Integrated Security Device Alarm Access Control Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience in operating both alarm and access control devices separately, which can lead to non-compliance with regulations like those set by VdS Schadenverhütung GmbH, and there is a need for a more user-friendly integration of these systems.
Innovation Solution
A security device that combines an alarm system with an access control system using a contactless arming/disarming device, where a user transponder is used to manage status changes and programming, with an interface that blocks impermissible inputs and ensures compliance with regulations by only processing permitted states and commands, and allows unhindered communication between access control devices without affecting the alarm system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate input devices are used for alarm device and access control device, then security and reliability are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines the alarm device and access control device into a single integrated security system with a common input device. The interface unit enables both functions to be operated through one unified interface, reducing the number of separate devices while maintaining security through regulated signal processing and command filtering.
2Reliability
If separate input devices are used for alarm device and access control device, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The common input device is designed to serve multiple functions: it can input arming/disarming commands for the alarm device and access control commands for the access control device. The interface unit routes commands appropriately based on the current operational mode, allowing users to operate both systems through a single universal interface.
Solution Approach 2:
The system dynamically switches between alarm device mode and access control device mode based on the operational state. The interface unit activates or deactivates specific signal processing paths depending on which function is currently permitted, allowing the same physical device to adapt its behavior to different operational requirements.
3Ease of operation
If common input device is used for both alarm and access control, then ease of operation is improved, but reliability and security deteriorate
Solution Approach 1:
The interface unit acts as an intermediary between the common input device and the two separate functional systems (alarm device and access control device). It filters, regulates, and routes signals according to predefined rules and current operational modes, preventing unauthorized or impermissible commands from reaching the alarm device while allowing legitimate access control commands to pass through.
Solution Approach 2:
The signal processing path is segmented into distinct channels: one channel handles alarm device commands and another handles access control device commands. The interface unit selectively activates appropriate channels based on operational mode, ensuring that commands intended for one system cannot inadvertently affect the other, thus maintaining security through functional separation within a unified interface.
4Adaptability or versatility
If interface allows all input signals, then adaptability is improved, but security and compliance deteriorate
Solution Approach 1:
The interface unit changes the acceptance parameters of the input device based on the current operational mode. When in alarm device mode, only arming/disarming commands are accepted; when in access control mode, only access control commands are accepted. This dynamic parameter adjustment allows the system to be adaptable to different operational requirements while maintaining compliance by blocking impermissible commands.

AI summary
A security device consisting of an alarm system and an access control system is described. The alarm system comprises an alarm unit, an arming/disarming device, an input device, at least one user transponder readable by the input device, and a deadbolt. The access control system comprises an evaluation and control unit, a door unlocking device, an input or input/output device, and at least one user transponder readable by the input device or readable and writable by the input/output device. The arming/disarming device of the alarm system includes an interface that is coupled to both the evaluation and control unit and the input device of the access control system.The input device or input/output device of the access control system is combined with the input device of the alarm system, but the arming/disarming device is decoupled by the interface from predefined impermissible input and output signals. The at least one user transponder includes a memory in which access data for the alarm system and the access control system is stored.
