Case Studies
From Fire-Door Activity to Operational Evidence
EdgeGuard PulseNet deployment at Vivacity Stage 1, Lidcombe NSW
Vivacity Stage 1 required a practical way to improve visibility across multiple fire-door locations without relying on Wi-Fi at each door or replacing existing building systems. Synexon designed and deployed PulseNet as a physical monitoring layer integrated with the EdgeGuard governance platform. Fifteen field nodes now provide structured door-event evidence through a dedicated local receiver and Gateway/Controller, with validated events delivered to the site's EdgeGuard platform for authorised review.
The Challenge
Fire doors are distributed across multiple parts of the property and are not continuously visible to building management. Traditional physical inspections remain important, but they do not provide continuous evidence of what happens between inspections. The project required a system capable of monitoring distributed door activity, operating without Wi-Fi at every fire door, retaining useful event evidence, identifying stale or missing communications, giving site management one browser-based operational view, operating alongside existing building and security infrastructure, and supporting future governance and reporting workflows.
A Local-First Monitoring Architecture
Synexon deployed a purpose-built PulseNet field network integrated with EdgeGuard. Each monitored fire door is equipped with a dedicated transmitter node. Door activity is communicated over a low-power long-range wireless path to the site's receiver. A Synexon Gateway/Controller validates and forwards PulseNet event data to the local EdgeGuard production environment. The result is a local-first architecture where critical operational monitoring remains under site control while authorised users access the evidence through EdgeGuard.

Evidence, Not Just Alerts
PulseNet does more than display whether a door was last observed open or closed. EdgeGuard stores operational evidence including door state, local alarm state, event sequencing, event time, received time, signal evidence for diagnostics, and freshness classification (current, stale, or offline based on the age of the latest received evidence), alongside a searchable record of historical activity.
The displayed state represents the latest successfully received device evidence. It should not be described as independently proving the current physical position of a door.
The Result
The completed Vivacity deployment includes 15 commissioned fire-door monitoring nodes connected through the site's dedicated PulseNet receiver and Gateway/Controller architecture. Site management now has a central operational view of PulseNet evidence rather than relying only on isolated physical observations. The deployment establishes a practical foundation for continuous operational visibility, structured incident evidence, event-history review, communication-freshness monitoring, facilities-management governance, and future integration with additional EdgeGuard capabilities.

Physical Monitoring Connected to Governance
The Vivacity project demonstrates the wider EdgeGuard model. A physical event at a building asset can become structured, timestamped evidence rather than remaining an isolated alarm or manual observation. This allows EdgeGuard to act as the governance layer between physical building events and the people responsible for reviewing, responding to, and reporting operational risk. The same architecture can be extended to other monitored assets, sites, and facilities-management obligations without requiring organisations to replace all of their existing operational systems.
Designed for Operational Resilience
The production EdgeGuard environment operates locally at the site, with controlled runtime recovery, protected production configuration, and a dedicated Gateway/Controller architecture. Synexon can also securely support the site through a controlled remote-service pathway without making the EdgeGuard application publicly accessible on the internet. This reflects Synexon's local-first design philosophy: critical building operations should remain under local control.
Need Better Visibility Across Critical Building Assets?
Synexon EdgeGuard connects physical building events with structured operational evidence, governance, and reporting. Whether the requirement involves fire doors, plant, access events, or other operational assets, Synexon can design a local-first monitoring architecture around the site and its existing systems.
