Comtronics Engineering
has introduced the first panel-mount intercom designed exclusively for
Part-103 ultralight trainers. This intercom is designed to be a "Plug-N-
Play" system and occupies a space of only 2 1/8 X 61/8 inch on the
instrument panel.
The three main components are a panel-mount intercom,
remote station for copilot! student access and push-to-talk switch. All
cables are included and completely assembled ready to plug in except the
radio interface and music cords which must be purchased separately. Music
cord can be owner-fabricated to fit or assembled at our facility.
Exact
lengths required. A music cord may be interfaced with a tape player, CD or
AM/FM radio. Music feature has an on/off switch located on face plate. A
horizontal 1 3/8" X 5 5/8" cut-out through the instrument panel and four
5/32 diameter holes to match holes in face plate are required to mount
intercom.
The remote station has a
volume control and can be conveniently mounted for copilot/ student- ideal
for tandem seating. Due to a variety of options, the remote station is not
drilled for mounting hardware. Brackets must be owner-fabricated securing
these units to airframe. Two (2) No.6 machine screws with washers and lock
nuts are recommended.
This panel-mounted
intercom can be interfaced with two transceivers using related cables
which must be purchased separately. Interface cables are available for all
aircraft radios as well as most CB, business, marine and family-band
transceivers. Call with make and model.
A very efficient
switching circuit makes the unit more versatile. It provides the pilot an
option to transmit on either radio while monitoring both simultaneously
simply by using a radio selector switch on the panel. A push-to-talk
switch is provided with each sys- tem and can be mounted on the crossbar.
Exact length of cable must be specified if switch is to be permanently
mounted on joystick.
The entire circuitry is
enclosed within a rugged metal enclosure of overlapping construction to
effectively shield out RF and EMI interference. This equipment requires an
aircraft regulated 12-volt power supply with a negative ground.
