Keedian operations · Standard procedure

Water / air pressure drift.

Where the optional read-only pressure transducer is installed, the sprinkler-riser / fire-pump water pressure (or, on a dry system, the supervisory air pressure) is out of band or drifting toward the panel's supervisory threshold — an early sign of a valve creeping shut, supply degradation, a small leak, or jockey-pump short-cycling, caught before the panel's single-threshold switch trips.

Trigger
pressure out of band OR pressure trending toward supervisory_threshold (raises pressure drift; requires optional transducer)

Operational continuity
Preconditions
Requires the optional read-only pressure transducer installed on the sprinkler riser / fire-pump discharge (and, on a dry system, the supervisory air line), tapped on an existing gauge port by / with the licensed fire contractor. In-band range and drift rate are configured per building against the design pressure.
Human role
Primary — Keedian reads the pressure trend and raises the drift alarm; investigation and correction are the licensed provider's. Operators refer the trend with the reading. This alarm exists only where the optional transducer is installed.
Action plan
(1) Confirm the reading is a sustained out-of-band value or a genuine downward trend, not a momentary transient (a test, a surge). (2) Refer the trend to the licensed provider with the reading and the rate, framed as an early warning before a supervisory trip. (3) Keep the pressure trend on record so a slow, chronic decline is visible over time.
Escalation
(1) Pressure crossing the supervisory threshold → this is now a panel supervisory condition; handle it as the panel fault signal, out of cycle. (2) A persistent downward trend that a provider visit does not resolve → flag the supply / valve for a deeper investigation.
Prevention
(1) Set the in-band range and drift rate against the system's design pressure per building. (2) Trend pressure continuously so slow drift is caught well before the single-threshold supervisory switch would trip.
