Access Control System for Rented Office Space

23.12.2021 - A modular access security system by CES

  • Large office complex and production area: Mechatronic offline locking devices for internal doors
  • Door Controller and software: Individual access rights to all of the doors
  • Update Readers for personnel access gates: employees ID cards to open all other doors for which they are authorized

Hopfgartner Kunststoff and Umwelttechnik creates innovative special solutions made of plastic.­ They are used in areas where liquids or gases must be captured, collected, cleaned or routed.

Large office complex and production area: Economic combination of classic online access control at the external access points

The Hopfgartner workforce now occupies a new company site at Ilmendorf, near Ingolstadt in ­Germany, which comprises a large office complex together with production, storage and cold halls.
The economic combination of classic online access control at the external access points with mechatronic offline locking devices for internal doors was chosen by the developer of the company premises, Fairnett. The choice was the modular AccessOne access control system by CES.
Not every door in the building requires cabling, yet the user still expects the highest level of security and ease of use at all doors. Planning foresight helped to determine the customer’s specific solution that can also accommodate future developments. The three-storey office building offers plenty of space, not only for Hopfgartner but also for three other commercial tenants. The façade of the office complex has a refined, rust-colored look that makes an interesting contrast to the exposed concrete of the adjacent production hall.

Door Controller: equipped with emergency power supply

The AccessOne controller, located in the technical room of the building, maps a wide range of different door situations as well as controlling and monitoring the doors. It is equipped with an emergency power supply and can operate autonomously in the event of a server or network failure, continuing to function without interruption. The controller operates on an entirely standalone basis, ensuring the reliability and security of the doors at all times.
Individual access rights to all of the doors, personnel access gates and roller doors can be defined and managed within the access management software. The access movements – in both temporal and spatial terms – of authorized persons are stored here. The software can also be extended later with numerous additional functions: a multi-client function, time and attendance registration, visitor administration and various others.  This allows each tenant to configure an access control plan appropriate to their individual requirements and to integrate additional systems via interfaces.

Update Readers for personnel access gates are linked to the intercom system via the AccessOne interface

The cabled update readers are installed in the immediate vicinity of the two entrance doors and both personnel access gates. These constantly exchange data with the controller via a data cable. The update readers are built into Siedle Vario housings and linked to the intercom system via the AccessOne interface. To enter the building, employees hold their ID cards (RFID transponders – Mifare, DESFire) in front of the update reader. The authorization on the ID card is checked and updated by the reader in an instant. After this daily update at the site boundary, employees can then use their ID cards to open all other doors for which they are authorized. Information is then exchanged between the cabled access control devices and the offline mechatronic locks via the ID cards. The newly occupied premises of the plastics manufacturer are generously spread over three floors.
The reception, archive, foreman’s office, changing area and common room, plus the technical, server and cleaning areas are all on the ground floor. The two upper floors comprise offices, a kitchen, meeting rooms and the offices for the management and secretaries. These doors are secured with mechatronic locking cylinders that are equipped with batteries and not cabled. After their initial programming, the locks do not need to be individually reprogrammed again, even if the room is used for a different purpose later. This is a decisive time and cost advantage for the system operator.

Blocked When Lost

If an ID card is reported as lost, authorization for that ID card can be instantly cancelled by marking it in the software as blocked. All other ID cards also receive information about the lost ‘colleague’ from the update readers and pass this to the doors in the building. This prevents even the offline locking cylinders from being opened using the lost ID card. The security of the rented areas therefore already begins at the outer doors.

Growing With Demand

Many additional features are available through either the hardware or software; these can be purchased and integrated or installed at a later date. The same applies for interface expansion to other systems. The AccessOne access control system grows on a modular basis along with the requirements of the premises.
Mario Hopfgartner, Technical Director of Hopfgartner Kunststoff and Umwelttechnik said of the manufacturers, “From the genuinely competent advice and project planning, through to the user training and commissioning of the access control system, I have found CES to be a long-term and reliable partner.”
