Section I General Information
1.1 Introduction
The PM1000 is an FAA-TSO approved, panel mounted, 2-place intercom system (ICS). Please read this
manual completely before installation to minimize the risk of damage to the unit and to become familiar with
all the features.
1.2 Scope
This manual contains installation and operational instructions for the following PS Engineering unit:
Model Description Part Number
PM1000 2-place intercom system 11900
1.3 Description
The PM1000 is a 2-place, panel-mounted intercom with individual volume and squelch controls for the pilot
and copilot positions.
A front panel mode switch allows the pilot to select one of two possible configurations:
"ISO" mode isolates the pilot from the intercom and connects to the aircraft radio. The copilot can continue
listen to entertainment without distracting the pilot. This position will not hear radio communications.
"ALL" mode places all headsets on a party line. Each one hears aircraft radio, entertainment and can use the
intercom.
The PM1000 has an automatic fail-safe interconnect to the aircraft radio. If power to the intercom is
disrupted, an internal relay will connect the pilot's headset to the aircraft radio. This allows continuous radio
communications. Note: The copilot will no longer hear aircraft radio when power is removed.
The LED shows green when power is applied to the unit.
An auxiliary input is provided, allowing the pilot and copilot the option to listen to music during flight.
During intercom activity, this music is automatically muted to allow communications without distraction.
When the activity ceases, the music returns to the original listening volume.
Note: the music is NOT muted during radio reception. During times when radio communication is vital, the
pilot should select “ISO” mode. Other occasions where radio is of lessor importance, it is possible to put the
intercom in the background by reducing the PM1000 volume. The pilot volume control doesn’t effect the
volume of the aircraft radio, so it can be adjusted to a more prominent level.
Both pilot and copilot have transmit capabilities over the radio. The PM1000 allows only the person who
presses their PTT to be heard over the aircraft radio. If both pilot and copilot press the PTT at the same time,
