Engineer Use Guidelines

These guidelines set out how to use Incognito Fire & Security responsibly. The service is a professional aid for competent fire and security engineers — it supports your judgement, it does not replace it.

Treat all guidance here as the lowest tier of authority. Always defer, in order, to: the manufacturer's manual for the exact panel and firmware; BS 5839-1 and other applicable standards; and the site-specific cause & effect and risk assessment.

• Confirm any specific value, code meaning, or procedure against the manufacturer manual.
• Treat fault-database records marked "Provisional" as unverified starting points.
• Never rely on the assistant for engineer access codes, bypass steps, or anything that defeats a life-safety function — these are not provided and must not be sought.

For suppression, smoke control, AOVs, lifts, evacuation interfaces, door release/hold-open, plant shutdown, monitoring/ARC, or multiple simultaneous faults, obtain site-specific verification and involve a competent person before acting. These queries may be logged for safety and quality purposes.

Before any testing that could generate signals, place the Alarm Receiving Centre (ARC)/monitoring "on test", and return it "off test" afterwards — and confirm with the ARC.

If you spot an inaccurate record or a broken resource link, please report it so we can correct it. Accurate, verified data protects everyone.
