ABB MT/U2.12.2 Security Terminal 2-fold FM (2CDG110111R0011)

Description

Introduction

The ABB MT/U2.12.2 (Product ID: 2CDG110111R0011) is a flush-mounted (FM) 2-fold security terminal engineered for the monitored connection of security technology sensors to the ABB i-bus® KNX system. Featuring two dedicated input channels or zones, this signalling group terminal enables direct integration of security sensors—such as magnetic contacts and passive glass-breakage sensors—into smart building automation networks. This device is part of our KNX system components range.

Designed to function either as a stand-alone security system or in combination with dedicated KNX security modules (such as the SCM/S1.1) or intrusion alarm panels with a KNX interface, the MT/U2.12.2 requires a 12 V DC SELV power supply (e.g., ABB NTU/S 12.2000.1) for complete operational capability.
