Fans Running at Full Speed Regardless of Occupancy
Most car park jet fan systems in the UAE operate at fixed full speed continuously, regardless of actual CO concentrations or how many vehicles are present. This wastes energy, accelerates fan wear, and drives unnecessary noise.
Manual CO monitoring provides point-in-time readings only, and authority inspections typically require documented purge cycle logs that are often incomplete or filled manually after the fact.
CO-Sensor-Driven VFD Control
Intellicon installs a network of CO sensors at specified zones throughout the car park. A dedicated controller reads sensor data continuously and modulates fan speed through VFDs — running fans only as fast as the measured CO concentration requires.
All purge activations, CO events, and fan speed changes are logged with timestamps, producing an audit trail for authority inspections.
What Intellicon Provides
CO Sensor Network
Wall-mounted electrochemical CO sensors at specified grid points. Quantity and location determined by mechanical design and authority requirements.
VFD Fan Speed Control
VFDs installed on jet fans, controlled by the CO sensor network via the BMS or dedicated controller. Speed varies with CO concentration setpoints.
Fire Alarm Integration
Hard-wired or BACnet/Modbus integration with the existing fire alarm panel. On activation, system switches to purge or smoke-clearance mode per the approved fire strategy.
Dashboard & Logging
Real-time CO concentration display, fan status, alarm logs, and automated purge event records. Exportable for authority inspections.
Commissioning & Documentation
Full commissioning report, point-list confirmation, calibration records, CO setpoint settings, and integration test certificates.
O&M Handover Pack
Operation and maintenance manual, spare sensor list, calibration schedule, and authority inspection report template.
What Depends on Third Parties or Site Conditions
Car-park ventilation control is designed in accordance with the approved mechanical design, fire strategy, project requirements, and applicable authority approvals. The control strategy must be aligned with the fire engineer and mechanical consultant.
CO sensor quantity and placement are determined by the approved mechanical design, not by Intellicon alone.
Fire alarm integration requires documented protocol access, wiring routes, and confirmation from the fire alarm contractor and main contractor.
VFD compatibility with existing fan motors requires motor nameplate review and panel space assessment during the site survey.
Performance outcomes — including energy reduction — depend on existing fan configuration, baseline operating schedule, CO setpoints, system design, installation quality, and commissioning validation.
Authority inspection acceptance is subject to the relevant Civil Defence and building authority requirements for the specific emirate and project.
Frequently Asked Questions
How does CO-sensor-driven car park ventilation work?
CO sensors installed throughout the car park continuously measure carbon monoxide concentrations. When CO levels rise above a set threshold, the control system speeds up the jet fans via VFDs to flush contaminated air. When CO drops, fans reduce speed or stop. This replaces the fixed-speed 24/7 operation common in older UAE car parks.
What authority standards apply to car park ventilation control in the UAE?
Car-park ventilation control is designed in accordance with the approved mechanical design, the project fire strategy document, Dubai Civil Defence (DCD) or Abu Dhabi Civil Defence (ADCD) requirements, and any local authority conditions of approval. The applicable standard depends on the emirate and the specific project approval. Intellicon designs to the standard specified in the consultant's fire strategy.
Will the system still work during a fire alarm activation?
Yes. Fire alarm integration is a standard feature of Intellicon's car park CO control systems. On fire alarm activation, the system switches to a purge or smoke-clearance mode as specified in the approved fire strategy. All integration points are confirmed with the fire alarm contractor and the mechanical consultant during design.
Can you integrate with an existing BMS or fire alarm system?
Integration is subject to documented protocol availability, controller compatibility, point-list review, network access, and third-party system access. Intellicon reviews the existing BMS and fire alarm system during the site survey and confirms integration scope before any commitment.
Do you provide purge cycle logs for authority inspections?
Yes. The control system logs all CO events, fan speed changes, purge activations, and alarm triggers with timestamps. Reports can be exported for authority inspections and FM team review.
