In Archives II, the mobile system's electric controls are tied into the building management control system, and storage modules in restricted areas require security cards and access codes to prevent unauthorized use. As discussed earlier, photoelectric safety devices available on electric systems offer the best protection and least potential for damage to an object moving in an aisle. A moving carriage does not have to come into contact with the object in order to be stopped. Protecting the Systems Most high-density mobile storage systems are built to last for decades of use. However, the best protected systems are those whose movement is controlled, either by trained operators or electronic controls.
Security often goes hand in hand with protecting the systems from abuse.
A person going through that much security probably will treat the system with care. Also, systems can be equipped with an anti-tip device that will help carriages stand up to earthquakes or a prankster climbing on the shelves. Such evaluation is often best done by a trained mobile storage designer and installer. These professionals are experienced in addressing all the considerations, and can offer site visits to installations facing similar challenges. These evaluations and design recommendations are normally free as part of a professional consultation.
