When Access Control Meets Fire Alarms: Managing High Security Without Compromising Emergency Evacuations
Blog
Keeping a building secure is essential, but security measures must never prevent people from evacuating safely in an emergency.
For commercial and public buildings, access control systems help restrict unauthorised entry, protect sensitive areas and manage the movement of staff and visitors. However, when a fire alarm activates, electronically controlled doors must respond correctly so occupants can escape quickly and safely.
At Total Fire Group, we support organisations across the UK with integrated fire, safety and security solutions, helping ensure these systems work together rather than in isolation.
Why fire alarms and access control must work together
Modern access control can include card readers, keypads, electronic locks and centrally managed doors.
During normal operation, these systems help maintain security. During a fire, however, the priority changes. Doors on escape routes must not prevent or delay evacuation.
This means the relationship between the fire alarm and access control should be considered during both fire alarm installation and access control installation.
Depending on the building, a fire alarm activation may need to automatically release selected electronically controlled doors, allowing occupants to exit without using a card, code or other credential.
Designing for safe emergency egress
The way controlled doors respond during an emergency will depend on factors including:
The building’s fire strategy
The location of escape routes and final exits
The type of electronic locking system
Security requirements
The building’s occupants and operational risks
It is also important to consider what happens during a power failure or system fault.
Good access control management should therefore consider more than who can enter a building. It should also ensure people can safely leave when necessary.
Testing interconnected systems
It is not enough to test the fire alarm and access control system separately. Their interaction also needs to be tested.
A fire alarm inspection should help confirm that the alarm system operates correctly, while facilities teams should also understand how connected doors respond when an alarm activates.
Key questions include:
Do the correct doors release?
Do they release immediately?
Can occupants exit without presenting credentials?
What happens during a power failure?
Does everything reset correctly afterwards?
Testing these cause-and-effect sequences is particularly important in larger buildings where fire alarms may interact with access control, lifts, smoke control systems and building management systems.
Why ongoing maintenance matters
Buildings change over time. Internal layouts are altered, new doors are installed and security requirements evolve.
Regular fire alarm maintenance provides an opportunity to identify whether these changes have affected the wider fire safety strategy.
The same applies to access control. Adding an electronic lock to a previously unrestricted door could affect an escape route, so fire safety should always be considered when security systems are modified.
An integrated approach to fire and security
Problems can arise when fire alarm and security systems are designed or maintained independently.
At Total Fire Group, our experience across fire alarm services, access control systems and wider building security allows us to take a coordinated approach.
From fire alarm installation, inspection and maintenance to access control installation and management, we help businesses maintain high levels of security without compromising safe emergency evacuation.
If you are unsure how your electronically controlled doors will respond when your fire alarm activates, Total Fire Group can review your existing fire and security systems and help ensure they work together effectively.
