1.3Description
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 copilot and passengers.
A front panel mode switch allows the pilot to select multiple intercom configurations:
"ISO" mode isolates the pilot from the intercom 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 communications.
"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 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 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 aircraft radio activity, this music is automatically muted to allow communications without distraction. When the activity ceases, the Soft Mute circuit will gradually return the music to the original listening volume.
The "ISO" mode provides uninterrupted aircraft radio communications for the Pilot. Because the pilot'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 pilot places the aircraft radio in the foreground while the ICS is in the background.
Both pilot and copilot have transmit capabilities over the radio. The PM1000II 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, the copilot will override (Ideally suited for training environments). Pilot regains priority by switching the unit off.
1.4Approval Basis *None*
The PM1000II, part numbers 11906 and 11908 are NOT FAA Approved. It is the installer’s responsibility to determine suitability for use.

Section 2 Installation
2.1General Information
The PM1000II comes with all necessary hardware for installation.
Installation of the PM1000II, using hardware supplied, and the wiring available separately from PS Engineering or approved sources, does not require special tools or knowledge other than described in FAA Advisory Circular 43.13-2B. It is the installer's responsibility to determine the approval basis for this installation.
2.2Unpacking and inspection
The PM1000II was carefully inspected mechanically and thoroughly tested electronically before shipment. It should be free of electrical or cosmetic defect.
Upon receipt, verify that the parts kit includes

2.3 Equipment installation procedures
1.Using the template, drill six holes in the instrument panel in a location convenient to the pilot position
(s).
2.Insert the PM1000II from behind the instrument panel, aligning the holes for the knobs, LED, and switch.
3.Place the aluminum face-plate over the knob shafts and secure, using the two # 4-40 round head screws provided.

2.2Cable harness wiring
To complete the installation, a wire harness must be made as shown in Appendix D.
PS Engineering can make a custom-tailored wiring harness for the installer. All harnesses use Mil-spec quality components with professional techniques, and are fully tested before shipment. Contact PS Engineering for more information.
If the aircraft already has pilot and copilot headset jacks installed, you may re-use them. Remove and discard all wires from the copilot headset jacks. You may use the existing pilot headset jacks as the Auxiliary Aircraft Radio Headset Jacks, but they should be moved to a new location to avoid confusion with the pilot's headphone jacks. In the event the intercom has to be removed for any reason, these jacks provide access to the aircraft radio system.
NOTE: Auxiliary microphone and headset jacks are required for a complete installation. These
provide troubleshooting and a back-up access to the aircraft radios.
