Alarm System Conditional State Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing alarm systems in facilities often trigger unnecessary evacuations due to false alarms, which can lead to significant losses in time and productivity, especially in larger facilities where verifying the nature of the alarm is difficult and requires multiple users.
Innovation Solution
A mobile device-based system that allows users to acknowledge and verify detected events, preventing alarms during false events and ensuring timely notification during true events, by transitioning the alarm system through conditional and alarm states with timed acknowledgments and confirmations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If alarm systems trigger immediately upon detecting an event, then response time is improved, but false alarms cause unnecessary evacuations and productivity losses
Solution Approach 1:
The system performs preliminary verification actions before triggering the alarm. When an event is detected, the system first transitions to a conditional state and sends a notification to a remote computing device for verification. Only after confirmation that the event is genuine does the system transition to the alarm state and trigger evacuations, thus preventing false alarms while maintaining rapid response capability.
2Reliability
If multiple users are required to verify alarm events, then reliability is improved, but device complexity and operational difficulty increase
Solution Approach 1:
The system enables single-user verification through a mobile device interface. The remote computing device receives the conditional alarm notification and allows a single user to verify the event authenticity and confirm whether to trigger the alarm. This simplifies the operational process while maintaining reliability through proper verification procedures.
3Reliability
If alarm verification requires multiple users, then false alarm prevention is improved, but time loss and productivity reduction increase
Solution Approach 1:
The system performs preliminary verification through a streamlined single-user process before triggering the alarm. The remote computing device enables quick verification of the detected event, allowing the system to determine within a short time frame whether the event is genuine. This reduces verification time while still preventing false alarms through proper verification protocols.
4Reliability
If the alarm system transitions through conditional states with timed acknowledgments, then false alarm prevention is improved, but system complexity increases
Solution Approach 1:
The system dynamically transitions between operational states based on event verification. It moves from a normal state to a conditional state upon event detection, then to either an alarm state or back to normal state based on verification results. This dynamic state management enables sophisticated verification logic while maintaining clear, manageable system behavior through well-defined state transitions.

AI summary
Devices, systems, and methods for alarm system states are described herein. In some examples, one or more embodiments include a mobile device comprising a memory and a processor to execute instructions stored in the memory to receive a notification from a remote computing device that an event device in an alarm system has detected an event, where in response to the alarm system detecting the event, the alarm system is in a conditional state, acknowledge the event to cause the alarm system to remain in the conditional state, and transmit a signal to the remote computing device indicating whether the event is a true event or a false event, the mobile device further including a user interface configured to display the notification.
