1-Channel Custom Block Coded Key Ring Transmitter ACT-21B by Linear ACP00615

ACT-21B 1-Channel Custom Block Coded Key Ring Transmitter ACT-21B by Linear ACP00615

The Model ACT-21B 1-Channel Block Coded Key Ring Transmitter is designed for use with Nice/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.

Key Features:

• Compatible with all Nice/Linear access receivers and controllers
• Supplied with quick-disconnect key ring
• Sold in lots of 10
• Power: Two 1616 batteries
• Codes: Custom block coded in MegaCode format
• RF frequency: 318 MHz
