the system is NOT powered. This critical step is detailed in 
”Power Up Sequence near the 
end of this chapter. 
						

							Preparation for DHS Installation2-23
General Site Considerations
The first step of DHS  installation, is to locate an acceptable site for the common 
equipment (KSUs, boards, etc.). When locating a mounting site for the KSUs, the 
following points must be considered:
†KSUs are designed for wall mounting and should not be mounted directly to a 
masonry or plasterboard wall. It is recommended that 1/2 in. plywood backboard be 
firmly mounted to the wall, and the KSU and MDF be mounted to the backboard.
†The location must have access to a dedicated 117V AC (±10%), 60 Hz, single-phase 
circuit with a circuit breaker or fuse rated at 15 amps. A 3-wire parallel blade 
grounded outlet should be within approximately 6 feet of the lower left rear of the 
KSU mounting.
†The location must have access to a good earth ground, such as a metallic cold water 
pipe without non-metallic joints. The ground source should be located as close as 
possible to the system.
†The system should be located in an area that is well ventilated with a recommended 
temperature range of 68-78° F and a relative humidity range of 5-60% (non 
condensing).
†The system should be located within 25 ft. of the telephone company’s termination 
point. Also, the location should be within the prescribed station loop lengths for all 
keysets and terminals. If existing cabling is used, its location and conduits should be 
considered. Station wiring should be in the building. Station ports are not designed 
for installation outside of the building.
†Protection from flooding, flammable materials, excessive dust and vibration.
†The site should be away from radio transmitting equipment, arc-welding devices, 
copying machines and other electrical equipment capable of generating electrical 
interferences.
†Operation of this equipment in a residential area is likely to cause interference. In 
which case the user, at his own expense, is required to take any necessary measures 
to correct the interference.
Necessary Tools and Supplies
To make installation easier, consult the following pages when preparing to install the 
system. 
Tools
The following tools are recommended to install your DHS system. Others may be needed 
for certain troubleshooting procedures.
†Use unshielded, twisted multi-pair (three-pair minimum recommended) cable to run 
from the MDF to all station instruments (key telephone and single-line DTMF 
telephones). Digital key telephones only need one twisted pair to operate.
Use shielded cable if RFI/EFI is expected. 
						

							2-24Preparation for DHS Installation
†Six conductor modular jack assemblies for all station instruments (recommended).
†Standard punch-down terminal block(s), 66M1-50 type, as required.
†Industry-standard, 25-pair cable(s) with a 50-pin male amphenol/AMP type 
connector for connection from each equipped 3 x 8 module to the MDF.
†AC voltage surge/spike protector.
†Standard telephone hand tools and mounting hardware for the KSU, MDF backboard,

							DHS Installation2-25
Verify On-Site Equipment
Once the equipment installation site is identified and a dedicated AC outlet, earth 
ground, adequate lighting and ventilation are available, verify that all equipment 
required is on-site and was not damaged during shipping:
†Unpacking the KSU  - The Key Service Unit is shipped in its own protective carton and 
contains the following:
†Basic KSU
†One mounting template
†One System Installation & Maintenance Manual
Open the carton and verify that all items are complete and undamaged. Remove all 
packing material and store for future use in the event that return shipment is 
required. This should be performed at the installer’s office with a 48-hour burn-in 
period prior to installation.
†Check that the type and quantity of boards received is correct. DO NOT unpack the 
individual boards at this time.
†Verify optional equipment is received and is in good condition.
†Verify that a Power Line Surge Protector is on-site.
DHS Installation
1. Backboard MDF Installation 
A wooden backboard is recommended for all installations and must be installed when 
the location has masonry or plasterboard walls. A 1/2 in. plywood material is sufficient for 
most installations.
1. Mount the backboard at a convenient height, about 3 ft. above the floor. It can be 
bolted in various places to distribute the weight of the system.
2. Space should be available on the bottom side of the backboard for the MDF cabling 
and for optional equipment such as a music source and battery backup.
3. It is recommended that the location of each major item be roughly sketched on the 
backboard as an installation layout.
4. Locate the Telco-provided CO/Centrex lines at the demarc and extend them to the 
MDF location.
If any equipment is damaged or missing, notify the appropriate personnel to correct the 
situation. 
						

							2-26DHS Installation
2. KSU Grounding 
To ensure that the system will operate properly, a good earth ground is recommended. 
The Telco protector ground terminal or a metallic COLD water pipe will usually provide a 
reliable ground path. If cold water pipe is used, carefully check that the pipe does not 
contain insulated joints that could isolate the ground. In the absence of the cold water 
pipe, a ground rod or other source may be used. A No. 8 AWG copper wire should be used 
between the ground source and the KSU. 
Voltage Surge/Spike Protection
To reduce the effects of AC voltage surges and spikes that may cause system 
malfunctions, false logic, and/or damage to the electronic components, it is 
recommended that a separately sourced surge/spike protector be installed. Check the 
manufacturers specifications to ensure that the device meets the following 
requirements: 
†The power cord should not be used with a 3-wire to 2-wire plug adapter. 
†A power line surge protector should be used to protect the power supply from 
electrical surges. The surge protector should be installed in accordance with the 
manufacturers instructions and applicable local electrical codes.
†Clamp voltage transients at 300V within 5 nsec. when exposed to wave-forms as 
described in the ANSI/IEEE Standard C62.41-1980 (IEEE 587).
†Reduce RFI/EMI noise by at least 20 dB at frequencies between 5 kHz and 30 MHz.
3. Battery Backup - System
External batteries may be connected to the KSU via the optional Starplus VC61101 
Battery Charging Unit (BCU). This unit may be equipped with batteries sized to meet the 
particular customer requirements. The approximate time, in back-up hours, is located in 
Table 2-11. In the event of a commercial power outage, the BCU will provide the 
necessary system voltage (24V) to allow full feature key telephone operation until AC 
power is restored or the battery voltage reaches minimum voltage thresholds and is 
automatically disconnected to avoid battery damage. This threshold is approximately 21 
to 21.5V. The amount of system battery operation time is dependent on several factors:
†Number and type of key telephones installed
†System traffic load
†Age of external batteries
†Equipment Room Temperature
†Amp/Hour rating of external batteries
†Recovery time since last AC power interruption
The Starplus VC61106 BCU is designed for use with the DHS system. Follow the 
instructions supplied with the BCU to install batteries in that unit. Consult Table 2-11 for 
system operating current draw to select the right battery size for the desired back up 
duration.
The ground wire should be kept as short as possible and can be connected 
to the ground lug located on the bottom of the KSU. Check your local 
grounding regulations before installing the ground wire.

Cautionary Steps
To reduce the risk of fire or injury to persons, read and follow these tips:
†Use only the following type and size battery(ies) listed here as the maximum battery 
type and size: 24vdc, 40 AH.
†Do not dispose of any battery(ies) in a fire, the cell may explode. Check with local 
codes for possible special disposal instructions.
†Do not open or mutilate the battery(ies). Released electrolyte is corrosive and may 
cause damage to the eyes or skin. It may be toxic if swallowed.
†Exercise care in handling batteries in order not to short the battery with conducting 
materials such as rings, bracelets, and keys. The battery or conductor may overheat 
and cause burns.
†Charge the battery(ies) provided with or identified for use with this product only in 
accordance with the instructions and limitations specified in this manual.
†Observe proper polarity orientation between the battery(ies) and battery charger.
†Do not mix old and new batteries in this product (applies to products employing 
more than one user replaceable secondary battery).
Do not mix batteries of different sizes or from different manufacturers in this product 
(applies to products employing more than one user-replaceable, secondary battery).
4. KSU Installation 
The KSU is designed for wall mounting only. The KSU should NOT be mounted directly on 
a masonry surface. If the KSU is to be mounted on a masonry surface, a wooden 
backboard of sufficient size should be attached to the wall and the KSU mounted on the 
backboard.
1. Using the mounting template as a guide, mark the 2 mounting screws locations on 
the MDF backboard.
2. Pre-drill 2 screw holes and install 2 pan-head No. 10 screws into the backboard. The 
screw heads should protrude about 1/4-in. from the backboard plywood surface.
3. Lift the KSU over the 2 screws allowing the screws to extend into the KSU slotted 
mounting holes. As the KSU is allowed to rest in place on the mounting screws it will 
slip over the screw shanks until the top of the slot is reached. Properly installed, the
