The Linear 109206 Three Wire Adapter is an OEM accessory designed to interface devices that require a three-conductor control connection with compatible Linear access control and operator systems. It provides a clean way to connect control inputs that use separate power, common, and signal leads, helping installers integrate wall stations, receivers, or control relays when retrofitting or replacing components in garage door opener and gate operator applications. As a factory Linear part, it supports reliable operation in residential and commercial access control environments where a three-wire control scheme is specified.
Installation involves terminating the three conductors to the correct control, power, and common terminals per the host device’s installation manual. There is no programming function in the adapter; it serves as a wiring interface only. For safety and to prevent equipment damage, disconnect power before wiring and follow all manufacturer instructions and local codes. Compatibility is model-dependent—use only with Linear systems and accessories that explicitly call out the Three Wire Adapter (part number 109206) in their documentation. This adapter is commonly used as a replacement part during service calls or as a retrofit accessory when adapting legacy three-wire controls within a Linear access control, gate operator, or garage door opener setup.
