DCS 24 MARCH 1999 INSTALLATION MANUAL

1 SITE REQUIREMENTS

The installation site for the Samsung DCS, DCS 70, DCS 24 and DCS Compact Systems should meet the following requirements -

• The location for the key service unit (KSU) must provide enough space for easy installation and have adequate lighting. The DCS 24 KSU Key Service Unit measures 46.5cm high by 31.5cm wide by 12cm deep.

• Select a location that will minimize cable lengths. See the maximum cable length limits in Chapter 6.

• The equipment should not be exposed to moisture, direct sunlight, corrosive fumes, dust, constant

vibration or strong magnetic fields such as those generated by motors and copy machines.

• A single phase, correctly earthed, 240V, 10Amp, 50Hz, AC General Purpose Outlet (GPO) must be provided within two metres of the KSU. The GPO must be easily accessible and kept clear of obstructions. Extension cords must not be used. A dedicated, separately fused circuit should be used to minimize the risk of other electrical equipment being connected that could adversely affect system operation.

• Ensure that all wires and cable going to and coming from the KSU are properly routed. The cables should not cross fluorescent lights or run parallel with AC wires.

• The equipment must be located in an environment that will remain within the Temperature range of 0oC to 45oC and 10% to 95% Relative Humidity, non-condensing.

• Allow at least 30cm clearance on both sides and 30cm clearance on top of the KSU to ensure proper ventilation. Refer to Figure 2.1

• Do not install the KSU in close proximity to a fire sprinkler head or other sources of water.

Meeting these requirements will help to ensure proper performance and greater life expectancy of the system.

Immunity to Interference.

The DCS, DCS 24, DCS 70 and DCS Compact Systems

have been designed to be immune to the levels of

interference normally found within residential and

commercial premises (for example, mains dips and

breaks, electro-static discharge, overvoltages and

transients, electromagnetic fields).

It is the customer’s responsibility to provide an environment for the DCS systems, Keysets and cabling that does not contain excessive sources of interference that could affect the operation of the systems.

NOTICE

Note that the Samsung DCS 24 system should only be installed by fully trained

and qualified personnel.

2 INSTALLING THE BASIC KSU

2.1 SYSTEM CONFIGURATION AND CAPACITY

The

DCS-24

Interface modules and Digital k eysets. The initial configuration of two (2) analogue C.O. line ports and 16 station ports: twelve (12) k eyset ports and four (4) SLT (single line telephone) ports. The Basic Key Service Unit (KSU) contains one (1) Trunk Expansion slot, two option card connectors for fitting one serial interface cards, connections for an optional AA card and miscellaneous circuits: one (1) External Page Interface, one (1) general-purpose dry contact and one (1) Music interface selectable to Internal built-in Music (a Melody chip) or External Music.

Two types of telephones can be connected to the system: proprietary digital stations – DCS k eysets that connect to DLI (Digital Line Interface) ports, and standard telephone s ets – Single Line Telephones that connect to SLI (Single Line Interface) ports.

The Trunk Expansion slot has the provision f or installation of an Analogue trunk card or an ISDN Basic Rate card.

The DCS-24 system also has capacity for the fitting of Option boards to provide Serial I/O ports, an analogue Caller ID (FSK) decoder or AA facilities. The 24SIM card provides 2 serial ports ( 2RS232C) for connection to a PC, printer or modem. The 24SIMCID provides an 8 channel CID signal decoder in addition to the 2 serial ports provided on the 24SIM. The AA option board (24AA) is equipped with a 4 channel Auto Attendant.

The Key Service Unit (KSU) basic configuration is 2 analogue trunk ports and 16 ex tensions ( 12 digital, 4 SLT); the maxim um capacity is achieved by installing the 4BRI card in the trunk expansion slot – this configuration provides 10 trunk ports (2 analogue exchange lines and 8 BRI channels) and 16 extensions. Lesser trunk capac ities of 4 and 6 ex change lines respec tively are achieved by installing the 4TRKCID or 6TRKCID cards.

system consists of the Basic Key Service Unit (KSU), Option boards, Tr unk Interf ace cards ,

DCS 24 MARCH 1999 INSTALLATION MANUAL

2.1.1 CONFIGURATION NOTES

1. The DCS 24 does not provide f or installation of Keyset Daughter-Boards for additional DLI or SLI expansion.

2. Only one (1) trunk expansion card (4BRI-C, 4TRK24 or 6TRK24) is possible.

3. Capacity is provided for the installation of one SIO option board (SIM24) and one AA option board (AA24).

4. The system cannot accomm odate any cards from other Sam sung Digital Systems except for the DCS Compact BRI card (4BRI-C).

5. The Analogue Caller-ID presentation facility requires installation of the in addition to an analogue trunk card (a 4TRK24 or a 6TRK24). This facility will not be activated for the two analogue trunk lines connecting to the Basic KSU.

6. Every analogue trunk interfac e contains an interface for MPD or PRS modules (these are the same as those used on the DCS).

2.2 UNPACKING AND INSPECTION

After unpacking the KSU, inspect f or any signs of physical damage. If any damage is detected, do not attempt to install. Contact the local distributor for advice.

Check to see that the Basic KSU carton includes the following items.

! Basic Key Service Unit (KSU) ! AC Power Cord ! Wall-m ount kit consisting of mounting bracke t, cable ties, 4 screws, battery connection cable and

spare fuses

! SLT User’s Guide (Standard telephone)

2.3 MOUNTING THE KSU

(See Figure 2-1) The DCS-24 must be wall-mounted in a vertical position. The KSU should be mounted on a section of the wall capable of holding the weight of the system (approximately 5 Kg fully loaded) and cables eg close to a stud or noggin. Attach the wall-mount bracket to the backboard with screws supplied and hang the KSU on the bracket.

2.4 PROTECTIVE EARTHING

The protective earth connection to the DCS 24 is provided via the three core mains lead. The earth wire in the mains cord (Green/Yellow) is connected in the factory to the earth terminal within the system. The Earth wire is connected directly to the bottom left hand corner of the Power Supply case

The protective earth (PE) is used for surge protection and for the electrical safety of the system. The system must be plugged into a GPO socket that is correctly earthed. The PE provides all system earthing requirements, a TRC is not required and should not be connected.

WARNING

The equipment, users and service personnel must be protected against possible surges of current down exchange lines. This must be done using one, or both, of the following methods when installing or working on the system -

• Plug the mains lead into the GPO socket, ensuring that the socket is turned off.

• Isolate the exchange lines from the system. This may be done by isolating the lines at a distribution

frame.

The Power Supply has fuses in both the mains active and neutral legs, therefore caution should be used when working on or near the power supply. Turn OFF the power supply switch on the KSU before working on the system.

INSTALLATION MANUAL

2.5 DISTRIBUTION FRAME CABLING

All connections to the DCS-24 system are made by way of a customer – provided system distribution frame (SDF). All c onnections are m ade via the SDF exc ept for the ser ial data ports, 240VAC m ains and the battery back up.

The KSU is connected to the SDF using a 25-pair male AMP Champ cable and a 4-pair m odular plug (RJ-45) plus cable (for connection of Single Line Telephones. The c ables should be routed into the KSU cabinet via the bottom of the cabinet and clamped to the c able anchoring point using a nylon cable tie. The retaining screw on the AMP Champ connector should be used to hold the connector in place.

Details of the cable connections are in Section 5.

2.6 EXTERNAL BATTERY CONNECTION

See (Figure 2-3) A socket is provided on the KSU for c onnection of an external battery for system during AC power f ailur e. The DCS-24 system is equipped with a battery charging and a discharging circuit to interface with an external battery.

The capacity of a backup battery must be 48 volts and should be rated at greater than 6AH and less than 26AH. The DCSBBU backup battery is rated at 7AH.

To connect an external battery use the connection plug and cable supplied, and connect the RED wire lead of the cable to the positive (+) term inal of the battery and the BLACK wire lead to the negative (-) terminal. The plug should be inserted into the socket in the power supply.

Note that the actual connection should be done as the final step in the installation process.
