This battery-powered Ice Guardian Sign / Ice Detector LED Sign replaces older mechanical ice alert signs, which require manual intervention.
It is a solid state device with no moving parts and LEDs to provide a high visual impact. The sign incorporates an ISO standard ice crystal warning logo with ultra-bright blue LEDs located at the 6 points. The LEDs flash when the air temperature approaches freezing.
The sign can be fixed to a pole or post. The sign includes batteries that last up to 3 years before replacing.
The sign is perfect for organisations who want to minimise the risk of ice-related accidents, and can be used for pedestrians and drivers. The Ice Guardian Sign / Ice Detector LED Sign is generally used for off-highway applications including: quarry sites, campuses, car parks, ports etc.
How It Works
The sign incorporates a circuit board that is powered directly from 6 AA alkaline batteries in a rear compartment protected with a weather-proof bung. A sensor on the circuit board triggers a flashing sequence when the temperature reaches 3 degrees Celsius.
The LEDs flash for 30 mS every 2 seconds and power is minimised by switching the PIC chip to sleep mode when not required. The combined effect of these is to give the sign a two to three year life per set of batteries. Batteries can be changed easily when required.
Ice Guardian Sign / Ice Detector LED Sign has no moving parts and is sealed to the weather. It is very reliable, requiring minimal maintenance other than just a battery change every few years.
The LED's are visible in daylight and have a wide angle of inclusion.
