The BMTI Touch is a modern operating and annunciator terminal with touch function, specifically designed for monitoring power supply systems in medical locations in accordance with DIN VDE 0100-710. As a central component of the HospEC® system, it consolidates the display of operating and fault messages from connected field devices (such as SPR, ILT, or UEI-710 devices) and third-party systems.

Display and Operating Concept

• Touchscreen: The device features a 5-inch, touch-sensitive full-graphic display (480 x 854 pixels), which enables intuitive and clear navigation.

• Status LED and Acoustics: A multi-colored status LED on the edge of the housing indicates the current system status at a glance (Green for normal operation, Yellow for warnings, Red for faults). This is supported by an integrated acoustic signaling device (horn).

• Cleaning Mode: For use in sterile hospital environments, the terminal offers a special cleaning mode that locks the display for at least 10 seconds to prevent accidental inputs while wiping.

Functional Areas (Trades) The BMTI Touch is highly adaptable and, depending on the project configuration, combines the monitoring and control of various technical systems:

• Power Supply: Monitoring of insulation resistance, changeover devices, and battery-based central power supply systems (BPS). Furthermore, insulation tests (ISO tests) on connected IT system monitoring devices can be triggered manually directly via the display.

• Room Control: Manual control of operating theatre lighting, blinds, and switching functions for X-ray and laser equipment.

• Air Conditioning: Display of actual values as well as setting of target temperature, humidity, and operating modes for room air conditioning systems.

• Medical Gases: Status monitoring of medical gas supplies, such as oxygen, vacuum, and compressed air.

Communication and Data Logging

• Interfaces: Data transmission to field and third-party devices is securely handled via CAN bus and Modbus interfaces. The device is also equipped with Ethernet, USB, and digital outputs.

• History Memory: An integrated event memory stores the 200 most recent messages with the exact date, time, and error source, allowing fault histories to be precisely traced.

Installation and Housing The BMTI Touch can be flexibly installed in cavity walls, flush-mounted, or surface-mounted with a corresponding housing. The front panel is liquid- and dust-resistant with an IP54 protection class, while the rear features an IP20 rating.
