Constant Current Regulators, ALCMS & A-SMGCS Control installations at King Abdulaziz International Airport (JED)

The control-and-power brain of the airfield lighting system: Constant Current Regulators (CCRs, typically 2.5–30 kW, FAA L-828/L-829) that drive each series loop at a regulated current, plus the Airfield Lighting Control & Monitoring System (ALCMS) and individual light control & monitoring (ILCMS) that let the tower switch, dim and fault-locate every fixture. The same cluster covers FAA L-890 runway-incursion alerting, stop-bar/lead-on logic and A-SMGCS integration with the tower automation platform. Procurement here is engineering-led — specified by loop count, redundancy, monitoring granularity and CAT II/III low-visibility certification — and is usually bought alongside, but separately from, the fixtures themselves.

Jeddah is the gateway to Makkah — and few airports carry such spiritual and logistical weight in a single footprint. Its Hajj Terminal, a Skidmore Owings & Merrill marvel of tented fibreglass, has moved pilgrims for four decades while the new Terminal 1 by HOK now handles Saudia's widebody flows. 2024 traffic climbed to 49.1 million as the Kingdom chases a goal of 150 million pilgrims and tourists a year by 2030.
