An access control system is more than a face reader or fingerprint scanner. Permissions, the lock, the door closer, exit hardware and backup power must all work together.
Six access control maintenance checks for KZN businesses: inspect readers, locks, door closing, staff credentials, exit devices and backup power. Know when to call a qualified technician.
These are routine checks for business owners and site managers. Leave electrical work, lock adjustments, sensitive security configuration and high-level maintenance to authorised professionals.
6 practical access control checks
- Make sure the door closes and latches properly. A sagging door or badly aligned strike can defeat an otherwise working access system. Report dragging, slamming or doors that remain partly open.
- Test an authorised credential. Check that a permitted face, fingerprint, card or PIN opens only the correct door within its allowed schedule.
- Check that revoked access stays revoked. After staff leave or contractors finish work, remove unneeded users and test that old credentials no longer work.
- Observe the exit route. Request-to-exit buttons and approved emergency-release systems must operate in accordance with the site’s life-safety design. Report any sticking or failure immediately—never bypass or disable escape hardware.
- Inspect the reader and surrounding hardware. Look for damage, moisture, loose mounting, dirty reader surfaces and unusual lock sounds. Clean with manufacturer-approved products only.
- Review events and power warnings. Check forced-door or door-held-open alerts where fitted, controller connection status and any low-battery or UPS faults.
Access permissions deserve regular attention
A common security weakness is not broken hardware but outdated user permissions. Confirm the user list reflects current employees and authorised contractors. Review who has access to safe rooms, stock rooms, server rooms and after-hours entrances.
Keep administrator accounts limited to staff who need them, protect backups and audit logs appropriately, and handle biometric data under applicable privacy requirements.
Don’t DIY lock wiring or fire exits
Electrical locks may be configured differently depending on fail-safe/fail-secure requirements, fire interfaces and the door’s purpose. Avoid changing relay contacts, emergency release connections or lock settings without a qualified installer. A door that opens in a convenient way is not necessarily a legally compliant or safe escape route.
Check both security and safe exit. Access control must prevent unwanted entry without compromising emergency egress.
