Interactive Address Assignment for Fire Alarm Commissioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current alarm system commissioning processes are time-consuming and prone to errors due to the complexity of assigning device addresses, often resulting in duplicate or incorrect assignments, which can lead to safety issues in fire detection systems.
Innovation Solution
A graphical interface-based system that allows commissioning engineers to interactively assign device addresses by referencing a digital or physical building plan, using geo-magnetic or GPS positioning to accurately locate devices and prevent address duplication, thereby facilitating faster and more accurate commissioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual address assignment is used, then flexibility in address allocation is maintained, but commissioning time increases and errors increase
Solution Approach 1:
The system automatically assigns addresses to devices by having them communicate their status and location information to the central monitoring panel, eliminating the need for manual address assignment and reducing commissioning time while maintaining accuracy
Solution Approach 2:
The patent replaces manual mechanical address assignment processes with automated electronic communication between devices and the control panel, using digital signals to automatically establish device addresses and eliminate human error in the commissioning process
2Loss of time
If automated address assignment is implemented, then commissioning time is reduced, but system complexity increases
Solution Approach 1:
The central monitoring panel performs multiple functions including receiving device status signals, automatically determining device addresses, and managing device communication, thereby reducing commissioning time without requiring separate complex addressing hardware
Solution Approach 2:
The system creates a digital representation of device status and location information that is transmitted to the control panel, allowing automated address assignment based on copied data without requiring additional physical addressing components
3Reliability
If manual device identification is used, then address accuracy can be controlled, but error detection difficulty increases
Solution Approach 1:
The system automatically receives feedback from devices about their status and location, uses this information to assign addresses, and provides confirmation that addresses have been correctly assigned, making it easy to detect and correct errors in the commissioning process
Solution Approach 2:
The system performs preliminary actions by automatically determining device addresses before full system operation begins, allowing errors to be detected and corrected during the commissioning phase rather than after deployment

AI summary
The Commissioning phase is usually the most Time/Labor intensive phase in the Fire Safety System life cycle as the process involves referring to the Building floor plan document (as provided by the Installer) and creation of Areas/Zones and carefully assigning each fire device (viz. Smoke/Heat detectors, MCP etc.) to the corresponding zones in the Panel configuration software to configure the Fire Panel. The overall process easily spans for multiple days based on the Building network complexity. The present invention provides a system, apparatus and method for rapid commissioning by providing a graphical interface in which device addresses can be uniquely allocated using an interactive screen. This avoids double address faults which can be time consuming to identify and rectify. Geographic information of the devices can also be identified and incorporated using the interactive screen.
