The Linear ACT-21A MegaCode gate or garage door opener is ideal when you're looking for something small, convenient and ultra-secure. The ACT-21A ACP00607 is a single-channel key ring transmitter that works with Linear's access control products. It features a 10-second time-out feature that helps you conserve valuable power on its five-year lithium batteries.
This transmitter is programmed in MegaCode format. Each transmitter is programmed with one of more than a million codes before it even leaves the factory, which dramatically reduces the possibility of code duplication. The Linear ACT-21A ACP00607 is:
Compatible with Linear access receivers and controllers that use the same frequency and format
Equipped with a quick-disconnect key ring
Programmed in the factory with one of 1,000,000 possible codes
The Linear ACT-21A comes with the two type-1616 lithium batteries necessary for operation on its 318 MHz frequency. It's lightweight and compact, measuring just 1.25 inches wide, 2.25 inches high and 0.48 inches thick.
