Wireless Fire Alarm Configuration via Handheld Intermediary
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current fire alarm systems require technicians to physically return to the fire alarm control panel for configuration and information changes, making it difficult to manage and configure devices, especially in large systems, as configuration tasks can only be performed at the central control panel.
Innovation Solution
A fire alarm control panel with wireless communication capabilities that allows configuration through a handheld device, enabling remote access and updating of configuration information for fire alarm system devices, including notification appliances and detectors, using a wireless interface and memory for storing and retrieving configuration data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If configuration is performed at the central control panel, then system control and monitoring are centralized, but technician mobility is limited and configuration efficiency decreases
Solution Approach 1:
A wireless handheld device serves as an intermediary between the technician and the central control panel. The handheld device communicates wirelessly with the FACP, allowing technicians to configure fire alarm devices remotely without physically returning to the control panel. This intermediary enables mobile configuration while maintaining centralized system control.
2Reliability
If all configuration operations are performed at the FACP, then system integrity is maintained, but configuration complexity and difficulty increase for field technicians
Solution Approach 1:
The handheld device acts as an intermediary that simplifies the configuration interface for field technicians while maintaining secure communication with the FACP. It provides a user-friendly interface for device configuration, address assignment, and label customization, reducing the complexity of configuration tasks without compromising system integrity.
Solution Approach 2:
The handheld device creates a portable copy of the configuration interface and communication protocols normally available only at the FACP. This allows technicians to perform configuration operations remotely by copying the essential functionality to a mobile device, reducing the need for complex wired connections and specialized equipment at the control panel.
3Productivity
If technicians must return to the control panel for device configuration, then centralized monitoring is maintained, but productivity and response time decrease
Solution Approach 1:
The wireless handheld device enables technicians to configure fire alarm devices directly at the device location without returning to the control panel. This intermediary solution maintains centralized monitoring through wireless communication with the FACP while dramatically improving field accessibility and configuration speed.
Solution Approach 2:
The system transitions from a two-dimensional configuration process (technician at control panel) to a three-dimensional process by adding the wireless communication dimension. This allows configuration operations to occur in multiple spatial locations simultaneously, with the handheld device serving as a mobile configuration station that communicates with both the FACP and field devices.
Data Source
AI summary
A method and system for configured one or more fire alarm system devices in a fire alarm system are disclosed. The fire alarm system includes the fire alarm system devices, a fire alarm panel, and a wireless handheld device. The fire alarm system devices communicate with the fire alarm panel via a first communications interface (such as a wired communications interface), and the wireless handheld device communicates with the fire alarm panel via a second communications interface (such as a wireless communications interface). In operation, the fire alarm control panel receives an indication from one of the fire alarm system devices of a user input. In response, the fire alarm panel sends a communication (such as a form) to the wireless handheld device. In response to the communication, the wireless handheld device sends a response to the fire alarm control panel (such as including information in the form). The fire alarm panel may then update its memory with the information sent from the wireless handheld device in order to control the operation of the fire alarm system device.
