Andover Controls TCX867 Fire Alarm Terminal Controller Power Supply

The Andover Controls TCX867 Fire Alarm Terminal Controller Power Supply is a compact, networked controller designed for Andover’s Infinity/Continuum fire alarm ecosystems. It communicates over the Infinet RS-485 field bus, enabling distributed control of connected devices and sensors across a single installation. The unit is powered from 24 VAC at 50/60 Hz and draws about 10 VA, making it suitable for small to mid-size applications, while its three universal inputs (0–5 V) and two 0–10 V analog outputs support flexible sensing and actuator control. A built-in real-time clock is backed up during power loss to preserve timing information essential for coordinated fire alarm sequencing. Panel- or cabinet-mountable, the TCX867 integrates with Andover Controls’ Infinet network to provide reliable, centralized configuration and scalable local control within an Onsite fire alarm system.
