The LMSH-PS602 is a DLM-based shade room controller, which provides low voltage power and control for up two motorized shades. The controllers accept 120/277VAC input line voltage and are typically mounted in the ceiling to a four-square junction box. The controllers provide power and control for shades on the shade bus and connect and power switches on the shade In-Room-Bus (IRB). The DLM motorized room-based shade control system is easy to install and program. Motors and power supplies are connected using a four-wire shade bus with pre-configured cables and simple to configure bus system. The switches are connected using standard DLM in-room-bus (IRB) RJ45 cables for foolproof installation. The shade motors have a unique counter balanced design that is very quiet and saves energy. The patented motor design allows shades to be pulled into position from the hembar without damage to the motor or shades.
