Comdial Unisyn System Manual

							System OverviewIMI64-1121.4.3 Knowing The Stations
You can install many different types of telephone stations, either proprietary Unisyn electronic
microprocessor-controlled devices, or industry standard, 
(IST) telephones like the 2500. The stations provide users
with not only multiline pickup but also single button access to features available from the serving CO, PBX, or
CENTREX switch and common equipment.You can program each telephone station to have a unique set of
features and operating parameters 
(see Chapter 3.7). All currently produced Unisyn telephones will work with the
Unisyn system, as will any industry standard telephone, or accessory such as a facsimile machine or modem, (with
‘TM[ST board). Figure 1.4 shows a typical station’s mounting dimensions, and figure 1.5 shows all of the av&.d.de
telephones.
You can install all of the following:.
Proprietary Multiline Unisyn Telephones
1022s-xx
1122s~xx
1122x-xXl
Industry Standard Telephones-including any Analog Device (facsimile machine, modem)
You must have a TXIST board for IST support..
Four-conductor twisted-pair cable (used for multiline station connections).l
Two-conductor twisted cable (used for single line IST station connections).
NOTE: Any industry-standard device should be fully compatible with a 24 V battery. feed.We also recommend
that 
ISTs have the TAP (Flash) and Positive Disconnectfeatures to have &cess to system features and to
prevent false 
signuling.

							Installing The Unisyn System
:::. .,..:.:: ,\.::
2. I Using Chapter Two
Chapter two provides you with a step-by-step procedure for installing the Unisyn System. We have presented the
information in the 
most common orderfor instdution and recommend that you follow the manual when installing.
Always do a pre-installation check to make sure you have the necessary equipment and documentation.
Use the following list as a general guideline for installing the system. This list is by no means the only possible order
for installation.
1.Unpack the system and read through this manual
2. Select the correct tools (2.2)
3. Install any option boards into the common
equipment (see corresponding publication(s))
4.Mount the cabinet in a suitable location (2.3)
5.Mount the punch-down blocks and any
auxiliary equipment
6. Mount the battery backup, but don’t connect
the battery (2.4.2)
7. Wire earth-ground to Common Equipment (2.4.3)
8. Wire the CO Lines to the Common Equipment(2.5)
9. Wire-station connector to Common Equipment
(2.6)
10.Wire the stations to the station connector (2.6)11. Connect auxiliary equipment-for
example, music interface, or data device (2.7)
12. Inspect all wiring (2.8.1)
13. Check DC resistance of stations and lines to
ground (2.8.2)
14. Power-up system (AC); check green LED (2.8.3)
15. Check DC voltages of stations (2.8.4)
16. Check Battery and Battery Charger DC voltages(2.8.5)
17. Connect Battery Backup (2.4.2)
18. Master clear the system (3.4)
19. Check default functionality (2.8.6)20. Program the system
“...,2.2 Using The Right Tools
As a minimum, the tools and hardware required for installation include the following:
0Fasteners-wood screws (*/4 x l-inch round head), toggle bolts, or wall anchors
0 Screwdriver-to match fasteners
0 Electric drill-if prepared holes are required
j-JConnecting tool-for fastening wires to a type-66 connector block
[I3Crimping tool-for 623-type modular plugs
qVolt-Ohm Meter-for testing power source, CO Lines, and Stations2-l

2.3 /nsta//ing The Cabinet
Before you mount the cabinet, consider the following list in the layout and connection of the telephone system.It
might be helpful to put a check-mark in each box as you complete that task.
0Attach the common equipment cabinet vertically to any sturdy flat surface. You may vertically rack-mount the
system.
0Locate the cabinet within four feet of a proper electrical outlet. The system requires a dedicated 117VAC
15 AMP circuit, with a third-wire ground, supplied to a standard electrical outlet 
(NEMA 5- 15R).
0FCC requirements state that the distance between the common equipment and the TEZLCO/PBX jacks must be
25 feet or less. We recommend that you use a nominal distance of 7 feet.
0Make sure the mounting location is secure and dry and has adequate ventilation. The temperature range of the
location must be within 32 to 122 degrees F (0 to 50 degrees C), and the relative humidity must be less than 90
percent non-condensing.
0If the mounting surface is damp or if it is concrete or masonry material, attach a backboard to the mounting
surface to be used for common equipment mounting.Suitable mounting backboards are available commercially
or can be constructed out of 
l/2-inch plywood cut to size.
0If you choose to install battery backup, install the optional external batteries, cable assembly, common
equipment, and the wiring connections in a dedicated equipment room-except for 
BBLO2 (as defined in the
NationaZ Electric Code published by The National Fire Protection Association, Quincy MA, 02269).2.3.1 Mounting The Cabinet
1.Unpack and carefully inspect all equipment for shipping damage. Notify the shipper immediately of any
damages. Verify that the packages contain all parts and accessories needed for proper installation and operation.
2.If you use a backboard at the mounting location, attach it securely to provide a stable mounting surface for the
equipment.
3.Mark the locations for the screws on the mounting surface (see step five for the mounting dimensions).
4.Drill holes in the mounting surface of a proper size to accommodate the hardware being used. If necessary,
prepare these holes with inserts, anchors or other attachment devices as dictated by the type of mounting.
