Keyable speed gates in a daylit corporate lobby
Home/Solutions/Workplace
Workplace & Office Buildings

The politest security failure there is.

Entrance control for offices, headquarters and multi-tenant buildings — where the threat is not a forced door but a held one, and the lobby has to look like a lobby.

The Challenges

What a lobby is actually up against.

Offices rarely fail at the door through force. They fail through courtesy, through visitors, and through nobody knowing who is still upstairs.

01

Somebody holds the door

The credential presented was genuine. The person who followed had none. Every card reader in the building is satisfied, and someone unaccounted for is now on the third floor. Politeness is the attack surface.

02

The visitor card that never came back

Issued at the desk, signed for, and gone. Somewhere in a drawer, a coat pocket or a car. A physical pass that outlives the visit is a credential with no owner and no expiry.

03

Nine o'clock

Most of the day's traffic arrives inside forty minutes. A gate that hesitates turns a lobby into a queue, and the queue is the first thing a client sees on the way to a meeting.

04

Four tenants, one entrance

Different companies, different floors, different hours, different contracts. The building operator has one lobby to give them, and each tenant expects their own rules to hold at it.

05

The timesheet nobody trusts

Attendance recorded on an honour system, or on a separate terminal that people forget. The entrance already knows exactly when everyone arrived; the information is simply thrown away.

06

The roll call at the car park

The alarm sounds, the building empties, and someone at the assembly point has a clipboard and a guess. Without a counted exit, the difference between everyone out and someone missing is an assumption.

The Response

Four things the lobby has to get right.

Keyable anti-tailgating
01 — Tailgating

One authorisation, one passage

Infrared sensor windows run the full height of each inner face and read presence across the whole lane rather than at a single beam. A second body following the first is detected, the wings close on the entry, and the attempt is logged rather than argued about.

This is the part a card reader cannot do. The credential was valid; the problem is that two people used it.

Keyable visitor pass
02 — Visitors

A pass that expires by itself

A visitor credential is a QR code issued for a defined window and read from a phone screen or from paper at the same lane as staff. Nothing is handed over, so nothing has to be recovered.

Contractors, couriers and interview candidates all pass through the same lane under the same rules, and the record of who was in the building is created at the door rather than reconstructed from a signing-in book.

Keyable morning peak
03 — Throughput

Peak without a queue

The published open cycle is 0.7 seconds, adjustable, giving up to 50 people per minute per lane, as published by the manufacturer. Two lanes clear most single-tenant arrivals; four handle a headquarters.

Throughput and security are usually traded against one another. A fast cycle with full-height infrared sensing is how you avoid making that trade at the door.

Keyable fail-open
04 — Evacuation

Open, and counted

On power loss or an alarm the wings release to free passage and stay there, as EN 17352 requires of motorised pedestrian barriers on escape routes.

Because every lane is bi-directional, the exit is a recorded event rather than an absence. The last count of who had entered and not left is available to whoever is holding the list at the assembly point.

Included in a Turnkey Delivery

One lobby, several sets of rules.

In a multi-tenant building the hardware is shared and the policy is not. The entitlement logic behind the gate is what lets one row of lanes serve four different companies without four different lobbies — configured and supported by Keyable Europe on a turnkey delivery.

  • Per-tenant entitlements on shared lanes
  • Time-bounded visitor and contractor passes
  • Attendance recorded at the point of entry
  • Live occupancy for roll call and floor loading
  • Cached entitlements when the network drops
  • Fail-open on power loss, always
How we deliver
Keyable tech
Recommended

Three configurations that suit this sector.

Chosen for what an office lobby actually demands: presence at the front, throughput in the middle, and a taller barrier where the floor is restricted.

KSP · Speed Gate

The main lobby

Slim, quiet and fast, in mirror or champagne finishes that read as furniture rather than security.

  • Open cycle0.7 s
  • Throughputup to 50 / min
  • Passage650–1000 mm
Speed Gates →
KFB · Flap Barrier

Where the lobby is tight

Wings withdraw instead of swinging, so lanes sit hard against a wall or beside a lift core. From 800 mm of floor.

  • Footprint from800 mm
  • Passage600 mm
  • Clearancenone required
Flap Barriers →
KSD · Sliding Barrier

Restricted floors

A taller glass panel for server rooms, trading floors and any threshold where waist height is not a serious obstacle.

  • Panel heightapprox. 1150 mm
  • Passage600 mm

In Place

A multi-tenant headquarters.

Keyable case
Workplace

Four lanes, four tenants

A headquarters building shared by four companies: one row of speed gate lanes on the main lobby, per-tenant entitlements applied at the same hardware, visitor passes issued as time-bounded QR codes, and attendance recorded at the point of entry rather than on a separate terminal.

Because every lane counts in both directions, the building operator has a live occupancy figure for floor loading and for the roll call, without asking anyone to keep a list.

Common Questions

Answers, briefly.

What is tailgating in access control?

Tailgating is a second person entering on someone else's authorisation, usually by following them through a gate that is already open. It is the most common way a controlled building is entered without a credential, and it defeats card readers entirely, because the credential presented was genuine.

How do speed gates stop tailgating?

A column of infrared sensors reads the full height of the lane rather than a single beam, so a second body following the first is detected and the wings close on the entry. One authorisation produces exactly one passage, and the attempt is logged.

How fast do office speed gates need to be?

Fast enough that the morning peak does not queue. Keyable speed gates open in 0.7 seconds, adjustable, giving up to 50 people per minute per lane, as published by the manufacturer. Two lanes will clear most single-tenant office arrivals.

Can entrance gates handle visitors and contractors?

Yes. A visitor pass is a QR code issued for a defined window, read from a phone screen or from paper at the same lane as staff credentials. It expires by itself, so no card has to be recovered at the end of the day.

Can the entrance provide a fire roll call?

Yes, in part. Because every barrier is bi-directional, entries and exits are both recorded and the difference is a live figure for who is still inside. On an alarm the barriers release to free passage, as EN 17352 requires on escape routes, and the last recorded count supports the roll call at the assembly point.
