Quick Overview

This is a block coded remote and is designed to work with both MegaCode AP series (AP-5, AP-4, etc...) access controllers and Linear telephone entry systems. It can also be easily programmed into the 10 & 40 capacity MegaCode radio receivers. *** MegaCode block coded remotes will be coded with sequential transmitter numbers if ordered in lots of 10. If not ordered in multiples of 10 then transmitter numbers may not be sequential. Starting transmitter number will be random. ***Check Out Our MegaCode ACT-21B Compatible
Garage Door Remotes..........



The Model ACT-21B 1-Channel garage door remotes block Coded Key Ring Transmitter is designed for use with Linear's access control products. The Model ACT-21B is a single-channel device supplied with a quick-disconnect key ring. Also included are lithium batteries with a five-year service life. A unique 10-second time-out feature prevents the system from being shut down by a single transmitter transmitting continuously. The transmitter is MegaCode format, which means each transmitter is factory preprogrammed with one of over 1,000,000 codes, virtually eliminating the possibility of code duplication. Because the receiver "learns" each specific code, no unauthorized person can gain access to the system by reprogramming a transmitter. Block coded transmitters are factory programmed to a sequential series of transmitter ID codes. When used with a Linear access controller, transmitters can be locally or remotely programmed into memory by entering the first and last codes of the block into the system. Facility codes can be selected to further customize the system. The ACT-21B is only sold in multiples of 10. You will need to enter the facility code and range you need. If you do not know the facility code or range of your remotes, please contact your installer.
