A fire alarm system in which each device has a unique address, letting the panel identify exactly which detector, call point or interface generated an event.
Makes fault-finding far faster than conventional zones — always keep the device schedule current.
Drawings updated to show what was actually installed — positions, addresses, routes and interfaces — rather than the original design intent.
The UK code of practice for actuation of release mechanisms for doors — the fire-alarm-to-door-release interface and its categories of actuation.
A panel indication that the charging circuit or the batteries are outside limits — aged batteries, poor connections or a failed charger stage.
Check battery date codes and terminal voltage under load before condemning the charger.
The site-specific document mapping every alarm input to its required outputs (sounders, dampers, doors, plant, signalling); the reference for commissioning and testing.
An unversioned or missing matrix is a defect worth reporting in its own right.
Requiring two independent detectors in alarm before an output operates — standard practice ahead of suppression release.
The monitored interface releasing held-open fire doors on the mapped alarm condition; a released door must also close and latch fully to count.
Cause-and-effect logic requiring a second confirming trigger (same or second device) before a critical output such as plant shutdown or release operates.
Whether an electrically controlled lock releases (fail-safe) or stays locked (fail-secure) on power loss — chosen per door from escape and security requirements.
Escape routes generally demand fail-safe behaviour; confirm against the fire strategy.
A monitored input/output device connecting the fire system to other building systems — plant, dampers, lifts, security — under cause-and-effect control.
