The Linear ACT-31D MegaCode Single-Channel Block Coded Key Chain Remote with Proximity Tag (ACP00954) is a dual-technology credential designed for streamlined gate, garage door, and access control operation. It combines a one-button 318 MHz MegaCode transmitter for wireless control with an integrated 125 kHz proximity tag for use at compatible door readers, letting users click to open vehicular entrances and present the same fob at a prox reader for pedestrian entry. The single-channel design activates one receiver or operator, and the factory-programmed MegaCode ID supports simple “learn mode” enrollment with Linear/Nortek MegaCode-compatible receivers and operators in residential or commercial applications.
Engineered for MegaCode systems operating at 318 MHz, this block-coded model is supplied in managed number blocks for streamlined database administration in access control platforms. The built-in proximity tag functions like a standard 125 kHz prox credential for compatible readers; format support can vary by system, so confirm reader/format compatibility when ordering. The transmitter provides visual feedback via an LED when the button is pressed, and enrollment typically involves placing the MegaCode receiver into learn mode and pressing the button; the prox tag enrolls or is presented like a typical proximity fob. This remote is intended as a replacement or upgrade for Linear/Nortek MegaCode installations and is not compatible with Multi-Code, rolling-code, or other non-MegaCode formats. For best results, verify system frequency, MegaCode compatibility, and prox format before purchase and programming.
