Spirit LT Series™ ALCMS

Airfield Lighting Control & Monitoring System (ALCMS)

The Spirit LT Series™ ALCMS brings the latest in PLC and touchscreen technology to small airports. Designed as a replacement for L-821 push button control panels, this L-890 certified control system is a scaled down version of the industry leading Spirit Series™ ALCMS. This cost effective ALCMS is a result of over 20 years of control system experience.

System Application

The Spirit LT Series™ ALCMS is a modular, expandable system designed for general aviation and small regional airports. Having most of the basic control capabilities of the Spirit Series™ALCMS provides airports with high-end flexibility without the additional cost and complexity associated with features that are not required at smaller airports. System applications include:

• Control and monitoring of runway and approach lighting, taxiway lighting, rotating beacon, wind cone, apron floodlighting.
• Monitoring of diesel-generator and automatic transfer systems.

Standards Compliance

• FAA Advisory Circular 150/5345-56, Spec L-890 L890-X-Y Classification types where:

• FAA Advisory Circular 150/5340-30, Design and Installation Details for Airport Visual Aids.
• ICAO Annex 14, Volume 1, Aerodrome Design and Operations.
• ICAO Aerodrome Design Manual Doc 9157, Part 5.
• Transport Canada Aerodrome Standards and Recommended Practices, Volume 1, TP-312E.
• Canadian Department of National Defence Standards.

Features and Capabilities

• On/off and brightness contol buttons are provided for each airfield lighting circuit or system (runway, taxiway, approach, etc.)
• Actual status of circuits can be displayed with current present monitoring option.
• Control of multiple regulators, circuit selectors, and other equipment in the electrical vault and control tower or Flight Service Station (FSS).
• Control of the airfield lighting from the tower or FSS with backup from the electrical vault.
• 100MB Ethernet communication between locations using fiber optic cables, radio or telephone lines.
• Photocell and air-to-ground control are provided for unattended operation.
• Adjustable soft-start feature extends lamp life.
• Adjustable on-delay feature minimizes in-rush when operating on backup diesel generator.
• Utilities include lock screen, touch-screen calibration, and background dimming.
• Set-up, layout and configuration of the system can be done by airport maintenance staff, systems integrators, consultants or contractors. No programming knowledge is required.
• Configuration menus and displays are accessible only to personnel authorized by the airport.

Technology Benefits

• Reliability, simplicity and longevity of a PLC based system.
• Critical control logic provided by PLCs designed for twenty year life and 24/7 operation.
• Embedded industrial controllers with no hard drives, fans or moving parts provide critical touchscreen operator interface graphics.
• Off-the-shelf hardware and software ensures longterm support is always available. The airport is protected from any unforeseen supplier changes.
• 100MB Ethernet communication network with support for point-to-point fiber, wireless radio, CAT5 cables and DSL capable telephone lines.
• Remote access via high-speed internet or dial-up modem provides the ability to remotely upgrade the system or assist maintenance personnel.
