The Lilley & Gillie IWAS P1250 is an integrated marine wind alarm system designed by John Lilley & Gillie Ltd. to deliver real-time monitoring of wind speed and direction on commercial vessel bridges, offshore platforms, helidecks, and workboats. Engineered to enhance operational safety during cargo handling, crane operations, helicopter landings, and rough-weather navigation, the P1250 continuously processes anemometer sensor data to trigger immediate warnings when wind parameters breach safe operational limits.

Featuring a clear, high-contrast digital display and intuitive control interface, the IWAS P1250 allows navigation officers to set custom high-wind speed thresholds and directional alarm zones. The unit receives digital NMEA 0183 wind sentences from standard marine anemometers and pulse sensors, integrating seamlessly into bridge console networks and centralized alarm systems.

Key Features:
• High-Wind Speed & Direction Alarms: User-programmable alarm limit thresholds for high wind speed gusts and unsafe wind angles.
• Real-Time Digital Display: Bright, high-visibility digital readouts for wind speed (knots, m/s, or Beaufort scale) and wind direction.
• Universal NMEA 0183 Compatibility: Processes standard IEC 61162-1 wind data sentences ($WIMWV, $WIMWD, $WIVWT).
• Dual Audible & Visual Warning: High-intensity LED warning indicators paired with an audible buzzer for instant alert notification.
• External Relay Outputs: Potential-free relay contacts enable connection to external alarm sirens, VDR data loggers, or bridge alarm panels.
• Night-Watch Dimming: Front-panel variable backlighting control for low-glare operation during night watches.
