The Kantech KT-IT100 (DSC IT-100) provides an Application Programming Interface (API) to allow third-party applications to communicate with PowerSeries control panels and form fully integrated control solutions. It is commonly used for integrating Kantech's EntraPass software with DSC PowerSeries alarm control panels, but can be used to connect to any number of home and building automation products.The module features a bi-directional RS-232 interface that accepts commands and sends event-driven or state-change commands to third-party applications to create shared functionality. For example, once a security system is disarmed upon entry, the IT-100 can send a command to an HVAC system to automatically raise the thermostat or send a command to a home automation system to turn on the lights.
