Range: 3 - 7NM (daytime) / 20 - 27NM (nighttime) @ 0.74T
Ideal for: port & harbour range light applications
The FA-14 range light is designed to provide a high peak intensity output for long range nighttime and daytime signaling applications. It provides reliable output under varying environmental conditions, adaptability to different signaling requirements including wireless synchronization, simple logistics, and long service life with reduced spare parts requirements.
With the increase in development in port areas, it is becoming increasingly more difficult to distinguish the leading lights from the background lighting. Increasing the candlepower of the light and rhythmically flashing the lights give some improvement but the random nature of the flashing limits effectiveness. Synchronization of the flashing leading lights is known to greatly increase the conspicuity of the lights but it is costly to have a hardwire synchronization connection between the two lights.
A two station range makes it possible for the mariner to navigate the center of a restricted channel. The lights of each station, front and rear, are aligned when the ship is on the channel's centerline. The lights separate when the ship drifts to either side. This feature gives the pilot a “feel” for his position off the range since he can tell the direction and degree of drift. Course correction can be evaluated immediately by whether the lights begin to "close" or continue to "open."
However, with a single station polychrome range, the pilot knows only if he is in the center of the channel or to one side or the other. There is no indication of degree of navigation error. Also, he’s unable to determine if the ship's position is improving or worsening.

Optional Accessories:
*Note: Also available as a special feature is reverse photocell action. The photo sensor on the lantern will detect the day/night transition and can be loaded with a special “optional” firmware to change the intensity of the light so it will produce, for example 4,600 cd during the day (for a 1NM range), switching at night to a low intensity of 100 cd for a 5NM range. The maximum intensity to be used during the day time is of course limited by the lantern capacities.
