-120 communicates through the mobile network instead.

This allows authorised users to activate the connected gate from remote locations when suitable mobile network service is available at both ends.

Nano SIM Card Gate Controller

The WH-120 PRO uses a Nano SIM card for GSM and 4G network communication.

The SIM card must have active service and be compatible with the frequency bands supported by the selected WH-120 version.

Wide AC/DC Power Input

The WH-120 provides flexible power options with approximately AC 9V–30V and DC 9V–36V input support.

The power source should be correctly selected according to the GSM controller specifications and the existing automation system.

Relay Output for Gate Control Boards

The GSM controller provides a relay output rated at up to 3A / 240V AC.

For automatic gate applications, the relay is normally used as a control signal connected to the appropriate external command input of the gate control board.

Wired Push Button Support

The WH-120 supports connection of a compatible wired switch, allowing local push-button operation to be used together with mobile-phone access.

This provides additional flexibility for security offices, reception areas, guard rooms and other controlled entrances.

4G GSM Controller for Sliding Gates

The WH-120 PRO can be integrated with compatible automatic sliding gate motors that provide an external push-button or access-control input.

When an authorised caller is recognised, the WH-120 relay provides the gate-opening command to the motor control board.

4G GSM Controller for Swing Gates

Automatic swing gate systems can also use the WH-120 as an additional mobile-phone access method.

The GSM relay can be connected to the appropriate command terminals of a compatible swing gate control board.

4G GSM Garage Door Opener

The WH-120 can be connected to compatible garage door openers that accept an external dry-contact or push-button command.

This allows authorised users to activate the garage door using their mobile phone while keeping the existing garage remote controls operational.

4G GSM Parking Barrier Controller

The WH-120 can provide mobile-phone access for compatible automatic parking barriers.

This is useful for residential parking, offices, warehouses, staff parking areas and other controlled vehicle entrances.

GSM Controller for Rolling Shutters

Compatible rolling shutter controllers can also use the WH-120 relay as an external activation input.

The correct connection and relay configuration should be selected according to the rolling shutter controller and required operating function.

Compatible with Automatic Gate Motor Systems

The WH-120 can be integrated with many automatic gate control boards that accept an appropriate external relay or dry-contact command.

Compatibility should be confirmed from the gate motor control-board wiring diagram before installation.

Keep Existing Gate Remote Controls

Installing the WH-120 normally does not require replacing the gate motor's original wireless receiver.

Existing gate remotes, push buttons and compatible access-control systems can continue to operate while the 4G GSM controller provides an additional mobile access method.
