What it is

A record of who went where, and a door that closes behind them

Access control replaces a key that anyone can copy and nobody can audit with a credential that can be issued, withdrawn and reported on. A leaver’s card is cancelled the day they leave, a contractor gets access to one floor for one week, and the server room has a list of who opened it and when — which is what an audit or an incident investigation actually asks for.

The engineering is mostly in the doors. Each one has to be surveyed for the lock it can take, whether it is on an escape route, whether it is fire-rated, how it will fail on a power cut, and what happens when the fire panel operates. Getting that wrong produces the two classic faults: a door that cannot be opened from the inside in an evacuation, and a door that unlocks the building the moment the power blinks.

Which is why we design this alongside the fire system rather than after it. Fail-safe and fail-secure are chosen door by door against the escape strategy, the fire alarm interface is wired and proved as part of commissioning, and the handover includes the door schedule, the access levels as configured, and training for whoever will be issuing cards on Monday morning.

Equipment

What the installation is built from

A controller, the readers and locks at each door, and the interfaces that keep the doors legal in a fire.

Door controllers and panelsSized for the doors on each floor, networked back to the server or the cloud service.

Card, fob and mobile credential readersAt the doors that need a credential, in the format the client wants to standardise on.

Biometric readersFingerprint and face, where a credential that can be handed over is not acceptable.

Electromagnetic locks and strikesFail-safe or fail-secure chosen per door against the escape strategy, not per site.

Turnstiles, flap barriers and boom barriersFor lobbies, gates and parking, where the control has to be physical rather than advisory.

Exit devices and break-glass releasePush-to-exit, emergency release and door monitoring — what makes a controlled door a legal one.

Fire alarm release interfaceDoors on the escape route release on a fire signal, proved at commissioning and at every service visit.

Management software and reportingCredential issue and withdrawal, access levels, time zones and the audit trail.

Visitor and contractor managementTemporary credentials with an expiry, so a contractor’s card stops working when the job ends.
