The Model 091-133 418 MHz Transmitter/Receiver is a remote control system
between a vehicle and a building. It is intended to operate various electrical
devices in the building when signaled to do so from the vehicle. The Transmitter
is installed in the vehicle above the dash and near the windshield. The receiver
is installed on a shelf or on a wall, away from large metallic surfaces. The
transmitter and receiver have four proprietary channels; channels 6, 7,8, & 9.
Channel 9 is dedicated to automatically producing a 1 second closed contact at
the receiver channel 9 output upon the ignition switch being turned on. This is
intended to actuate the Fan Controller in the building. The other three channels
could be used to open the door, close the door, or stop door movement. The
other three channels are operated by momentary push button switch mounted on
the dashboard by the installer.
Each Transmitter and Receiver can be coded using a DIP switch mounted on
each unit. In this way any number of proprietary channels can be implemented.
The Transmitter is of such low power that a license is not required to
operate it, and it has a range of 150 feet to the receiver. For single receiver
systems; each truck can have a transmitter which will communicate with
the single receiver. For multiple Receiver systems each Receiver will be
assigned a code. A given Transmitter will only communicate with a
receiver if it has the code as that receiver. Dip switches on the Receiver
and Transmitter code the Transmitter and Receiver. Thirty-two different
codes are possible.

antenna vertical.
