STARPLUS 1224EX KEY TELEPHONE SYSTEM 
500 lNST’ALlATlON 
500.1 SITE PLANNING 
The STARPLUS 1224EX Electronic Key Telephone 
System, like most electronic office equipment, 
should not be subjected to harsh environmental 
conditions. To assure easy servicing and relhble 
operation, several factors must be considered 
when planning the system installation. Always 
consider the following BEFORE installing the KSU 
and wiring: 
A. The KSU is designed for wall mounting only. 
B. The internal power supply operates with 117 
VAC, 66 Hz, single phase electricity. A 3-wire 
(parallel blade with ground) receptacle must be 
provided on a dedicated, separately fused 15 
AMP circuit. 
C. Location(s) of tdephone conduits or cable 
runs. 
D. The KSU should be within 25’ of the 
telephone company FlJ21 X. The KSU should be 
centrally located and assurances should be 
made to stay within prescribed cable lengths. 
. 
500’ 26 AWG twisted pair 
i 1000’ 24 AWG twisted pair 
. 1500’ 22 AWG twisted pair 
E. A well ventilated area having a recommended 
temperature range of 70-76 degrees F and a 
humidity range of 5-86% (non condensing). 
F. Lighting and accessibility of KSU for servic- 
ing. 
G. Protection from flooding, flammable 
materials, excessive dust and vibration. 
H. Proximity of radio transmitting equipment, 
arc-welding devices, copying machines and 
other electrical equipment that are capable of 
generating electrical interferences. 
I. Access to a good earth ground such as a 
metallic COLD water pipe. Inspect the pipe for 
non-metallic joints. 
500.2 UNPACKING THE KSU 
Remove the KSU from the shipping carton and 
place it on a level working surface, face up. In- 
spect the KSU for physical damage. 
500.3 KSU GROUNDING ” 
TG ensure that the system will operate properly, 
a good earth ground is recommended. A metal- 
lic COLD water pipe will usually provide a rell- 
able ground path. Carefully check that the pipe 
does not contain insulated joints that could isc- 
late 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. 
THE GROUND WIRE SHOULD BE KEPT AS 
SHORT AS POSSIBLE AND SHOULD BE CON- 
NECTED TO THE GROUND LUG LOCATED ON 
THE EOITOM OF THE KSU. 
50th KSU INSTALLATION 
A. The KSU is designed for wall mounting 
only It should not be mounted directly on a 
masonry surface. 
If the KSU is to be mounted on a masonry sur- 
face. a wooden backboard of sufficient size 
siiol;fd be attached to the 
wall and the KSU 
rot nted on the backboard. 
B. E lount the KSU on the backboard using 4 
kxr >ers. (The fasteners should be selected 
,:::rerully so as to be capable of supporting 
:he h3l.f). Refer to Figure 5.1 for KSU dimen- 
ffons 
C. install the ground using an insulated 8 
AWG =opper wire. 
Attach one end to the 
c:rounrl lug on the KSU cabinet and the other 
erd to a good earth ground. See Figure 4.2. 
D. The KSU power supply is located within 
the KSU and all electrical connections are 
provided externally. The AC power cord exits 
tt. z KSU on the bottom. 
AI .:I on the bottom is a fuse holder that con- 
ta 3 a 1.5 Amp slow-bfow fuse. 
P:, dar for the system is distributed internally. 
0  
						

							STARPLUS 1224= KEY TELEPHONE SYSTEM 
E. The AC power cord should not be used with 
a 3-wire-to-2wire plug adapter. Do not use ex- 
tension cords. 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 
manufacturer’s instructions and applicable 
electrical codes. 
WAFiNING: DO NOT PLUG IN THE POWER CORD 
AT THIS TIME. 
500.5 KSU CABLING 
Four amphenol type connectors are provided on 
the left side of the KSU. The male connector called 
P-i is for the 12 CO lines. Also on the left side of 
the KSU are 3 female connectors labeled J-l, J-2 
and J-3. These connectors require male ended 
plug cables for proper attachment. 
When connecting cable tails to the KSU, make sure 
the designation on the AMP hood matches the 
designation at the connectors input on the KSU. 
After plugging in the required cabies, a “horse 
shoe” fastener should be placed around the mated 
AMP connectors to secure the cable to the KSU 
connector provided. 
Verify that the wires are properly cross-connected. 
Observe telephone standard wiring color codes 
wherever necessary. See Figure 5.2. 
Cabling should be routed to avoid fluorescent light 
fixtures, electric motors and generators, welding 
equipment and radio transmitters. Afso, care 
should be taken to avoid hot locations such as 
steam pipes and furnaces, and areas where wiring 
is subject to abrasion. 
CAUllON 
It is NOT recommended that AC power be applied 
to the system during the cable termination 
process. 
500.6 LIGHTNING PROTECTION 
The 1224 should have central office lines protected 
with proper lightning surge arrestors. The central 
office lines are exposed to damaging surges in- 
duced by direct or non-direct lightning strikes. The 
protection should contain a complement of 3-eie- 
ment gas discharge tubes which ground high 
potential surges and associated circuits to absorb 
and filter lower-level surge potentials. Care should be taken to ensure that not more than one set 
of protectors be installed on central offfce lines 
at installation premises. Improper installation of 
line protectlon can present a serious safety 
hazard. 
566.7 KEY TELEPHONE INSTALlA- 
TION 
A maximum of 24 key telephones may be in- 
stalled with the 1224 key system. Each key 
telephone requires 2 pair (4 wires) for proper 
wiring. It is required that 
3 pair twisted cabie be 
used to connect the telephones to thesystem 
on a 8’home run” basis. The teiephone end of 
the cable should be terminated on a modular 
jack. At the MDF end of the home run, the cable 
should be terminated on a separate station con- 
necting Mock (S6Ml-50) for cross connection 
to.the “J” cables. This method of cabling will 
allow for easy isolation of station equipment 
during trouble shooting procedures. 
500.8 WALL MOUNT KIT INSTALlA- 
TION 
All connections to the key telephones are fully 
modular. To wall mount the key telephone, it is 
necessary to have one Wall Mount Kit and one 
630-A type modular wall mount jack assembiy 
equipped with 2 mounting lugs. 
A. Remove the mounting cord from the 
telephone. This cord will no longer be 
needed but should be retained for main- 
tenance purposes. 
B. Substitute the short modular cord on the 
wail mount baseplate for the mounting cord 
removed in A. 
C. Rotate the plastic number retainer up- 
wards to expose the screw underneath. 
Remove the screw and slide the cover plate 
under the number retainer towards the hook 
switch. 
D. Replace the cover piate with the handset 
retainer tab that is mounted in the wall mount 
baseplate and secure with the screw from C 
above. 
E. Rotate the plastic number retainer 
downward and snap into place. 
F. Align the mounting tab on the outer edges 
d the wall mount + with the hdes on the 
key telephone base. Snap shut and fasten 
with the screw.

G. The telephone can now be mounted to the 
wail by matching the 2 keyhole slots on the 
baseplate with the lugs on the modular cover as- 
sembiy. Check to make sure that the modular 
connector on the baseplate is firmly connected 
to the wall jack. 
500.9 PHONE BOX INSTALLATION 
The 1224 Phone Box can make calls to preas- 
signed stations as well as receive intercom calls. 
The unit should be located in weather protected 
areas where paging or monitoring is required. 
The Phone Box consists of a top housing and bot- 
tom mounting plate. The top housing has a 
speaker microphone, wire terminals and electronic 
circuitry. The housings are separated by inserting 
a thin, flat-edged tool at the bottom rim of the as- 
sembly. By pressing inward on the recessed 
retaining tab, the assembly will open. 
The connection of the Phone Box@) to the KSU 
is identical to that of the key telephone. Refer to 
Section 500.7. 
The bottom plate of the Phone Boxassembly isfas- 
tened to the wail by mounting with customer sup 
plied No. 8 or larger pan head screws. The cable 
is routed through the cable-entry hdes provided 
on the bottom plate and is connected to the screw 
terminal strip on the upper housing. Four screw 
terminals are Identified by wire color on the 
silkscreened printed circuit board to correspond 
with the wiring sequence at the punchdown con- 
nector at the MDF. 
The slack wiring should be pulled back through the 
bottom mounting plate and the top housing 
snapped shut. Refer to Section 600.6 (statlon 
class of service) to program phone boxes. 
WARNING: Make connection at the phone box 
before punching down on the MDF. 
500.10 DSS/BLF CONSOLE INSTAL- 
LATION 
Each DSS/BLF requires 2 pair (4 wires) for proper 
installation. Three-pair twisted cable is recom- 
mended to connect the DSS/BLF units on a “home 
run” basis. Each DSS/BLF must be used together 
with a key telephone, therefore a maximum of 12 
units can be used in the system. Refer to the 
programming instructions. 
Em1 1 EXTERNAL MUSIC SOURCE 
Music-on-hold as well as Background -music 
can be connected using a customer provided 
,nusic source. Separate Music-On-Hdd and 
background music volume adjustments are 
provkfd on the KSU. (Figure 4.2). 
Background music (BGM) levels are also adjus- 
table at each key telephone set. Connections 
are made on the J-8 connector, the MOH pair. 
See Table 5-8. 
500.12 ALARM INSTALLATION 
An alarm signal can be transmitted to each sta- 
tion (except phone boxes) in the system. When 
activated by an external alarm system, a con- 
tinuous or repeated tone is transmitted to the 
&tron speakers. Leads from the external alarm 
are cxmctad to the J-3 terminals ALMT and 
ALMB ,.,Figure 5.5). See Section 600 for 
programming alarm states. After the alarm has 
sounded, rhe system must be reset by first clear- 
ing the a&m condition on the extemai system 
and [hen lifting the handset an any station 
programnied to receive alarm and dialing ‘9”. 
500.13 EXTERNAL PAGING 
An amplifier for external paging can be con- 
nected to the 1224 key telephone system. Any 
teiephone in the system can access this paging 
equipment by using a dial code. There is one 
External Paging Zone (without amplifier) 
provided in the 1224 system. 
The output impedance of the paging zone is 600 
Ohms. The low level voice signal output is 
specified at 5 milliwatts. Dry contact control is 
provided to switch on the external amplifier 
equipment or to momentarily remove back- 
ground music, if externally supplied to the 
paging device. All connections are made on the 
J-8 punchdown connector. The voice output 
from the key telephone system is provided on 
the EPVT and EPVR pair. The “make” contacts 
are Mentified as pair EPCTL The paging port 
can be connected to a two way paging system.

Ill. INSTALLATION 
A. Introduction 
See Figure 5.8 for the location of the input socket. 
The input socket of the key system must be a 
female Mate-N-Lok type connector. 
B. Installation Checklist 
The following items are required to install the BBU: 
- 1 BBU with wire kit (5 wires) and tlewrap 
- 4 No. 12 panhead screws (if wall 
mounted) 
- Screwdriver 
- Backboard or wail shelf if applicable 
C. Mounting 
The BBU must be located within 6’ of an AC recep- 
tacle and 2’ of the KSU. It can be placed on a wall 
shelf or it can be wall mounted. 
To wall mount the BBU: 
- The BBU is designed to be mounted on 
a backboard, either the backboard the 
KSU is mounted on or one specifically 
for the BBU. 
. Mark for screw placement, either by 
measuring (the 2 top keyhole mounting 
slots are 8 3/4” on center) or by placing 
the BBU against the backboard (before 
installing batteries) & marking the loca- 
tion of the 2 top slots. 
- Partially insert 2 No. 12 panhead sheet 
metal screws into the backboard. 
- Suspend the BBU on these.2 screws. 
The large section of the keyhole will 
allow the unit to easily pass over the 
screwhead. 
- Slowly lower the BBU so the small sec- 
tion of the keyhole is directly behind the 
screwhead. - Tighten each screw so the unit fits 
snugly against the backboard. Insert 
2 more screws into the bottom of the 
BBU where 2 more keyhole mount- 
ing slots are located. 
IV. GROUNDING 
To ensure that the BBU will operate properly, a 
good earth ground Is recommended. 
A metallic 
COLD water pipe will usually provide a reliable 
ground path. 
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 be- 
tween the ground source and the KSU. 
THE GROUND WIRE SHOULD BE KEPT AS 
SHORT AS POSSIBLE AND SHOULD BE CON- 
NECTEDTOTHE GROUND LUG LOCATED ON 
THE BOTTOM OF THE KSU. 
V. CONNECTIONS
