Continuous Fire Door Compliance
The Golden Thread
Fire Door Asset Register

The world’s first real-time fire door monitoring and compliance device. Every fire door now creates its own continuous digital record. Your entire fire door portfolio in one live asset register.

For the first time, fire door compliance no longer has to stop when an inspection ends. Parilon continuously monitors the activity and behaviour of every connected fire door, alerting the responsible person when the data identifies warning signs or a potential issue requiring investigation. Measure. Interpret. Act.

Parilon automatically records monitoring data, alerts, inspections, maintenance and remedial activity against the individual door. The result is a live, date and time-stamped history, giving Responsible Persons clear, traceable evidence that strengthens their Golden Thread.

Parilon replaces static spreadsheets and disconnected reports with a live view of every connected fire door you manage. See current compliance health, identify doors requiring attention and track every action through the same platform.

Three essential capabilities. One connected fire door compliance system

The problem

75%

of UK fire doors fail inspection.

A damaged fire door, a failed closer or a door left open can compromise the protection it was installed to provide. Without continuous visibility, that failure can remain hidden until the next inspection.

Source: FDIS inspection data, 2021 — based on 100,000+ UK fire door inspections.

There is no live visibility between inspections.

Building owners invest in critical fire-safety assets, then lose sight of their condition until the next inspection. By the time a problem is discovered, protection may already be compromised and a minor repair may have become a costly replacement.

Lives relying on protection that may no longer be there

If a fire door fails between inspections, the people behind it could be relying on a life-safety system that is no longer working as intended.

Fire-door safety is an ongoing legal responsibility

Responsible Persons are legally accountable for ensuring fire doors are properly maintained, in efficient working order and in good repair. The inspection ends. The legal responsibility does not.

Buildings left exposed

When a fire door is damaged, held open or fails to close correctly, compartmentation can be compromised, giving fire and smoke a route through the building.

Minor issues become major costs

Without early warning, a simple adjustment can develop into extensive remediation, or leave an otherwise serviceable fire door requiring premature replacement.

Paper checklists don’t keep buildings safe.

The shift

What is continuous fire door compliance?

Continuous fire door compliance is the practice of monitoring fire doors in real time with connected sensors, rather than assessing them periodically by hand. Every door reports its own condition — closure, hold-open events, hardware movement, damage — and every event is logged as timestamped, auditable evidence. Compliance stops being a date in a calendar and becomes a live state you can prove.

What the industry has relied on

  • ×Door condition only known when inspected
  • ×Problems hidden between scheduled checks
  • ×Inspection, maintenance and remedial records disconnected
  • ×Action beginning after failure is discovered
  • ×Minor issues becoming costly repairs and premature replacements

What Parilon makes possible

  • ✓Continuous visibility between scheduled inspections
  • ✓Early warnings when a door may require investigation
  • ✓A live asset register for every connected door
  • ✓Automatic records supporting the Golden Thread
  • ✓Earlier intervention protecting lives, buildings and budgets
The connected system

Real-time monitoring through the Smart Fire Door Device. Live intelligence through Sensorite.

The Smart Fire Door Device continuously monitors activity and behaviour at the door. That information is sent directly to Sensorite, where it is analysed and connected to the door’s live digital asset record. When the data identifies unusual behaviour, a developing pattern or a potential concern, Sensorite identifies the affected door, alerts the responsible team and records every action that follows.

Smart Fire Door Device

A retrofit sensor that fits to the fire doors you already have. It watches every closure, every hold-open and every movement in the hardware — all day, every day.

  • Fitted in minutes. No new doors, no rewiring, no disruption to residents.

  • Certification preserved. Nothing about the door’s rating changes.

  • Battery powered, long-life. Reports continuously without a site visit.

How Parilon works

Measure. Interpret. Act.

Every door monitored. Every warning sign understood. Every concern directed to the people who can act.

See the full journey
  1. 01

    Measure

    The Smart Fire Door Device continuously measures the activity and behaviour of every connected fire door.

  2. 02

    Interpret

    Sensorite analyses the data to identify unusual activity, developing patterns and warning signs that may require investigation.

  3. 03

    Act

    The responsible team is alerted, allowing them to investigate earlier and record every action against the door.

Competence establishes the baseline. Parilon monitors what happens next.

A competent fire-door professional uses their skills, knowledge, experience and behaviours to assess the door and establish its recorded condition. Parilon then monitors the connected fire door continuously, identifying changes that may require that professional judgement to be applied again.

Retirement Living

Residents who cannot self-evacuate, and doors propped open for reasons nobody could reasonably object to.

Retirement Living

Student Accommodation

High density, high churn, twenty-four hour occupancy and a wedging culture no inspection cycle will ever catch.
