Linear ACT-21B Mini Remote Control Transmitter
Linear Mega Code ACT-21B, acp00615
Linear Mega Code ACT-21B block coded single button remote, 318 MHz, key-chain style

The Model ACT-21B 1-Channel 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 pre-programmed 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

Technical: Linear Moore-o-Matic MegaCode format 1-button mini key chain size 2 by 1 transmitter for garage door openers. Factory programmed MegaCode format supports over 1,000,000 codes. Block coded.

Compatibility: Works with ALL Linear MegaCode System products. Smart coding system, no dip switches, 318 MHz frequency.

Includes: 1 Linear ACT-21B Mini Remote Control Transmitter, 3 volt lithium button cell batteries (5 year life), quick-disconnect key ring and programming instructions

The order was shipped almost immediately.
The items were exactly correct (I had a problem previously as there is a similar item that does not take bulk code)
It arrived quickly.
The agent was awesome!
