Guidance only. This assistant provides general guidance only and is the lowest tier of authority. Always defer, in order, to: the manufacturer's manual, then BS 5839-1, then the site-specific cause & effect and risk assessment — before this tool. It does not provide engineer access codes, bypass instructions, or unverified procedures. Verify all specifics against the manufacturer manual for your exact panel and firmware. Place the alarm receiving centre (ARC)/monitoring “on test” before testing and “off test” after. For high-risk systems (suppression, smoke control, AOV, lifts, evacuation interfaces, door release, plant shutdown, monitoring) obtain site-specific verification. You remain responsible for safe working and compliance.
