Seco-Larm 1-Channel 1-Button DIP-Switch Coded Transmitter

Model Number: SK-919TT1S-BU

The SK-919TT1S-BU uses DIP switch coding technology. Perfect for applications requiring large numbers of transmitters with identical codes. For example, a secured factory site might want all engineers on a project to have access to the same buildings, while another working group might need access to a different set. Similarly, a gated community might want to have one code for all residents, with the ability to change the code if transmitters are lost or stolen.Frequency 315MHz*²
