Tiny, Wireless Motion Sensors! Imagine having your lights turn on automatically the instant you step into the room! The RMS18 Occupancy Sensors are small, sleek and very powerful! They supercharge any home by removing the need for switches and buttons. You can now make things happen as soon as you walk in a room! The RMS18 sends wireless Radio Frequency (RF) signals to an X10 Transceiver or any X10 security system base receiver. The Transceiver receives the signals from the Motion Sensor and passes them onto your house wiring. These signals are then received by X10 lamp, appliance, or wall switch modules to control lights (or appliances) around the home. If you set the RMS18 to a unique code (House Code A and Unit Code 1), then walk into the room where the sensor is located, a lamp module set to "A1" will turn on. As long as you keep moving, the light will stay on, and when you stop moving, the light turns off after the amount of time you select. The signals transmitted onto your house wiring can also be received by the two-way Computer Interface to initiate macros. The Computer Interface then performs a sequence of events that you've set it up to do
