IDSL-NAi
SeaMark ID Sign Light
Designed for the uniform illumination of ID signs up to 1500 mm high by 2200 wide to satisfy IALA recommendation O-139. The rugged stainless-steel design integrates the optical head and mechanical support.
NAi interface – Communication and power are provided through the NAi network.
LED technology – Using the highest quality LED technology, the LED 160 provides the highest light output with low power consumption.
Low maintenance – With simple interfaces, LED technology and remote monitoring, the Seamark Marine Lantern is extremely low maintenance.
Smart photocell – A smart photocell ensures accurate day to night switching by distinguishing between the light produced by the ID Sign Light and ambient light. The small photocell also functions as an autonomous fall-back solution should communication on the bus be interrupted. The light is then switched on when the ambient light level falls below a minimum, pre-set, configurable level.
