WH-120 3G SIM Card GSM Gate Opener UAE
WH-120 3G GSM Gate Opener is a SIM-card-based remote access controller designed to operate automatic gates, parking barriers, garage doors, rolling shutters and compatible access control systems using a mobile phone.
Authorized users can activate the connected automation simply by calling the SIM card installed inside the WH-120. Because access is provided through the mobile network rather than a conventional short-range gate remote, the controller can be operated from any location where compatible mobile network service is available.
The WH-120 supports up to 200 authorized phone numbers, uses a Nano SIM card, provides NO/NC relay contacts and supports user management through SMS commands.

Open Automatic Gates by Mobile Phone
The WH-120 GSM gate opener allows an authorized mobile phone number to operate a connected automatic gate. A Nano SIM card is installed inside the controller and approved telephone numbers are stored in the device.
When an authorized user calls the SIM number, the controller identifies the incoming caller and activates its relay. The relay then sends the required trigger command to the compatible gate control board.
Up to 200 Authorized Users
The WH-120 supports up to 200 authorized phone numbers, making it suitable for villas as well as properties where multiple residents, employees or drivers require gate access.
Authorized numbers can be added or removed using supported SMS programming commands, reducing the need to provide every user with a physical gate remote.
No Normal Remote Control Distance Limit
A conventional gate remote normally operates only within radio range of the receiver. The WH-120 communicates through the mobile network, so authorized users are not limited by the normal range of a handheld gate transmitter.
Operation depends on compatible mobile-network service being available to both the installed SIM and the user's phone.
NO / NC Relay Output
The WH-120 provides Normally Open (NO) and Normally Closed (NC) relay contacts for integration with compatible gate automation and access-control equipment.
For most automatic gate motors and parking barriers, the relay is connected to the appropriate push-button, START, OPEN or step-by-step command input according to the control-board requirements.
Adjustable Relay Time
The relay activation period can be configured from approximately 0 to 900 seconds. For a standard automatic gate trigger, a short pulse is normally used, while other access-control applications may require a longer relay activation period.

Important Network Compatibility
Before ordering a WH-120 3G/GSM controller, confirm that the exact SIM card and mobile network you intend to use support the network technology and frequency bands of the supplied unit.
Mobile operators can change or retire older network technologies over time. For new installations where long-term mobile-network compatibility is important, compare the WH-120 3G with a compatible 4G LTE GSM gate opener before purchasing.
