What to check
- vent, actuator and controls.
- alarm or smoke-control interfaces.
- power supplies and manual controls.
- cause-and-effect and maintenance records.
Plan the next decision
Test and maintain the vent as part of the complete smoke-control strategy. Opening the vent locally does not by itself prove system operation.
Define the person who can authorise work, the access conditions and the outcome required. Where the subject affects safety, security or compliance, use the competent assessment and premises-specific information required for that system.
Records and follow-up
Keep the instruction, findings, action taken, completion evidence and any open recommendation with its owner and due date.

Use the relevant commercial route, browse maintenance and contact the responsible business with the site-specific requirement.

See current official guidance. Apply it to the actual premises and recheck current requirements before relying on time-sensitive details.
Frequently asked questions
Is an automatic opening vent ordinary ventilation?
Its role may be part of a smoke-control system. Establish the design and controls before making changes or treating it as a general ventilation opening.
What records help investigate a fault?
Provide system drawings, controls information, maintenance reports and a description of what happens when the system operates.
