The IQUEST Office Building in Singapore has completed an intelligent upgrade of its underground parking facility with the deployment of the TSP-CO carbon monoxide monitoring and control system. The project sets a new benchmark for smart air safety management in basement parking environments.
In high-density urban buildings, underground parking garages are typically semi-enclosed spaces where carbon monoxide (CO) generated by idling and moving vehicles can easily accumulate. This poses a direct risk to occupant health and building operation safety. To address this, the IQUEST Office Building implemented the TSP-CO system to enable real-time monitoring, intelligent ventilation control, and multi-level alarm management, significantly improving both air safety and operational efficiency.
The solution fully aligns with Singapore workplace safety and environmental regulations, replacing traditional manual inspections with a fully automated monitoring and ventilation control system. This ensures faster response, higher accuracy, and more reliable risk prevention.
What is the TSP-CO Carbon Monoxide Monitor?
The TSP-CO is an integrated CO monitoring and control device designed for enclosed environments such as underground car parks, commercial buildings, and mechanical rooms. It combines electrochemical sensing, signal output, relay control, and alarm functions in one unit.
Key operating features:
Accurate detection: Equipped with a Japanese electrochemical CO sensor for continuous and precise monitoring
Fast response: 1-second data refresh rate for real-time concentration tracking
Smart control: Dual relay outputs enable staged control of exhaust fans and air dampers based on CO levels
Local and remote alerts: Three-color LED indicator, audible alarm, and optional remote notification support
Core Advantages
Industrial-grade reliability: Stable performance with fast response and consistent data output
Easy system integration: Supports Modbus RTU and BACnet MS/TP for seamless connection to BMS platforms
Energy-efficient ventilation: Fans operate only when CO levels exceed thresholds, reducing unnecessary energy consumption
Long service life & low maintenance: Sensor lifespan up to 5 years with replaceable sensor modules
Why CO Safety Matters in Underground Parking
Underground parking areas are enclosed or semi-enclosed spaces where vehicle emissions can accumulate easily. CO is colorless and odorless, making it difficult to detect without monitoring systems.
Exposure risks include:
Mild overexposure: dizziness, fatigue, nausea, shortness of breath
Severe exposure: CO poisoning with potential life-threatening consequences
Singapore’s Workplace Safety and Health Act requires strict control of CO levels in enclosed parking environments over an 8-hour exposure period. The TSP-CO system supports multiple measurement ranges (0–100 / 200 / 300 / 500 ppm) and customizable alarm thresholds, meeting both safety compliance and green building standards.
System Layout in the IQUEST Underground Parking Facility
The deployment follows a “focused coverage with risk-based densification” strategy:
Priority zones: driving lanes, ramps, entrances, and exits
High-risk areas: poor ventilation corners and high-traffic zones
Coverage radius: each unit covers up to 30 meters, ensuring full coverage without blind spots
Multi-Level Control Strategy
Low-level exceedance: activates localized exhaust ventilation to reduce energy waste
High-level exceedance: triggers full-area ventilation plus audible and visual alarms for rapid response
Centralized management: all devices are connected to the building BMS for real-time monitoring, historical data tracking, maintenance analysis, and compliance reporting
Calibration and Maintenance
The TSP-CO supports on-site zero-point calibration and features a replaceable sensor module. Routine inspections ensure measurement accuracy and prevent false alarms or missed detections.
Results and Impact
Safety performance
24/7 real-time monitoring of CO levels
An early warning system significantly reduces poisoning risk.
Full-area coverage improves overall air quality and occupant safety.
Energy and environmental benefits
Demand-based ventilation reduces unnecessary fan operation
Lower operational energy consumption and maintenance costs
Supports Singapore’s green building standards and ESG performance goals
Conclusion
Through the deployment of the TSP-CO carbon monoxide monitoring and control system, the IQUEST Office Building in Singapore has established an integrated solution combining real-time monitoring, intelligent ventilation, multi-level alarms, and remote facility management.
The system not only ensures compliance with local safety and environmental regulations but also delivers significant energy savings through demand-driven ventilation control. It represents a practical and scalable approach for modern underground parking facilities, commercial complexes, and enclosed infrastructure spaces seeking safer, smarter, and more sustainable operations.
