The Tone Commander 524 is a call processing console for use in receptionist or departmental attendant
positions, with Centrex or PABX systems. Five line keys are provided for LDN (listed directory number)
terminations or call processing loops. Up to 24 stations may be monitored for status. Autodialing is
available for each station. Autodialing is normally used to dial the station number associated with the DSS
(Direct Station Select) key, but spare DSS keys may optionally dial outside lines or special access codes.
Features include hold and transfer, single button call answer, line privacy, delayed ringing, station status
display, station name display, music on hold, and a digital clock. Console parameters may be programmed
by the installer for different system configurations.
A configuration programming mode is used by the installer to set console parameters as required by the
telephone system. The attendant may program name displays, autodial numbers, ring delays, and the
time-of-day clock. Switches can be set to prevent accidental programming changes.
The system includes a CPU (Central Processing Unit) in the equipment room. Two consoles may be
connected to a single CPU.
Please refer to the System Description

3. Site Preparation
Central Processing Unit (CPU)
The CPU should be installed in a clean, dry area which is secure but also accessible by maintenance
personnel. This unit is designed for wall mounting only. Allow adequate wall space for ventilation, the
necessary mounting blocks, and related equipment.
Ambient Environmental Requirements
1. Between 60° and 80° F (recommended).
2. Free of toxic fumes or static electricity (copiers).
3. At least 50 feet away from electromagnetic sources (arc welders).
4. Free from transient electrical load switching equipment (elevator rooms).
5. Between 5% and 95% noncondensing relative humidity.
Power Requirements
A dedicated, 15 amp, 117 VAC, 60 Hz circuit must be provided for the exclusive use of the CPU.
IMPORTANT – Ancillary or unrelated equipment should never draw power from the same circuit that
powers the CPU.
The ground (3rd prong) on the power plug provides a safety ground to the chassis of the CPU, and is
required for EMI shielding. It must be plugged into a grounded outlet.
Transient Surge and Spike Protection
While Tone Commander products comply to FCC rules part 68.306, Hazard Voltage Limitations
areas of high lightning activity, the use of external protection devices on all telephone lines and the power
source is recommended.
Reference Grounding
Reference grounding of the 524 system is necessary for proper operation. This ground should be
referenced to within 3 volts of telco ground.
, in those
Attendant Consoles
The consoles should be installed in a clear work space and away from plants that require frequent watering
or counters that tempt the placement of beverages.
Ambient Environmental Requirements
It is recommended that the same environmental conditions be maintained for the consoles as one would
maintain for a personal computer (PC) or data terminal.
Power Requirements
Console operating power is provided by the CPU.

A space is provided on the Configuration Sheet for the Directed Call Pickup code required by the telephone
system.
Station and Line Programmable Features
1. Phone number and name identification for each line. Refer to the DSS/Autodial Number
Programming section.
2. Programmable features for each line (Privacy, Answer Use).
3. Station number and user name identification for each station. Include any additional functions to be
dialed with the DSS number, such as an FD prefix.
4. Autodial numbers for spare DSS keys.
Sample Configuration Sheets are provided on the following three pages.

Tone Commander 524 Installation Instructions
CPU Installation
Mounting CPU and Blocks
Refer to Figure 5.
1. Fasten a plywood sheet to the wall with hardware suitable for the wall material.
2. Using the supplied mounting template, mark and pre-drill the mounting holes for the CPU.
Make sure that the CPU mounting location is within 5 feet of a standard 117 VAC, 60 Hz grounded
power outlet.
Allow at least one foot of free space above and below the CPU for ventilation.
3. Drive in four suitable fasteners (such as #10×¾" pan head tapping screws), leaving the heads out ¼".
4. Remove the two cover screws, turn each CPU cover fastener so that the slots are horizontal, then
remove the cover.
When installation and testing are completed, replace the cover, turn each cover fastener so that
the slots are vertical, then lock it in place with the cover screws to assure compliance with UL
requirements. If the cover screws need to be replaced, use 6-32×¼" pan head machine screws.
5. Hang the CPU on the four mounting screws and tighten the screws.
6. Label each side of the split terminal blocks as shown in the Designation columns of Tables 1 and 2.
7. Mount the blocks to the plywood sheet below the CPU, using suitable fasteners.
Cabling to Blocks
Refer to Figure 5.
1. Punch down the cables to the blocks as shown in the Wire Color columns of Tables 1 and 2. The cable
with the male connector should be punched down to the right side of block #1.
2. Plug the 25 pair cable from block #1 into the connector on the left side of the CPU circuit board.
3. Plug the cable from the left side of block #2 into the connector on the lower right side of the CPU circuit
board.
4. Plug the cable from the right side of block #2 into the connector on the upper right side of the CPU
circuit board.
5. Secure the cables with the supplied cable retainers.

Tone Commander 524 Installation Instructions
Reference Grounding
Reference grounding of the 524 is necessary for proper operation.
Connect telco or PABX ground to the GRD pin on the
bottom right of CPU block #1.
DO NOT connect this reference ground to the CPU's
metal housing!
Figure 1
CPU Chassis Grounding
This ground connection is required for safety and EMI shielding. It is usually provided by the 3rd wire on
the CPU power cord. If the integrity of the power outlet ground is questionable, use the ground connection
shown below for the 524 CPU.
Figure 2
1. Connect a solid copper #10 or #12 AWG wire to the ground terminal on the CPU. The wire should be
tightly clamped between the ground screw and the cup washer.
2. Connect the wire to an approved ground, such as MGN (multi-grounded neutral) from the power lines,
building ground, a metallic cold water pipe, or a grounding rod.
Page 1413-102408 Rev. H
Connections to Telco/PABX Lines
Figure 3
Tone Commander 524 Installation Instructions
1. Connect Tip and Ring of each line to the associated
T and R pair on the right side of CPU block #1.
If the 524 is used with a key system, connect to the
C.O. side of the line cards.
2. If this installation has stations paralleled with console
lines, the stations should be connected to Tip and
Ring at the telco/PABX block.
Line Testing
Connect a test telephone to each line; verify the presence of dial tone, and break dial tone by dialing a
number.
The 524 allows DTMF tone dialing only – refer to the Telco/PABX Requirements
Test any additional features ordered with the lines. Open circuit voltage must be approximately 48 volts.
section.
Station Connections
Station Monitoring
Connect T (Tip) and R (Ring) from each
monitored station to the associated T and R
pins on CPU block #2. The 524 is connected
in parallel with the station lines.
