Routine Inspection

• Ensure all vents open and close as required.
• Check manual control points and switches for functionality.
• Test the system's response to alarms or smoke detection.

Cleaning and Lubrication

• Clean the vents and mechanisms to prevent blockages or obstructions.
• Lubricate moving parts to ensure smooth operation.

Electrical Checks

• Inspect wiring and electrical connections for any signs of damage or corrosion.
• Test the control panels and ensure backup power (if applicable) is functioning.

Sensor and Alarm Testing:

• Verify that smoke detectors, heat sensors, and other linked fire alarm components trigger the AOV system as required.

System Calibration

• Adjust settings for vent operation based on the building’s specific needs (e.g., the time the vents remain open during smoke extraction).

Compliance Certification

• After maintenance, ensure the system meets regulatory requirements (e.g., BS 7346 in the UK) and update any necessary certifications.

For professional AOV service and maintenance, contractors like Electrofire Group Ltd or similar specialists can perform these tasks regularly to ensure the system remains in top condition.
