In covered car parks, monitoring carbon monoxide (CO) and nitrogen dioxide (NO₂) concentrations is essential to ensuring user safety. Generated by internal combustion engine vehicles, these gases can accumulate in confined spaces and negatively impact air quality if ventilation is not properly managed.
Operators must also comply with regulatory requirements (EN 50545-1), while ensuring that safety systems remain fully operational throughout their lifecycle.
In large car parks equipped with numerous gas detectors, day-to-day operation can quickly become challenging. Technical teams need to be able to identify the source of an alarm, locate faults, verify system status and access event history without having to consult multiple interfaces.
To address these requirements, a V.TOUCH architecture was implemented, combining DALEMANS gas detection systems with the Fuji Electric TS4000 human-machine interface (HMI).
The car park is spread across multiple levels and includes several traffic and parking zones. Gas emissions vary depending on occupancy rates, traffic flow and time of day. The installation was designed to meet several key objectives:
The installation is based on a network of DALEMANS gas detectors distributed throughout the car park.
These detectors continuously monitor gas concentrations and transmit data to the DALEMANS control panels. The control panels manage alarm thresholds, monitor equipment status and automatically trigger associated actions such as ventilation control.
The information collected by the control panels is then centralised on the TS4000 HMI, providing operators with a clear and efficient way to visualise and manage system data. Through the interface, operators can access:
The various parking levels are displayed through graphical synoptic views, enabling rapid identification of the affected areas.
In the event of an alarm, operators can immediately locate the incident, review measured values and verify the status of the relevant equipment. This enhanced visibility improves response times and supports faster decision-making when safety risks arise.
Beyond real-time monitoring, the V.TOUCH architecture also simplifies maintenance activities.
When a detector fault or system anomaly is detected, the information is immediately displayed on the supervision interface. Maintenance teams can quickly identify the issue, locate the affected area and prepare their intervention before arriving on site.
This diagnostic capability helps optimise maintenance operations while maintaining a high level of safety.
Every event generated by the system can be recorded and reviewed through the TS4000 interface. The event history includes:
This traceability provides a valuable operational tool. It supports incident analysis, maintenance tracking and the preparation of documentation required for audits and technical inspections. Operators gain a clear and detailed view of system activity over time.
Gas detection data can be transmitted to third-party supervisory systems via Modbus TCP.
Operators can therefore access alarm information, system statuses and event data generated by DALEMANS equipment directly within their existing building management environment.
This integration supports the centralised management of technical building systems and provides a single point of access to critical operational information.
In this application, the V.TOUCH architecture combines the reliability of DALEMANS gas detection technology with the visualisation and supervisory capabilities of the TS4000 interface.
DALEMANS detectors and control panels provide continuous gas monitoring, alarm management and safety equipment control. The supervision interface enables operators to effectively access, interpret and manage the information generated by the system.
Together, these technologies provide operators, facility managers and maintenance teams with greater visibility across their installations, faster response to operational events and valuable support in maintaining occupant safety, regulatory compliance and uninterrupted car park operations.
