System Components

(Including Series III (bold)

*See page 15 and 16 for hub configurations

1-on-1 Audio or A-V Installation

The simplest system configuration involves only one counter station connected directly to one lane station (no hub).
This configuration can be audio-only or audio-video. Run a length of Cat 5 cable from the counter location to the lane location. Separate camera and monitor may be installed and connected to a 1520B, or the 1527AVB may be connected, which includes those peripherals in the enclosure See page 11 for detailed instructions.
Note: In systems without a hub, the only way to upgrade firmware is to temporarily connect a hub in the system and a 1550A to the counter station while performing these operations.

1-on-2 Audio Installation

The dual lane audio configuration involves only one audio counter station serving two lanes (no hub). This configuration is audio-only Run a length of Cat 6 cable from the counter location to the dual lane station The 1522B may be located inside near the counter station or outside in a sheltered location such as up in the canopy over the lanes When running wiring to lane devices be sure to protect individual wires or use an approved multi-conductor cable.
Note: In systems without a hub, the only way to upgrade firmware is to temporarily connect a hub in the system and a 1550A to the counter station while performing these operations.

2-on-4 Audio Installation (Audio Mini Hub)

The Model 1509B audio mini hub allows one or two Model 1500B counter stations to serve up to four 1520B lane stations Run a length of Cat 5 cable from each counter station to the Hub Run a length of Cat 5 cable from the Hub to each lane station Mini hubs now allow for custom key assignments via the1550A installer setup tool (see page 18).

2-on-4 Video and Audio Installation (Video Mini Hub)

The Model 1509BV A-V mini hub allows one or two Model 1500B counter stations to serve up to four 1520B lane stations Run a length of Cat 5 cable from each counter station to the Hub Run a length of Cat 5 cable from the Hub to each lane station Mini hubs now allow for custom key assignments via the1550 installer setup tool For separate camera and monitor, connect via BNC ports on 1520B.

Wiring
Series 1500 is designed for excellent performance using Cat 5 cable (Cat 5e / 6 / 7 is Unshielded Twisted Pair cable that carries multiple signals for long distances). Follow instructions below, or in retrofit installations where the existing wiring must be used, refer to 1500 alternate wiring instructions (752-502) at www.audioauthority.com.

Cat 5 Cable Fabrication

Terminate the ends of each Cat 5e/6 cable with RJ-45 modular plugs using the EIA 568B pinout (paired 1-2, 3-6, 4-5, and 7-8). Premade network cables may also be used for shorter runs TEST all cables (including pre-made) with a network cable tester.

Installing 1500B Counter Stations

1. Unpack each Model 1500B counter station and, if applicable, install a 1502B video display. Plug the Cat 5 video cable into the matching port on the 1500B.
2. Attach the field-replaceable microphone, tightening the nut securely with a 18mm flare nut wrench, and tuck its rubber boot firmly into place.
3. Plug the Cat 5 cable from the hub into the hub port of each 1500B and connect the power supply to the Power jack
4. Pry up the keypad cover and install the desired key colors in the Model 1500B. On initial power-up, the hub sets the default key layout automatically according to the number of connected Counter and lane stations (see examples below). You can choose to color-code by the carrier color or label the keys numerically Place blank, black chips in all non-active positions. Store the unused key chips on the premises for future changes or expansion.

Installing 1502B Video Monitor

2. Run a length of Cat 5 cable from each counter and lane station to the hub Observe the fabrication guide on page 8, and use a cable tester to verify the terminations.
3. Apply hub power last, and adjust volume level during system testing.

Installing the A-V System Hub (1510, 1511, 1512)

1. Position and install the hub under the counter or in a secure indoor location such as a telephone closet Ground the hub to a nearby electrical outlet cover using the green grounding wire attached to the hub.
2. If the installation requires additional capacity, install a counter card or lane card(s) as needed (see page 16).
3. Run a length of Cat 5 cable from each counter and lane station to the hub Observe the cable fabrication guide on page 11, and use a cable tester to verify the terminations.
4. Connect other equipment as needed .
   See page 11 for more on program audio.
5. After lanes are connected, apply power to the hub.

A-V System Hub Model 1510

• The Model 1510A is an audio-video hub with a capacity of up to four counter stations serving four lane stations The hub’s capacity can be expanded in the field by adding counter and/or lane cards (see page 16).
• System settings can be stored on a standard SD card for security or replication purposes Firmware upgrades can be downloaded from the Audio Authority website and performed using the SD card when necessary These operations require a Model 1550A installer setup tool and a counter station.
• Composite video and stereo analog audio inputs allow multimedia source devices to play advertising content on any lane whenever customer is on hold or it is idle See page 12 for details.
• Direct outputs from wide angle camera (dedicated security camera) and/or lane cameras for surveillance recording Video is output continuously from each camera connected.

Hub Configurations and Capacity

Shown below is the A-V hub with a maximum capacity configuration. Other pre-installed configurations are available; contact Audio Authority® for details, or visit www.audioauthority.com.
Add Cards to Increase Capacity
To increase counter or lane station capacity, remove power from the hub. Remove the blank faceplate from the appropriate card slot(s) and insert the new cards carefully, making sure the connections are firmly seated. Insert the two screws to secure the card, and connect new lane stations or counter stations. Connect power and test the system.Using Traffic Sensors
Lane stations provide an RJ45 connection for Audio Authority’s Model 1547B traffic sensor. When a vehicle triggers the 1547B, the counter station generates a call tone for the corresponding lane to alert the operator. The call tone for the traffic sensor can be a different ring tone from the call button at the same lane (see page 22). To extend a traffic sensor, use an in-line coupler and a length of Cat 5 cable.
A third party traffic sensor may be used by connecting it to the TRAFFIC SENSE terminal (pin 6) and COMMON terminal (pin 8). Third party sensors have different pinouts and color codes. Be sure to verify the specific pinout with the manufacturer’s documentation.
Using Ringtones
16 different ringtones are available in the 1500 system Operators may choose a distinct ringtone for each counter station and adjust the ringtone volume using console controls (see operator instruction card on page 13) Using the 1550A the installer may assign each lane a distinct ringtone (see ringtone override, page 18), and designate one ringtone for IR traffic sensors, and a different one for call buttons (see menu map, page 22).

Playing Audio and Video Content Through Lane Stations

If audio or video messaging content will be playing when customers are on hold or the lane is idle, plug the source player into the PROGRAM INPUT ports on the 1517A hub card Program audio level may be manually adjusted at the hub Any lane’s program audio may be turned off during idle periods (still heard while on hold) using the 1550A Program Audio Abate setting (see page 18). If the program video source is a PC, either a composite video card or external converter is required to scale the PC video output to standard definition composite video signal.

Using the 1550A Installer Setup Tool

System Calibration and Setup
The Model 1550A is a display that shows the setup menus and settings for Series 1500 Intercom Systems See page 22 for a menu map and default values The entire system can be calibrated from one counter station.
Connect the CAT 5E/6 cable to the RJ45 jack on the underside of any live counter station (the jack is at an angle) Return the counter station to its upright position and connect the 1550A Setup Tool If the counter station has an attached handset cradle (1500AH or 1503B, etc.) make sure the handset is resting in the cradle before you connect the 1550A.

Basic Setup Procedure

• Hold the SETUP key on the counter station for one second to enter Setup mode The 1550A displays: “SERIES 1500 EQUIPMENT CALIBRATION PLATFORM”.
• To navigate the menus, use the VOLUME UP and VOLUME DOWN keys to move the cursor.
• Touch SETUP to enter a submenu or confirm a selection, and PRIVACY to go back.
• Any changes you make are recorded as you exit each submenu. When you exit Setup mode, you must choose to either save all changes and exit or exit without saving.

Power User Tips

• For faster menu navigation, submenus may be selected by touching a key that is lit RED corresponding to the menu item (see the numbered keys above). For instance, to enter BLOWER MOTOR DELAY, press 1 and then 1.
• See page 22 for a menu map and default values.
• To exit Setup mode from any menu, hold SETUP for one second and follow the prompts on the 1550A.
• After adjusting a lane station or counter station, you can use the CAMERA UP or CAMERA DOWN keys to select other stations for adjustment without leaving the submenu.

Using an SD Card
SD cards have two uses for Series 1500 systems: Store intercom configuration data and upgrade the system firmware.

• Use the SD card to back up configuration of the intercom system so that you can restore settings later, or program another system. This can save time from one installation to the next if the installations are similar. The system settings can also be retrieved from the memory card in case of a system upgrade or equipment replacement.
• To store configuration data on the memory card, insert the card into the hub and perform a WRITE TO MEM.CARD operation in the SETUP menu (see page 22). Then remove the card and store it on-site in a safe, designated location.
  If you intend to copy the settings for another system, write the configuration data to an additional SD card.
• To load a configuration from the SD card, insert the card into the hub and perform a READ FROM MEM.CARD operation in the SETUP menu (see page 22)

Troubleshooting Tips

• Always test Cat 5 cables with a professional Network Cable Tester – even pre-made cables (see page 8).
• Try connecting a counter station directly to a lane station to rule out faulty system components.
• In case of unexpected behavior, restore system defaults to rule out incorrect system parameters.
• If a lane does not show up on the hub, insert a firmware SD card into the hub and reboot it.

Counter station lights in a pattern

• Faulty Cat 5 cable – consistently use EIA 568B standard cable termination (see page 8).
• Counter station connected to the wrong hub port.

Low volume at counter station

• Adjust inbound or open loop gain levels.

Acoustical coupling

• Increase separation of lane microphone and speaker.
• Isolate lane microphone and speaker with sound- damping barrier (i e foam rubber).
• Mount lane speaker and microphone on separate surfaces or adjust their mounting angles.
• If the above remedies do not solve the problem, adjust inbound, outbound or open loop gain levels.

Poor deal drawer acoustics

• Fill hollow cavities in the deal drawer with foam rubber sheets or blocks.
• Do not rest counter station directly on deal drawer.

Repeating pops in audio

• Check cables – EIA 568B termination (see page 8).
• Check system ground connections.

No video or poor video quality

• Check Cat 5 cables – consistently use EIA 568B standard cable termination (see page 8).
• Eliminate long coaxial cable runs between cameras displays and lane station.
• Check microphone wiring polarity.

Lane indicator does not light up on hub

• Insert a firmware SD card into the hub and reboot it.
  If the lane station does not recover within 15 minutes, it may need to be replaced

Lane keys don’t respond

• Keys not assigned to counter station – reassign keys or restore factory defaults in configuration menu.

Lane microphone doesn’t work

• Microphone must be electret condenser type
• Check microphone polarity

Wind noise

• Can often be eliminated by putting a small plug of 3M Scotchbrite™ in the microphone opening
• For optimum results, use Audio Authority lane microphones which are designed to shield from wind
