Pseudo Non-Addressable Alarm System Automatic Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The installation and configuration of addressable fire alarm systems are time-consuming and expensive, making non-addressable systems more prevalent despite their operational advantages, due to the need for manual configuration of unique addresses, labels, and virtual notification appliance circuits.
Innovation Solution
A pseudo non-addressable alarm system utilizing addressable notification appliances and detectors, which allows for automatic or partially automatic grouping and labeling based on wiring, reducing the need for manual configuration and enabling installation similar to addressable systems with the use of 'T' taps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If addressable notification appliances are used with manual configuration of unique addresses and grouping, then operational efficiency and diagnostic capabilities are improved, but installation time and configuration complexity increase significantly
Solution Approach 1:
The system enables automatic self-configuration where notification appliances automatically receive and store unique addresses through the wiring infrastructure without requiring manual configuration. The system controller automatically discovers appliances on the circuit and assigns addresses, eliminating the need for installers to manually program each device while maintaining full addressable functionality for operational efficiency.
Solution Approach 2:
The system performs preliminary automatic address assignment and grouping configuration during installation setup, so that when the system goes into operation, all addressing and grouping is already complete. This preliminary automatic configuration eliminates the time-consuming manual setup phase while preserving the operational benefits of addressable systems.
2Reliability
If addressable notification appliances are used with manual configuration, then system diagnostics and control capabilities are improved, but device complexity and configuration cost increase
Solution Approach 1:
The notification appliances automatically receive their unique addresses and grouping information through the existing wiring infrastructure without requiring manual configuration. The system controller performs automatic device discovery and address assignment, reducing configuration complexity while maintaining the diagnostic and control capabilities of addressable systems.
Solution Approach 2:
Instead of manually configuring addresses and then grouping devices, the system inverts the traditional approach by automatically discovering appliances and assigning addresses through the wiring structure. This reversal eliminates manual configuration steps while preserving the reliability and diagnostic capabilities provided by unique addressing.
3Ease of manufacture
If non-addressable notification appliances are used, then installation cost is reduced, but operational flexibility and notification control are limited
Solution Approach 1:
The system uses standard non-addressable wiring infrastructure and notification appliances but adds automatic addressable functionality through the system controller. This allows the system to maintain the installation simplicity and cost benefits of non-addressable systems while gaining the operational flexibility and control capabilities of addressable systems through automatic device discovery and addressing.
Solution Approach 2:
The system controller acts as an intermediary that provides addressable control functionality to otherwise non-addressable notification appliances. By automatically assigning addresses and managing device grouping, the controller enables flexible notification control without requiring addressable appliances or manual configuration, thus maintaining installation simplicity while improving operational versatility.

AI summary
A pseudo non-addressable alarm system that uses addressable notification appliances and/or detectors is disclosed. In one aspect, the addressable notification appliances and/or detectors may be entirely automatically (or partially automatically) grouped. One manner of automatic grouping is to use the wiring of the pseudo non-addressable system in order to automatically form the groupings of notification applications, such as grouping the notification appliances based on the signal line circuit to which they are connected. In another aspect, labels for the notification appliances and/or detectors in the pseudo non-addressable system may be entirely automatically (or partially automatically) generated. The labels may be automatically generated based on wiring of the pseudo non-addressable system and/or based on grouping information (such as grouping based on the particular signal line circuit to which the notification appliance is connected).
