Linear ACT-34B MegaCode 4-Channel Block-Coded Key Ring Transmitter, Black

Deliver secure, dependable access for staff and visitors with the Linear ACT-34B 4-channel MegaCode key ring transmitter. This handheld transmitter is engineered for access control professionals who need a compact, multi-button solution to manage gates, garage doors and controlled entry points. The ACT-34B uses MegaCode block coding (over 1,000,000 unique codes) to reduce code duplication and harden your security posture, while the 318 MHz RF link ensures reliable communication with Linear receivers and controllers.

Designed for low maintenance, the ACT-34B ships with two CR2016 lithium batteries rated for up to five years, minimizing downtime for replacement. A quick-disconnect key ring makes distribution and daily use convenient for staff and contractors, and a built-in 10-second timeout prevents accidental continuous transmission that can disrupt monitoring and surveillance systems. For integrators, block-coded programming simplifies adding multiple transmitters to a system by entering a code range rather than individual IDs.

Ideal for security, surveillance and access control deployments in commercial properties, HOAs and industrial sites. Add the ACT-34B to your next installation to streamline access management and improve overall site security — order now or contact our sales team for bulk and integration support.
