Section I General Information
1.1 Introduction
The PM1000-DAP, is a panel mounted, 2place intercom system (ICS) designed for installation in aircraft with existing dual audio control
panels (ACP). 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:
Part Number Description
11900D w/Pilot ISO for Dual ACP Installation
1.3 Description
The PM1000-DAP is a 2-place, panel
mounted intercom with individual volume and
squelch controls for the pilot and copilot. This
unit is specifically designed to provide voiceactivated intercom in a dual audio control panel
aircraft.
A front panel mode switch allows the pilot
to select multiple intercom configurations:
"ISO" mode isolates the pilots from the
intercom and connects to the aircraft radio. This
mode defeats the intercom capability. The copilot retains all radio functions.
"ALL" mode places all headsets on a party
line. Each pilot hears their selected aircraft radio, entertainment and can use the intercom.
“CREW” (only
expansion unit ) allows the pilot and copilot
positions to hear the aircraft radios and use the
intercom, while the rear passengers can have
if equipped with optional
their own intercom conversation without disturbing the crew.
The LED shows green when power is on, and
is not a transmit indicator. The PM1000-DAP
does not have a direct interconnection with the
aircraft audio, and therefore will not affect operation if power is removed.
Because the crew’s intercom volume control
does not affect 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 pilots can place the aircraft radio in the foreground while the ICS is in the background.
1.4 Approval Basis FAA-TSO
The PM1000-DAP, part is FAA Approved
under TSO-C50c. It is the installer’s responsibility to determine approval basis (Part 91, 121, Part
135, etc.) and suitability for use.
