Spacesaver’s Eclipse Powered System of high-density mobile storage (HDMS) provides menu-based configurability, modular design to allow for future upgrades, and a wide array of safety and security options. With the redesigned Zero Force Sensor system, a series of infrared photoelectric beams detect when a person or object is present in an open aisle. Carriage movement stops until the person exits or the system is reset. Should a power outage occur, a backup-power option automatically switches to batteries. The Eclipse Powered System also offers lighting options, including energy-saving aisle lighting that illuminates only the occupied aisle and turns off lights automatically after a set period of inactivity.
