The Linear ACT-22A MegaCode Three Channel Key Chain Remote (part number ACP00606A) is a compact handheld transmitter designed to control up to three garage doors, gates, or access control receivers that use Linear/Nortek’s MegaCode format. Operating on the 318 MHz MegaCode platform, each transmitter is factory-coded with a unique ID that is learned by compatible receivers for secure, reliable operation in residential or commercial applications. The key chain design makes it convenient to carry, while distinct channels let you manage multiple operators or functions from a single remote—ideal as a replacement transmitter or an additional remote for multi-door or shared access setups.
Compatibility is limited to Linear/Nortek devices that support the 318 MHz MegaCode format, such as MegaCode external receivers and operators with built-in MegaCode radio. It is not compatible with Linear Multi-Code (300 MHz) or Delta-3 (310 MHz) systems. Programming is typically completed at the receiver or opener by pressing the Learn/Program button and then activating the desired button on the ACT-22A; repeat for each channel you wish to assign. For safe use, only operate doors and gates within line of sight and with properly installed UL 325 compliant safety devices. Refer to your specific operator or receiver manual for detailed programming steps and memory capacity.
