Measured at the panel and at points around the loop, the loop voltage shows whether devices are actually receiving what the panel thinks it is delivering. A healthy loop shows close to the panel's output at the far end; a significant drop points to high-resistance joints, undersized or damaged cable, or an overloaded loop. Compare readings against the manufacturer's stated limits for the protocol, and record where you measured — a voltage figure without a location is useless on the next visit. Standards are referenced for orientation only — always confirm requirements against the current edition of the applicable standard, the site's fire strategy and manufacturer documentation.

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.
