The TS Files
TS File #..7
Environmental Control System:
Client: Male, late twenties. High level quadriplegic. Operates an electric
wheelchair with his chin.
Devices to be operated: Two Televisions (Lounge &
Bedroom), Telephone, Bedroom Lamp, Lounge Lamp, Stereo (on/off), Fan, Bedroom
Reverse Cycle Air Conditioner, Electric Sliding Door, Intercom Between unit
and main house.
Switch Systems: Two operating locations had to be accommodated; mobile use
from the wheelchair, and in bed. We looked at all the devices to be controlled
and listed which devices had to be operated from which location. For example,
the bedroom television would only be used from in bed, and the lounge room
television would never be used from in bed.
System Description The system was based on an Envicom 10, a hard wired visual
scanning control system capable of switching mains and low voltage devices.
While in the wheelchair, a radio linked suck/blow switch was used. The blow
operation operated the Envicom, and the suck directly operated the lounge
room television.

A separate radio transmitter was used to directly operate the electric door.
The radio links had sufficient range to be used outside, which meant household
security was also taken care of.
Separate scanning television controllers were used
for each set, and connected using the Envicom as a sort of switch director
- the envicom directs the blow switch activations to the appropriate TV Controller.
The reverse cycle air conditioner needed a fifteen Amp supply, so an adaptor
was made that switched the unit on and off, but did not actually draw power
from the Envicom. The lamps were simply plugged into the Envicom with extension
leads. The intercom was already built into the Envicom, and was a simple matter
to install by running a cable to the main house.
