Loading Dock Safety continues to be a major challenge for most companies. Whether your business is large or small, manufacturing or distribution, accidents are real and can be fatal.Safety Signal uses the universal signal protocol utilizing Red and Green LED Lights. It is a simple, yet effective means to provide safety at your loading dock door. Saves Time & Money Safety Signal automates your loading dock by providing a clear, distinct communication signal to your loading dock workers and truck drivers. It eliminates the need for manual communication systems that are often unreliable. Safety Signal offers amicroprocessor based control panel, convergent photo eye and LED light signals to ensure reliability and productivity with no maintenance. With optional interlocks for your dock light, fan, and leveler, Safety Signal automates your loading dock area to improve productivity and reduce energy consumption. Safety Is A Major Concern Safety Signal goes beyond ordinary communication packages by using 180 LED lights on the inside control panel to ensure dock workers are aware of an unsafe situation at the dock. The outside light box not only uses high intensity LED lights but each circuit is designed to handle two LED's. Therefore, if one LED were to fail, the light output is more than enough to generate a clear, distinct signal. The outside box has a patented light process that channels the flashing red light signal directly into the mirror of the truck so the light can't be ignored. This patented light process also reduces communication error to other truck drivers at nearby loading docks and protects the light signal from interference caused by direct sunlight. Safety Signal uses a convergent photo eye mounted above the door in lieu of whisker switches that are old technology and unreliable. Saves Energy...Go Green Safety Signal's interlocks are not only a great safety feature for the dock worker, but they also take care of turning equipment on/off saving you costly energy consumption. The interlock is engaged by the photo eye. When the door opens/closes and the photo is engaged/disengaged, the interlock turns the light and fan on/off automatically. Depending on the model, there can be two outlets on the bottom of the inside control unit to plug in a fan and light. The leveler can also be interlocked with the Safety Signal so that it can only be turned on after the door has been opened. With LED's used in the inside and outside boxes, Safety Signal is not only energy efficient it is also maintenance friendly.
