Section II -Installation
2.1 GENERAL INFORMATION
2.1.1 SCOPE
This section provides detailed installation and interconnect instructions for the PS Engineering
PMA6000B-Series Audio Selector Panel/Intercom System and PMA6000B-Series Audio Selector
Panel/Intercom System with internal Marker Beacon.
With the exception of the internal marker beacon receiver, the audio panels are identical.
Please read this manual carefully before beginning any installation to prevent damage and post installa-
tion problems. Installation of this equipment requires special tools and knowledge. The equipment must
be installed by an appropriately rated Certified Aircraft Repair Station, in accordance with applicable
regulations.
NOTE: The PMA6000B-Series requires specialized knowledge equipment and tools for an effective in-
stallation. An appropriately rated Certified Aircraft Repair Station must install this equipment in accor-
dance with applicable regulations. PS Engineering, Incorporated warranty is not valid unless the equip-
ment is installed by an authorized PS Engineering, Incorporated dealer. Failure to follow any of the
installation instructions, or installation by a non-certified individual or agency will void the warranty, and
may result in an unairworthy installation.
2.2 Unpacking and Preliminary Inspection
Use care when unpacking the equipment. Inspect the units and parts supplied for visible signs of shipping
damage. Examine the unit for loose or broken buttons, bent knobs, etc. Verify the correct quantity of
components supplied with the list in Section 1.6 (B). If any claim is to be made, save the shipping mate-
rial and contact the freight carrier. Do NOT return units damaged in shipping to PS Engineering. If the
unit or accessories shows any sign of external shipping damage, contact PS Engineering to arrange for a
replacement. Under no circumstances attempt to install a damaged unit in an aircraft. Equipment returned
to PS Engineering for any other reason should be shipped in the original PS Engineering packaging, or
other UPS approved packaging.
2.3 Equipment Installation Procedures
2.3.1 Cooling Requirements
Forced-air cooling of the PMA6000B is not required. However the unit should be kept away from heat
producing sources (i.e. defrost or heater ducts, dropping resistors, heat producing avionics) without ade-
quate cooling air provided.
NOTICE: To reduce the amount of heat dissipated in the audio selector panel, when used in a 28
Volt aircraft, it is required that the 15 , 15-Watt dropping resistor (p/n 701-015-1501) be in-
stalled in series with the power input.
If the PMA6000B is installed in a 27.5 VDC aircraft system, a 15 , 15 Watt dropping resistor (p/n 701-
015-1501) should be installed. Failure to do so will generate unnecessary heat inside the unit and may
void PS Engineering's warranty.
