Fire Alarm Control Panel Module Identification via Touchscreen Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commissioning and maintenance of fire alarm and extinguishing control panels are error-prone and time-consuming due to the complex connections of electrical lines with function modules, often resulting in mismatches between planned and actual configurations.
Innovation Solution
A method and system utilizing a display and operating unit for interacting with function modules, allowing for the display and interaction of function module data, reducing the likelihood of errors by facilitating the assignment of data to the correct modules through a communication link between the interaction unit and the operator.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If electrical lines are manually connected to function modules based on circuit diagrams, then the fire alarm control panel can be installed, but errors occur in connecting lines to the wrong function modules
Solution Approach 1:
The system provides automatic feedback by displaying data from the selected function module on the touchscreen, allowing the installer to verify the correct connection. The system reads identification signals from function modules and presents this information to the operator, creating a closed-loop verification process that prevents connection errors.
Solution Approach 2:
The touchscreen interface acts as an intermediary between the installer and the function modules. Instead of directly connecting lines without verification, the installer uses the touchscreen to identify and verify the correct function module before making connections, reducing errors.
2Adaptability or versatility
If the number of function modules increases to handle more participants, then the system capacity increases, but the complexity of commissioning and maintenance increases
Solution Approach 1:
The system performs self-identification by automatically reading and displaying data from function modules when selected. This eliminates the need for manual documentation or complex commissioning procedures, as the system provides its own configuration information through the touchscreen interface.
Solution Approach 2:
The touchscreen interface serves multiple functions: it displays system status, provides commissioning information, enables maintenance operations, and facilitates troubleshooting. This single interface handles diverse tasks that would otherwise require multiple specialized tools or procedures.
3Manufacturing precision
If manual verification of connections is performed, then connection accuracy may improve, but the time required for commissioning increases
Solution Approach 1:
The system performs preliminary identification by automatically reading and storing data from function modules before the installer needs to make connections. This pre-prepared information is immediately available on the touchscreen, eliminating the need for time-consuming manual verification during the connection process.

AI summary
The invention relates to a method for supporting the implementation and/or maintenance of a central fire alarm system and/or fire extinguishing control centre (12), comprising a central control unit (30), several functional modules (14a-14g) and at least one data interface (36). A display unit (40) is connected to the central control unit (30) by means of the data interface (36) and an information mode, which can be activated and deactivated, is respectively associated with each functional module (14a-14g). Information is backed up for each functional module (14a-14g), and by activating the information mode of a functional module (14a-14g), the backed up information of the functional module (14s-14g) which has been activated, is represented on the display unit (40) or tablet (44). The invention further relates to a system for carrying out said method and a functional module.
