Description
Introduction
The ABB TD-C1.1 Gas Detector with Relay Contact (Product ID: 2CDG220023R0011) is engineered to provide safety monitoring for combustible gases in both residential and commercial spaces. Manufactured by ABB, this white, surface-mounted device is designed to detect a wide array of gases including propane, methane, butane, acetylene, city gas, and natural gas. This device is part of our KNX system components range.

Engineered for versatile deployment, the TD-C1.1 can operate as a standalone monitoring unit or integrate directly with the inputs of ABB intrusion and fire alarm control panels, as well as ABB i-bus® KNX devices. The detector requires an external 12 V DC auxiliary voltage supply and delivers a dedicated relay output contact for system alerting and automation triggers.
