Siedle Secure: systematic access control
Details about the Secure Controller

The wizard guides the installer through the commissioning process step by step. This practically eliminates any mistakes.

User and access profile administration is web-based – via an intuitive interface – which is handy for property management or the HR department.

Two independent lines permit parallel use of two transfer protocols – Open Supervised Device Protocol (OSDP) or Siedle Vario bus.

Time periods for opening specific doors or for switching functions for any number of users can be created in the 1.000 programs for doors and 1.000 programs for users.

The Secure Controller operates up to eight modules – Siedle code locks or electronic key readers – on each of its two bus lines, i.e. 16 in total. It controls up to four doors.

To control more than four doors, several Secure Controllers are networked directly with one another – without the need for intermediary Siedle devices.

The Secure Controller is system-independent. It can be used in In-Home bus systems and in our Siedle Access Professional IP system.

All inclusive: There are no licence fees for extending the Secure Controller's scope of functions and user database. This makes calculations easier and there are no unforeseen costs.
A small, effective solution: the entrance controller

One Siedle entrance controller controls up to two doors, making it ideal for detached homes. A code lock or an electronic key reader can be connected to each door.

An extension allows the entrance controller to control up to eight doors making it ideal for commercial buildings. The device is installed directly next to the entrance controller on the control cabinet's top hat rail.

Door functions and Siedle transponders are programmed with just six simple buttons on the integrated display. Detailed programming instructions are included with the input controller.

The entrance controller's memory can handle up to 1,000 different transponders – as key fobs or in credit card format – as well as 100 key codes.

Easy transponder detection: readID One

Once connected to a standard computer in Plug+Play mode, the readID One is ready for use.

As soon as a Siedle transponder is held over the read area, the readID One captures the required data and transmits it in CSV or Excel, for example.

The system works with the MIFARE DESfire V2 technology, which is currently considered the most secure radio identification method.

The readID One is particularly useful in locations where a lot of people have access and many users need to be managed. Such as commercial buildings and residential properties.

The readID One is compatible with Microsoft, Linux and Apple operating systems. There are no specific system requirements.

We didn't develop the readID One ourselves. But put through its paces. It meets our strict standards and is therefore Certified for Siedle Secure.

More about the electronic key reader

As a Vario system module, the electronic key can be combined with all other modules and placed freely within the system. The illuminated symbol provides orientation in darkness.


The Siedle transponders are available as a card or key fob. Both formats operate passively and require no batteries. They are maintenance-free, low-cost and environmentally friendly.

Just like all modules, the Siedle electronic key reader can be protected with the Siedle pilfer safeguard controller. The system cannot be opened without destroying it, even with special tools.

What makes the Siedle code lock so secure?

Our code lock is more than just a door opener. It is the control centre for everything that can be switched, from lighting to letterbox release. When combined with a user list in the info module, it also works as a call system.

The keyboard is used to enter the numbers for the code, clear incorrect entries and open the door directly. The door release function can also be controlled by a timer.


Every button is fitted in its own section on the metal front panel. This makes it easier for eyes and fingers to find the right button. The system also features backlighting and a confirmation tone.

The engraved buttons are made from the same solid material as the front panel. They move smoothly and precisely. Each push of a button is confirmed by an acoustic signal.

The Siedle transponders

The Siedle electronic key is available as a card or key fob. Both formats operate passively and require no batteries. They are maintenance-free, low-cost and environmentally friendly.

The Siedle transponders support MIFARE DESfire V2, which is currently the most secure technology for RFID (Radio Frequency Identification).

Our transponders come in sets of three or ten, so that they cover the majority of needs perfectly and unnecessary costs are avoided.

What makes the Siedle fingerprint scanner so special?

The capacitive line sensor is much more precise than thermal sensors, and can detect the fine distinct features of a fingerprint. The sensor also works reliably if the user’s finger is dirty or wet.

Data is protected in line with the General Data Protection Regulation (GDPR). It is not possible to reconstruct the fingerprint from the scanned features.

In the Vario system, the fingerprint reader is a functional module that can be freely positioned within the system.

The fingerprint module is part of the installation level in the Steel and Classic systems. The reader protrudes from a recess in the front of the control panel.

Siedle recommends integrating a pilfer safeguard to protect the premium function module against theft. This features an electronically controlled solid mechanical lock.
