1.1 Introduction
The PM1000II, is a panel mounted, 4-
place monaural 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.

This manual contains installation and op-
erational instructions for the following PS En-
gineering units:

1.3 Description
The PM1000II is a 4-place, panel mounted
intercom with individual volume and squelch
controls for the pilot and copilot. The copilot's
squelch control adjusts the trip level of the copi-
lot and passengers.
A front panel mode switch allows the pilot
to select multiple intercom configurations:
"ISO" mode isolates the pilot from the in-
PM1000II Specialty Intercom Manual
tercom and connects to the aircraft radio. The
passengers can continue to communicate with
each other and listen to entertainment without
distracting the pilot. They do not hear radio com-
munications.
"ALL" mode places all headsets on a party
line. Each one hears aircraft radio, entertainment
and can use the intercom.
"CREW" (11908 only) allows the pilot and
copilot positions to hear the aircraft radios and
use the intercom, while the rear passengers can
have their own intercom conversation without
disturbing the crew. This also activates music 2
input.
The PM1000II has an automatic fail-safe
interconnect to the aircraft radio. If power to the
intercom is disrupted, an internal relay will con-
nect 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 2-color LED shows green when power is
on and red during radio transmissions. This
functions as a stuck mic indicator.
An auxiliary input is provided, allowing the
pilot, copilot and passengers the option to listen
to music during flight. During intercom or air-
craft radio activity, this music is automatically
muted to allow communications without distrac-
tion. When the activity ceases, the Soft Mute cir-
cuit will gradually return the music to the origi-
nal listening volume.
The "ISO" mode provides uninterrupted air-
craft radio communications for the Pilot. Because
the pilot's intercom volume control does not af-
fect the aircraft radio volume, it is possible to
select various balances of volume level between
the ICS and the aircraft radio while in the ALL
mode. Reducing the intercom volume, the pilot
