Solution Overview

Problem

Existing emergency voice evacuation systems lack addressable paging capabilities, making it impractical to broadcast messages across large areas with multiple zones, as they typically broadcast messages over the entire system without the ability to selectively target specific zones.

Innovation Solution

A supervised paging, messaging, and emergency voice evacuation system that includes a telephone zone controller and addressable paging splitter, capable of routing and playing audio in selectable zones, allowing for Class A and Class B mode operations, enabling zone-specific messaging and background music control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If paging is implemented over the entire emergency voice evacuation system, then the paging message can be broadcast across all zones, but it becomes impractical for large areas with many zones and lacks addressability

Engineering Contradiction:
Improvepaging coverageVSAvoidsystem addressability
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system divides the emergency voice evacuation network into multiple addressable zones using zone controllers and paging splitters. Each zone can be independently addressed and controlled, allowing selective paging in specific areas rather than broadcasting to the entire system. This segmentation enables practical implementation for large facilities with numerous zones while maintaining system manageability.

Inventive Principle:
Principle #1Segmentation

2Adaptability or versatility

If the system provides selective zone addressing capability, then paging can be targeted to specific zones, but the system complexity increases with additional controllers and splitters

Engineering Contradiction:
Improvezone addressing capabilityVSAvoidnumber of components
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The zone controllers and paging splitters are designed as multi-functional devices that can handle both emergency voice evacuation and selective paging operations. These components serve multiple purposes: emergency notification, selective paging, background music playback, and system supervision. This multi-functionality reduces the need for separate dedicated equipment for each function, thereby limiting the increase in system complexity while providing comprehensive zone addressing capabilities.

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If the system supports both emergency voice evacuation and selective paging, then functionality is enhanced, but the device complexity and control requirements increase

Engineering Contradiction:
Improvesystem functionalityVSAvoidcontrol mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system merges emergency voice evacuation control and selective paging control into a unified architecture using the same zone controllers, paging splitters, and notification appliances. The control mechanisms for both functions are integrated, allowing a single control interface to manage both emergency evacuation and selective paging operations. This consolidation enhances functionality while limiting the increase in control complexity compared to having separate independent systems.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The present invention generally discloses a supervised paging, messaging background music and emergency voice evacuation system. In one embodiment, the system comprises at least one telephone zone controller and at least one telephone zone paging speaker splitter or addressable paging splitter. Specifically, telephone zone controller acts as a controlling authority for the routing and playback of audio in selectable zones. In cooperation with the telephone zone controller, the telephone zone paging speaker splitter is an addressable device that is capable of splitting an audio signal in different manners, e.g., in Class A mode or in Class B mode. The present system provides addressable functions that are not found in existing supervised paging, messaging background music and emergency voice evacuation system.
