Linear ACT-21B 1-Button Transmitter (10-Pack) – Action Direct

Upgrade your access control with the Linear ACT-21B MegaCode Transmitter, available from Action Direct in convenient packs of 10. Designed for maximum security and reliability, each single-channel transmitter features over 1 million factory-coded combinations, eliminating the risk of duplicate signals and unauthorized access.

Operating at 318MHz, this keychain-size transmitter is compatible with Linear MegaCode receivers, including MDR, MDRG, AM/II, and AccessPro systems. It does not use coding switches—instead, each transmitter is block coded at the factory, ensuring a unique and permanent code for every unit.

The ACT-21B includes a quick-disconnect key ring, is FCC Part 15 compliant, and features a power-saving internal timer that limits transmission to 10 seconds to extend battery life up to 5 years. Includes two CR1616 lithium batteries per unit.
