X-10 is a very safe and inexpensive control device that allows us to control appliances, lights, fans, radios and with extra equipment, TVs telephones, VCRs DVDs, etc. over existing power (wiring) lines in house.
Advantages of using an X-10 system over an expensive off the shelf ready to use unit is that it is inexpensive, uses existing home wiring, works with existing home environmental control units, and it is safely and easily adapted.
Disadvantages are that it requires a separate controller for each unit and can cause interference with nearby X-10 systems with similar settings. Each appliance is only electronically "unplugged or re-plugged" to turn the device "on" or "off" with this system. For example, a ceiling fan can be turned on and off, but the speed of the fan cannot be adjusted with a simple X-10 device.
Anyone who has a need to turn these devices on and off from a single location. This may be someone who is confined to a bed or those who have fine motor problems, poor eyesight, ambulation difficulties, etc. X-10 Systems can also be used for fall prevention, adaptation of nurse call lights, an incontinence alarm, a wandering away alarm, etc.
X10 uses house code letters (A-P) and numbers (1-16) to differentiate from other systems. This way two or more systems can exist on the same rehab unit or home without interfering with each other. The simplest system will consist of one transmitter module and one transceiver which is where the appliance is plugged in. There are several different types of control modules that are used for various devices.
Each appliance needs to be controlled by a separate device (a module). Two or more modules including a transmitter and receiver module can make up a X10 system (can be many modules in the same system)
To discriminate between different X10 modules and between different X10 systems X10 uses house codes and unit numbers to tell the modules an entire systems apart. This way two separate systems can exist on the same rehab unit or same apartment complex without interference from each other.
