The UMA series are plug-in modules designed to control 120VAC appliances, fan/pump motors and fluorescent lights based on lighting scene-link commands received over the power line. The lighting scene commands are communicated using highly-reliable Universal Powerline Bus (UPB) technology. UPB devices such as switches, multi-button controllers and schedulers are easily integrated in to a new home or can replace switches and timers in an existing home. UPB technology requires no new or special wiring, it provides a flexible, low-costs alternative to hardwired or RF home lighting and automation strategies.
UMA modules deliver on/off control for appliances, fan/pump motors and fluorescent lights (see model UML, dimmer modules for incandescent lamp control). Installation is simple: the module is plugged into a standard 120 VAC outlet and the appliance or light to be controlled is plugged into the bottom of the module. The connected appliance can be manually controlled by a UPB switch or multi-button controller, or automatically with a scheduler (model UCS-01), I/O module (model UMI) or with any PC / security / home automation controller that provides a UPB serial driver software option.
The timer feature of the UMA-20-W automatically turns off the controlled outlet after a preset period of: 1, 5, or 30 seconds; 1, 2, 4, 10, 20, 30, 40, or 50 minutes; 1,2, 3, or 4 hours. The timer can be disabled so the UMA-20-W functions like a standard appliance module (no timer function).
A UPB switch, such as the US2-40, can command any of the UMA-20- W timer functions via lighting scene/link commands to enable any selection of the timed off options.
