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.

Installation
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.

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.

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.
