AUDIOACCESS System Operation The Audioaccess remote KPS and KP3 keypads and handheld IR remotes are an integral part of a PX-600/PX-603 system. They are, to a large extent, the whole system from your clients’ point of view. For a description of the operation of a PX-600/PX-603 system from a KPS keypad or IR remote controller, see the PX-600 Installation Manual.
• To turn off an ALL-ON group, momentarily press the ON button from any room within the group. • To turn off all rooms in the system regardless of ALL-ON grouping, go to any keypad, make sure it is ON, then press-and-hold the ON button until the red ON LED flashes on the keypad (about 2 seconds). VOLUME ▲ ▼ • To increase the volume, press ▲. To decrease the volume, press ▼. • To mute the audio, press ▲ and ▼ together. (Press the MUTE button on the IR remote control to get the same response.
AUDIOACCESS System Installation Pre-wire As in the PX-600 Installation Manual, we strongly suggest home-run wiring for all KPSs and PX-603s in every system. Although a list of reasons for doing so appears in the PX-600 Installation Manual, several points are worth repeating here: • Systems will be more easily serviced. • Trouble-shooting time will be reduced. • It is much easier to locate a faulty component. • You and your clients will be happier if you can isolate and correct problems quickly.
Home-Run Wiring Ideally, all KPS and PX-603 wiring should be home-run separately to one or more KPTs, then to the KEYPAD input on the PX-600 rear panel. This is the safest, most reliable method. Each KPS and PX-603 should be connected to a separate connector on the KPT. If you require more than six connections, use another KPT. Keypad Mounting and Connection Mount the KPS and KP3 keypads in ordinary electrical boxes or plaster rings.
AUDIOACCESS The KPS and KP3 IR Receivers Many people confuse the IR receiver on a KPS or KP3 keypad with an IR repeater. The KPS IR receiver takes specific IR signals from the Audioaccess RT-A or the URC-8090 and decodes them at the keypad. The KP3 IR receiver sends the IR information as electrical signals to the PX-603, where the signal is decoded as in the KPS. Control data is then sent to the PX-600. No actual IR signal is transmitted to the PX-600 from the KPS or KP3 keypad.
Keypad Connectors The KP3 jacks are numbered according to the PX-603 room they control. Connect KP3 keypads directly to the back of the PX-603 using six-conductor 22-24 AWG wire terminated with six-conductor modular plugs (see diagram 1 on page 9). A KPS may be used in any PX-603 room if source selection is desired.
AUDIOACCESS For a single-PX-600 system, set the SYSTEM CODE to “0” (switches 5 - 7 down). In a multi PX-600 system, set the SYSTEM CODE to the number of the corresponding PX-600. The SYSTEM CODE switches, when in the "UP" or "ON" position, have these values: SW 5=1, SW 6=2 and SW 7=4. Add them together to get totals equal to the system number, up to System Six.
ZONE, SYSTEM and ROOM code settings are the same for the DIP switches on the KPS keypads (see the PX-600 Installation Manual for a description of KPS switches 9 and 10). PX-603 rooms that are controlled by KPS keypads must have both the PX-603 Room Configuration DIP switches and KPS DIP switches set in the manner described above, rather than as in the PX-600 Installation Manual. Room setting for KPSs in the main room of the zone is 0 – switches 4 and 8 down.
AUDIOACCESS Zone Setup Zone setup is accomplished as described in the PX-600 Installation Manual, with the following change: All zone names default to ZN#__MAIN, however you may manually name each main room to reflect its primary function. 1. Select ZONE SETUP from the MAIN MENU. 2. Select a ZONE. 3. Select NAME. 4. Use ▲ and ▼ to select letters and numbers to designate a name for this zone. Press ENTER after each character. 5. Continue as described in the PX-600 Installation Manual. 6.
5. The next screen lists the zone group setting, along with three PX-603 rooms available for each zone. The default setting for all PX-603 rooms is N (no), meaning that no PX-603 rooms assigned to the zone group will come on when the ALL-ON command is activated. For zones with no PX-603 rooms, no change is required in this screen. For zones containing PX-603 rooms, select Y (yes) or N (no) to include or exempt PX-603 rooms as part of the ALL-ON group. 6.
AUDIOACCESS Appendix I System Design Particular suggestions for system design have come from our most successful dealers. Guidelines for setting up Audioaccess systems can be found in the System Design portion of the PX-600 Installation Manual. Please refer to this section; we believe you’ll gain some important benefits from these general practices. Designing systems to include the PX-603 requires clarification of two terms used in discussing Multi-Room systems.
System 1 Block Diagram Block Diagram One describes both direct connection of the PX-600/603 for adding a single room to a zone and adding multiple rooms to a zone. It also contains examples for determining how much amplification is necessary in each area. Zones 1 through 3 have the straight-forward configuration of standard PX-600 systems. Each uses one stereo pair of the PX-612 amplifier and has independent source and volume control via a KPS keypad.

AUDIOACCESS Appendix II Dealer/Manufacturer Questions and Answers At Audioaccess, we believe our dealers are an integral part of our marketing, design and manufacturing team. The PX-603 is a direct product response to requests from dealers for a cost-effective way to expand multi-room systems without having to use remote amps and autoformers.
Q: Can I use the PX-603 for outdoor areas? A: This application is not recommended. The amplifier puts out 22 watts, which isn’t enough for outdoor use most of the time. It is fine for a small pool house, cabana, or enclosed porch though. (See page 16) Q: Will I be able to page into PX-603 rooms with a PDM? Can rooms be programmed for paging independently from the main room of the zone? A: Yes, paging is available in PX-603 rooms as long as the zone is programmed for paging.
AUDIOACCESS Appendix III Troubleshooting Guide System locks up with PX-603 attached • Check PX-600 software version. • Check wiring for shorts, splits and insulation caught in screw-terminals at the PX-603, KPSs, and KPT. • Check PX-603 and KPS DIP settings. • Check KPS and KP3 keypads for IR interference. KPS keypads don’t control PX-603 rooms • Check DIP settings on keypads and the PX-603. • Check keypad wiring.
