The Linear MCT-3 (DNT00089) 3-Channel Remote Transmitter is a high-performance access control solution engineered for seamless integration with Linear Mega Code gate and garage door operators. As a cornerstone of the Mega Code series, this 318MHz transmitter provides professional-grade security and multi-device management for residential estates, gated communities, and commercial facilities.
By utilizing factory-preprogrammed Mega Code technology, the Linear MCT-3 (DNT00089) ensures that each unit is unique, significantly reducing the risk of code duplication or unauthorized signal interception. This 3-channel remote allows users to consolidate multiple access points into a single, compact device, providing an efficient workflow for those managing several entryways.
Key Features & Benefits
- Mega Code Digital Encryption: Each transmitter is factory-programmed with one of over 1,000,000 possible codes, providing maximum security against "code grabbing" or unauthorized entry.
- Three-Channel Versatility: Features three independent buttons, allowing the user to control up to three separate gate operators, garage doors, or specialized access control receivers from a single handheld unit.
- High-Output Signal Strength: The 318MHz frequency is tuned for optimal range and penetration through environmental interference, ensuring reliable operation from a significant distance.
- Durable, Impact-Resistant Housing: The rugged black casing is designed to withstand the rigors of daily use and temperature fluctuations, making it ideal for both vehicle visor mounting and handheld use.
- Simplified Device Mapping: Each button sends a unique signal, allowing for straightforward programming at the receiver level without the need for complex dip-switch configurations.

Installation and Technical FAQ
Q: How do I program the Linear MCT-3 to my gate operator?
A: Programming is performed at the receiver or operator motor head. Locate the "Learn" or "Program" button on your Linear device, press it once, and then press the desired button on the MCT-3 transmitter. The receiver’s LED will typically flash or a click will be heard to confirm the pairing.
Q: Does this remote use internal dip switches for coding?
A: No. The MCT-3 utilizes Mega Code technology, which is factory-preprogrammed. You do not need to set switches; the receiver simply "learns" the unique digital ID of the remote.
Q: What is the typical range of the MCT-3 transmitter?
A: Under optimal conditions with a clear line of sight, the MCT-3 provides a range of approximately 100 to 150 feet. Range may vary based on local radio frequency interference and the construction materials of the gate or garage.
Q: Can I use one button for my gate and another for my garage door?
A: Yes. Provided both the gate and the garage door use Linear Mega Code receivers, you can program each of the three buttons to a different device.
Q: How do I know when the battery needs replacement?
A: The red LED indicator on the front of the transmitter will dim or fail to light when the button is pressed. If you notice a significant decrease in operating range, it is recommended to replace the 9-volt battery.
