2. Intrusion Detection Technology SafeKey Switching Module
Application
Simple integration and evaluation of Safekey wall readers (WEL/A and WELT/A) for potential-free switching of electrical components, for transferring a set/unset request to a Security Terminal MT/x or to connect to KNX via a push-button interface or binary inputs
Usage
Use of digital chipkeys and / or keycodes for easiest and safest operation
Direct control of electric door openers and garage doors
High-quality stainless steel arming device for KNX security systems
Connection to KNX via Security Terminal, push-button interface or binary input
No exchange of the wall reader lost keys necessary
Use of one key for multiple wall reader
