9 INSTALLATION 9.1 INTRODUCTION As with any sophisticated communications device, installation of the Aria-16/20 System requires the care and forethought of a competent technician. Installation proceeds in 4 major steps: -. Site Preparation -. KSU Installation -. PCB Installation -. System Wiring WARNING WARNING: THIS EQUIPMENT MUST ONLY BE INSTALLED AND MAINTAINED BY AUTHORISED SERVICE PERSONNEL.

9.2 SITE PREPARATION 9.2.1 General Site Considerations The first step is to locate an acceptable site for the common equipment.(KSU, boards, etc.) When locating a mounting site for the system, the following points must be considered: 1.

The KSU is designed for wall mounting and should not be mounted directly to a masonry or plasterboard wall. It is recommended that a ½ inch thickness plywood backboard be firmly mounted to the wall first, and then the KSU mounted on this back-board.

2.

The location must have access to 240 Volt AC, 50 Hz with a circuit breaker or fuse rated at 15 amps. A grounded outlet (GPO) should be within approximately 2 meters (6 feet) to ensure the shortest power cord possible.

3.

The location must have access to a good earth ground, such as a metallic cold water pipe with no non-metallic joints. The ground source should be located as close as possible to the system. It is recommended that the installer tests the integrity of the earth for the GPO.

4.

The system should be located in an area which is well ventilated with a recommended environmental temperature of 20 - 26 degrees C (68 - 78.8 degrees F) and a relative humidity of 5 85 % (non-condensing).

5.

The system should be located within 8 meters (25 feet) of the telephone carrier‟s termination point (MDF). Also, the location should be within the prescribed station loop lengths for all keysets and terminal equipment, including ISDN and SLT extensions. If existing cabling is to be employed, the location and integrity of existing cabling and conduits should be carefully considered.

6.

The location should have adequate accessibility, space and lighting for future servicing and should consider the need for future expansion.

7.

The site should be away from radio transmitting equipment, arc-welding devices, copy machines, and other electrical equipment capable of generating electrical interference. The system should be protected from flooding and heavy machinery as well as excessive dust and vibration.

263



9.2.2 Back-Board Installation A wooden backboard is recommended for all installations and must be installed when the location has masonry or plasterboard walls. A ½ inch plywood material is sufficient for most installations. The backboard should be mounted at a convenient height, about 1 meter above the floor, and be bolted in two places to distribute the weight of the system sufficiently.

9.2.3 Verify On-Site Equipment Once the equipment installation site has been identified, dedicated earth ground established, lighting, ventilation and environmental conditions are suitable, verify that all equipment required is on-site and has not been damaged during shipment. Note that a mounting template is packed with each KSU and this template will be required for the location of mounting screws for the KSU. Check that the type and quantity of boards received is correct and optional equipment is on-site. If any equipment is damaged or missing, notify appropriate personnel to correct the situation and satisfy the customer.

264



9.3 KSU & POWER INSTALLATION The Aria-16/20 system consists of a plastic KSU and a number of optional expansion boards. The exterior view of the Aria-16/20 is shown in the following figure.

Aria-16/20 Exterior View

265



9.3.1 Mounting the KSU The KSU is a plastic frame cabinet designed for wall mounting. Employing the KSU mounting template provided with the KSU, mark the location of the two screws to mount the KSU. Again, the KSU must not be mounted on a masonry or dry-wall surface, in this case a wooden backboard is required, refer to paragraph [BackBoard Installation]. The distance between mounting holes is shown in the following figure. The KSU is mounted using two #10 or larger, 1.5 inch or longer screws. First, drill pilot holes in the two locations marked, insert the screws and tighten leaving about 0.5 inch exposed. Hang up the KSU on the screws and tighten.

9.3.2 Power Connection The Power Supply Circuit of the MBU provides power for the system boards and telephones, converting the AC Input Voltage to appropriate DC voltages required for system operation and board logic levels. Before installing the KSU, and prior to connection of the communications network ensure that the AC power cord is NOT plugged into the AC INLET. During board installation or changes to network connections the AC power cord MUST be plugged into the GPO and turned OFF. The Power Supply Circuit is located on the left upper side of the MBU. The Aria-16 Power operates on 240V AC based on the connection of the cable (4-wired) by the CN16 from transformer and the connection of the cable (2-wired)by the CN17 to transformer

9.4 PCB INSTALLATION 9.4.1 PCB Handling & General Installation All boards should not be installed or removed with power applied. Power must be turned off prior to insertion or removal of the PCB. The system PCBs contain digital circuitry that can be damaged by exposure to excessive static electricity. When handling the PCBs, a grounded wrist strap should be used to protect the boards from static discharges. Also, use common sense applies when handling the PCBs. For example, do not place a PCB directly on carpet or in locations where heavy objects might fall on the PCB and damage components. Similar precautions must also be taken when installing or changing system EPROM or other associated memory devices (chips). Care must be taken to ensure chip orientation, location and type are correct. An anti-static wrist strap with earthed ground mat should also be used. To insert a PCB, hold the PCB by the edges and, with component side facing right, insert the card into the MBU‟s connector firmly. To remove a PCB, reverse the procedure. Installation method of PCB is shown in the following figure.

PCB Installation There are 5 slots in the Aria-16/20 system for extending or modifying the system configuration. However there are some restrictions when installing the optional boards. Note that the system will not operate properly and damage will occur with incorrect board installation. SLOT1 of the MBU is reserved for LCOB2, LCOB, STIB2 or STIB. SLOT2 is reserved exclusively for the DVIB. SLOT3 & SLOT4 are reserved for either the SLIB or DTIB card or DSIB (Aria-20 only) and SLOT5 is for MFB only.

9.4.15 DTMF and Pulse Type SLT with Aria-16 SLT ports on MBU and SLIB With the Aria-16/20, the SLT port type is automatically detected and saved after power on according to the type of the first digit detected from the SLT. After the Aria-16/20 is powered ON, all the SLT ports on MBU and SLIB are initialised with PULSE(DECADIC) type. The Aria-16/20 is waiting for a digit from an SLT port. If a DTMF digit is detected then Aria-16/20 changes the SLT type designation to DTMF type. If a pulse (decadic) type digit is detected, the Aria-16/20 holds this SLT type as initial value PULSE type. The SLT port type is saved into Non-Battery Backed up memory area. So, when Aria-16/20 power off and on, then boot-up SLT detection step is repeated. When SLT type is DTMF type, minimum Hook Flash time is 50 mseconds (fixed value. This time is not programmable.), and maximum Hook Flash time is Hook Switch Time + 60 mseconds. A Break signal longer than maximum Hook Flash time is detected as On-Hook condition. Hook Switch Time is programmable by admin programming. When SLT type is PULSE type, minimum Hook Flash time is 94 mseconds (fixed value. This time is not programmable.). A Break signal shorter than minimum Hook Flash time is regarded as pulse to detect pulse (decadic) digit. The maximum Hook Flash time is Hook Switch Time + 60 mseconds ( same as DTMF type SLT). A Break signal longer than maximum Hook Flash time is detected as On-Hook condition. Hook Switch Time is programmable by admin programming. When you change DTMF type SLT (after use) to PULSE type SLT during power ON condition of Aria-16/20, then pulse digits from PULSE type SLT is not detected. A 60 msecond or 66 msecond Break signal from PULSE (DECADIC) type SLT is not detected as a pulse, and is detected as a Hook Flash for Aria-16/20. The system regards this port SLT as DTMF type, so Break signal longer than 50 mseconds (minimum Hook Flash time) is detected as a Hook Flash. You can not make call from PULSE type SLT. However when you turn power OFF and the ON again, then you can use PULSE (DECADIC) type SLT. When you change PULSE (DECADIC) type SLT (after use) to DTMF type SLT during Aria-16/20 power ON condition, then DTMF digits from DTMF type SLT is detected and Aria-16/20 changes this SLT type to DTMF type. So you can use DTMF type SLT after PULSE (DECADIC) type with-out power restart. Please note that a mixture of SLT types can not co-exist on the same system. DTMF and PULSE (DECADIC) type SLT are mutually exclusive. SLT port behind 2B module with SLIU When power on start, MBU sends SLT port type to 2B module with SLIU as soon as MBU detects that 2B module is with SLIU. Then the 2B module detects digits from its SLT port according to the type of SLT from the MBU. If MBU sends DTMF type, then 2B module detects only DTMF type digits. Aria-16/20 sends DTMF type to 2B module with SLIU as soon as Aria-16/20 detects that 2B module is with present. When using the SLIU with Aria-16/20 it does not have any pre-determined SLT port type. This means that with Aria-16/20, 2B module with SLIU will only support DTMF type SLT. Note: Other Aria systems have an admin program field for SLT port type. You can use PULSE type SLT with 2B module with SLIU, after set this port as PULSE type, then other Aria‟s send PULSE type to 2B module as soon as other Aria‟s detect that 2B module is with SLIU.

9.5 SYSTEM WIRING 9.5.1 Battery Back-Up Wiring Installation The system can be equipped with external batteries for continued operation when the local AC power fails. The Back-Up batteries are connected to connector (CN3) of the MFB. The cable assembly used between the batteries and the KSU (MFB) are not supplied by the distributor. The installer must supply these cables. The External batteries must provide 24 Volts DC. This is generally accomplished by connecting two 12 volts batteries in a series arrangement. Battery operation is controlled by the MFB. The MFB will provide charging current (maximum 0.5 amp) to the batteries during normal AC power operation. The MFB will automatically stop the battery power application when AC power is re-applied or low battery supply voltage detected. The system operating time from Battery Back-Up batteries is dependent on several elements such as battery charge state, condition of the batteries, capacity of the batteries, and the system configuration (number of station ports). Battery Back-Up is connected to the connector(CN3) of the MFB, as shown in following figure.

Battery Back-Up Wiring

Warning : - Carefully check the battery polarity with cable colors when connecting the battery to the system. Damage will result if battery is connected incorrectly. - A fuse (5A @250V) must be used between battery and system. - Recommended battery capacity is 24V/10AH MF battery. The system will operate more than 5 hours with this battery.

9.5.3 ISDN extension (S0 interface) Wiring (STIB, STIB2) ISDN extension connection, is realised by using an RJ45 terminated ISDN patch cord on the ISDN „S‟ interface ports (STIB2, STIB). Terminating resistors are required when operating in the „S‟ mode (ISDN extension connection). The terminating resistors are enable by turning DIP switch 3 (SW2) ON for STIB, and DIP switch 3 (SW2) ON for STIB2 port 1 and DIP switch 4 (SW2) ON for STIB2 port 2. A ferrite core is to be fitted to this cable for EMI suppression. An ISDN patch cord is provided for connection of the Aria-16/20 to the MDF. The installer is to provide the KRONE insulation displacement/RJ45 type termination points at the MDF.

9.5.4 ISDN trunk (‘T’ interface) Wiring (MBU, STIB, STIB2) ISDN extension connection, is realised by using an RJ45 terminated ISDN patch cord on the ISDN interface ports.(STIB2, STIB, MBU). The Aria-16 provides for connection of up to three (3) ISDN (2B+D) services. These services can be connected to the MBU ISDN port, the STIB (in „T‟ mode), and the STIB2 (in „T‟ mode) ports. A ferrite core is to be fitted to this cable for EMI suppression. An ISDN patch cord is provided for connection of the Aria-16 to the MDF. The installer is to provide the KRONE insulation displacement/RJ45 type termination points at the MDF. Terminating resistors are not required when operating in „T‟ mode (network connection).

9.5.5 PSTN trunk Wiring (LCOB, LCOB2) The Aria-16 supports a maximum of four (4) PSTN trunk ports by using either LCOB or LCOB2 expansion boards. Connection to these cards will be via CAT5 UTP cable terminated on the MDF, which will be in close vicinity of the KSU. UTP cabling is to be provided by the installer.

9.5.6 Digital Key Telephone (keystation) Wiring The Aria-16 supports connection of Digital Key Telephones to either the basic MBU DKTU ports or DTIB expansion cards. Connection to these DKTU ports will be via CAT5 UTP terminated on the MDF. UTP cabling is to be provided by the installer.

9.5.7 Single Line Telephone (analogue) extension Wiring The Aria-16 supports connection of Single Line Telephone (analogue) devices to either the basic MBU SLT ports or SLIB expansion cards. Connection to these SLT ports will be via CAT5 UTP terminated on the MDF. UTP cabling is to be provided by the installer.

9.5.8 Music on Hold (MOH) Wiring The Aria-16 System can send internal or external music signal to CO lines and extensions that are in hold state. The default music source input is assigned to the internal source. The external music source can be used by changing the system programming database and connecting an external music source to the blue colored terminal block (CN22 pin#5,6) of the MBU. This contact is labeled accordingly on the MBU. Note: An approved MOH (Music On Hold) LIU must be installed when connecting an external MOH source to the system.

9.5.9 General Purpose Relays Wiring There is a general-purpose relay on the MBU and these contacts are connected through CN22 pin#1,2 (RELAY1) of the MBU. The control of these relays are configured by system database programming. There is also a general-purpose relay on the MFB and these contacts are connected through pin#1,2 (RELAY2) of the MFB. These dry relay contacts can be used for Loud Bell Control function, Door Open function, etc. under software control. Note that the maximum rating of the relay contact is 30Volt/3A. Care must be taken not to use these contacts over this rating or damage will occur to the equipment.

An approved LIU must be installed when connecting an external device to the alarm detection port of the system.

9.5.11 Mains Power (240Vac~50Hz) Wiring The Aria-16 KSU is supplied with a 3-pin power cord. The Aria-16 KSU has no separate power switch. Power ON/OFF condition is realised through turning general power outlet switch ON/OFF and removing power cord from KSU and GPO. The system protective earth (P.E.) is obtained from the power cord connection. Please note that by removing the power cord from the GPO the system earth is also removed. Network connections must be disconnected prior to removing the power cord from the appliance coupler or GPO. The integrity of the protective earth system must be re-established before making any network connections for electrical safety reasons.
