The I.S.I. Demonstration Smart Home
A DISCRIPTION OF EQUIPMENT AND FUNCTIONS
The heart of our “Smart Home” is the system by AMXâ Corporation (formerly Panjaâ Corporation). We have an older system called the PHAST Landmark system. The newer system is the NetLinx system. The major difference between the two systems is that the Landmark system can only be accessed remotely via telephone whereas the NetLinx system “sits” on the internet and is accessible by any computer connected to the web (securely, of course, via a firewall, username and password).
The Landmark system in the I.S.I. home provides the overall control for all other systems on the property and directs the whole house audio/visual system. The system consists of an IBM PC, a Card Frame (PLB-CF10) that contains the system main processing unit (MPU) and other system cards (IR Out, Relay, Contact, DTMF, etc.). The system also includes a Hub Box (PLB-HUB) (which contains a Microphone Hub Card), a 16 channel Audio Switcher (PLB-AS16), (2) 8 channel Audio Amplifiers (PLB-AMP8) that provides 8 mono or 4 stereo channels of amplification. For the “human interface” we use (8) “Direct Menu Select” Keypads (PLK-DMS) and 2 portable Viewpoint RF TouchPanels (VPT-CP) with a RF Receiver (PMB-RF) to control all house functions including fourteen Smart Dimmer (PLK-MLC) light switches and 5 Smart 3-Way (PLK-3WAY) switches (both now discontinued by AMX) to control house lighting, and two Communicating Thermostats (PCC-300) to control the HVAC (heating and cooling) system through the AMX Landmark system. The system components are interconnected using category 5 (CAT5) wiring installed in the walls of the home as it was being constructed.
The computer system that supports the Landmark home automation system is not manufactured by AMX but is a standard IBMâ computer with a 166MHz Pentiumâ processor. This computer is used primarily to do system programming. Although the LANDMARK system can contain and run most of the program independently, the computer is also needed for the DTMF telephone functions and to supply “.wav” (sound) files for the system. It is also very handy to have a computer for backup and to make quick changes in the system program.
The Card Frame with a 10 card capacity is used in our system to house and power the following cards:
¨A Master Control Unit (PLC-MCU4), which is the “computer” component of the system, and contains 4 Mb (Megabytes) of eeprom (Electrically Erasable Programmable Read-Only Memory) to contain the programming and for system functions.
¨Two 4 output Infrared Out cards (PLC-IROUT) to transmit IR signals to control equipment such as television sets, stereo equipment, motorized drapes or skylights or any other equipment that is normally controlled by IR remotes or “clickers”.
¨A Dual Tone, Multi-frequency card (PLC-DTMF) that allows the system to become a “telephone answering machine” and utilize computer “.wav” files for outgoing messages and to respond to telephone tone “commands” for communicating with the system from a remote location.
A two port Serial Interface Card (PLC-SER) which interfaces with house HVAC system via the two “smart” thermostats, and the entry/egress (door lock and control) system manufactured by IeI â.
¨2 Relay Cards (PLC-RL8) which provides 8 relays (each) to control anything that can be controlled by a relay such as the heated floor in the master bathroom, the pump and lights on the outdoor fishpond, the garage door open/close function and the solenoid locks on the front and back doors.
¨2 Contact Cards (PLC-IN7) which provides 7 inputs (each) for sensing contact closures for sensing such things as whether the garage door is open or closed, doors or windows are open or closed, and provide a voice announcement of motion detected outside or a vehicle entering the driveway (detected by the CARTELLâ driveway sensor).
Although not specifically in the Card Frame, I should mention that a “PHASTVerter” is used to interface with the APEX ADEMCOâ security system.
