1 door to multi-site
Full audit trail
Mon–Fri 8am–5pm. 24/7 emergency line out of hours.
The moment a building has more than a handful of staff, mechanical keys stop working as a security control. Nobody knows who holds what, leavers keep copies, and a lost master means rekeying the site.
Access control replaces that with credentials you can revoke in seconds and a record of every door event. For multi-site organisations it also means one administrator can manage every site from one place, with permissions set by role rather than by habit.
We design the fire interface properly. Every electrically locked door on an escape route is interfaced to the fire alarm to BS 7273-4 and fails safe, so security never compromises evacuation.
Each door assessed for leaf type, frame, escape status and appropriate locking method.
Maglocks, electric strikes, motorised locks and free-exit devices selected per door.
Fobs, cards, PINs or mobile credentials, with a documented issue and revoke process.
Mechanical keys have no audit trail and no revocation. Once a site has more than a handful of staff, contractors and cleaners, nobody can say with confidence who holds what — and a single lost master means rekeying the building.
Access control replaces that with credentials you can withdraw in seconds and a record of every door event. Time profiles keep contractors to the windows they are supposed to be on site, and role-based administration means a site manager can run their own building without being able to touch anyone else’s.
The part that is easy to get wrong is egress. Every electrically locked door on an escape route must release on fire alarm and on power failure, interfaced to BS 7273-4 and tested door by door at commissioning. We record that testing as part of handover.
Audio or video entry panels with handsets or app answering for visitor management.
BS 7273-4 compliant release on alarm activation and on loss of power.
Most sites end up mixing types — mobile for staff, cards for contractors, PIN as a fallback for plant rooms.
Audit trail of entries, refusals and door-forced events, exportable for investigations.
A leaver loses access in seconds — no lock changes, no recovering keys.
Contractors and cleaners get access only in the windows they are supposed to be on site.
Door events give a timeline that supports investigations and insurance claims.
We list every controlled door with its escape status, traffic level and locking requirement.
Access groups, time profiles and administrator roles agreed before installation.
Readers, locks, power supplies, break-glass units and controllers installed and cabled.
Release on fire alarm tested door by door and recorded in the commissioning pack.
Credentials issued, administrators trained, and the revoke process documented.
Escape route doors fail safe — they unlock. Non-escape doors can be specified fail secure. Controllers are battery backed so the audit trail continues.
Yes. Cloud-hosted systems let one administrator manage all sites, with permissions that can be delegated per site if you want local control.
On the larger platforms, yes — starters and leavers can be provisioned automatically, which removes the most common failure point in access control.
Yes. Door events tied to a named credential are personal data, so retention and access to those logs should be defined in your data protection policy.
Start with a door schedule — we will produce it during the survey.
