The Linear Multi-Code 1099-50 (manufacturer part number 109950) is a single-channel radio receiver designed to add Multi-Code 300 MHz remote control capability to gate operators and compatible access devices. Operating on 12–24 VAC/DC, this compact add-on receiver decodes standard Multi-Code 300 MHz transmitters that use DIP-switch coding and provides a dry-contact output to trigger a gate operator, parking barrier, or garage door opener input. It is commonly used as a replacement receiver for existing Multi-Code systems or as an upgrade to enable Multi-Code compatibility on new or legacy residential and commercial operators that accept a contact-closure signal.
Setup is straightforward: wire the receiver’s power leads to a 12–24V supply, connect the relay output to the operator’s activation terminals, and match the internal DIP switch code to your Multi-Code transmitter(s). For best range, mount the receiver and its antenna away from large metal surfaces and electrical noise sources, following the operator manufacturer’s guidelines. This model is intended for use with Multi-Code brand 300 MHz remotes and keypads that utilize DIP-switch coding; it is not a learn-code or rolling-code system. As with any access-control device, installation should be performed by a qualified technician, and the completed system must be tested to verify proper operation and compliance with safety requirements for automated gates and doors.
