The following conditions should be met at the site
against accident or flooding. Where possible
use
of a
wooden backboard is recommended for this purpose.
due to the possibility of leaks or condensation causing
damage.
120.2 Grounding Requirements
The
KSU must be well-grounded. If a good conduit
ground is not present at the dedicated AC outlet, the
following steps should be taken:
1. Provide a suitable waterpipe ground in accordance with
the local operating (telephone) company procedures.
2. If no waterpipe is available, a ground rod should be
installed in accordance with local operating company
procedures.
3. In the case where a ground other than conduit ground
is used a grounding terminal is provided on the ES-6 -1
as shown below in Figure 120- 1.

Other Consideratiaons
130.1 Electrical Noise Generators
Certain
equipment, such as welding machines,
thyrister-driven power supplies, large electrical motors, etc.
generate electrical noise. As a stored program machine the
Electra-616 System is vulnerable to this noise. When this
type of machine is present at an instahation, the following
precautionary steps are urged:
Locate KSU, telephone sets, and cabling away from
1.
these machines.
2. If cables must pass near these machines, use shielded
cabIe with the shield grounded.
3. Ensure all machines of this type are well-grounded to a
separate ground to minimize noise interference.
130.2
Pre-installation Site Survey
Since a pre-installation survey is generally required
to plan for application and installation, a check of the
matters covered so far in this section at this time will pre-
vent later problems.
130.3 Additional Equipment
In addition to electronic station equipment and
the KSU and their contents, other equipment is required.
This includes cables, modular connecting jacks, quickconnect blocks (or smimlar apparatus), etc. This additional
equipment must be locally supplied.

should be programmed as “not installed” when programming for CO/PBX line assignment. See Section
300 “Programming”
of this manual for instructions
on programming CO/PBX line assignment. This will
avoid confusion when attempts to access unconnected
CO/PBX lines are made. The DSI-S or MFI-S in the
first designated KTU position (DCI/MFI 1) serve CO/
PBX lines 1 through 3. A DCI-S or MFI-S in the
second designated KTU position (DCI/MFI 2) serve
CO/PBX lines 4 through 6. Refer to figure 230-2 for

For a description of the Resident System Program see
Section 300 “Programming”. When the CPU-S KTU
is removed for long-term storage, set the SW1 switch
to the OFF position. This will prevent the battery from

When Door Phone 1 is required as a Door Phone, set
the SW1 to the “D” position on the DPH-S KTU.
(In the case of Door Phone 2, set the SW3 to the
“D” position.)
When Door Phone 1 is required as a Monitor Phone,
set the SW1 to the “M” position on the DPH-S KTU.
(In the case of Door Phone 2, set the SW3 to the “M”
position.) and remove the straps Sl and S2 on the
DPH-S KTU. (In the case of Door Phone 2, remove
the straps S3 and S4). Then the voice from Key Set
will be cut off when Door Phone is accessed, and the
voice from DP-6-l is more amplified compared with
being used as Door Phone.

3. AHR-S KTU
Located on each DCI-S and MFI-S KTUs are three
straps (one for each line circuit) that should be
removed when AHR-S KTU is installed for Automatic Hold Release option. When AHR-S KTU is not
installed, the straps should be left connected to the
solder terminals. Refer to Figure 230-3 for terminal
designations. The AHR-S will release a CO/PBX line
which is on hold when the outside party abandons the
call. A timed disconnect signal of more than 150 milliseconds must be provided from the CO or PBX to
enable this option (the AIIR-S does not recognize a
reversal of polarity). The AHR-S KTU serves up to
6 CO/PBX lines and is installed in ES-6-l KSU.
Remove the straps when AHR-S KTrJ is installed.

Provision has been made to allow connection of a
locally provided external music source to provide Music-
On-Hold for held CO/PBX calls. Connection of the Music
Source is made at the Jl Block of the Main Distribution
Frame (MDF). The output signal level should be approxi-
mately 1 milliwatt with 8 ohms impedance. See Figure
260.3 and Table 240.3 for connection information to

External Paging Speaker
MDF .
When a PBS-S KTU is installed in the ES -6 - 1 KSU,
external paging with meet-me answer can be provided. The
PBS-S KTU contains a 1 -watt Amplifier and Control
Circuit for one-zone paging (when a l-watt amplifier is
insufficient, see Section 260.5.) The External Speaker
should be locally-supplied in correspondence to the output
impedance of 600 ohms. The Volume Control (VRl),
located on the PBS-S, provides a way to increase or decrease the output signal of the amplifier to the speakers.
To adjust output signal, turn VR1 clockwise to increase
signal, and counterclockwise to lower signal. An LED is
provided on PBS-S KTU to indicate when paging is being
used. When an External Page is answered (meet-me-answer),
the PBS-S is released to allow access for another page.
See Figure 2 60-3 and Table 240-3 for connection information to MDF.
The PBS-S
KTU contains a l-watt Amplifier and
control circuit for external paging. For applications where
1 -watt is insufficient, an external amplifier may be used.
Provision has been made to allow connection of a locallyprovided amplifier to the MDF for this purpose. The PBS-S
KTU is required when an external amplifier is used. See
Figure 2604 and Table 240-3 for connection information
to the MDF.

External Background Music when External
Amplifier is Used
To provide for background music with an external
amplifier installed, set the SW4 switch
io
the “ON” position and the SW3 switch to the “OFF” position on the
PBS-S KTU. When background music is not required set
the SW3 switch to the “ON” position and the SW4 switch
to the “OFF” position. Music will be cut off from the
paging speakers when external paging is accessed. The
output level and impedance of the music source should
match the input level and impedance of the external
amplifier. See Figure 2604 and Table 240-3 for connection information to the MDF.

26043 Security Control Equipment
260.9 External Amplifier Control
Provision has been made to allow connection of a
locally-provided security control system. For this purpose
the PBS-S KTU contains 2 individual control circuits that,
when activiated, provide an audible alarm through all idle
keyset speakers and a visual alarm on each keyset display.
Each security circuit can be activiated by means of an
external make (closed) or break (open) contact. The SW1
switch on the PBS-S KTU is used to set the desired break
or make detection for security circuit one and the SW2
switch performs the same function for security circuit two.
For connection information to the MDF see Figure 260-3
and 260.4 and Table 240-3.

A set of dry contacts is provided on the PBS-S
KTU, which can be used to control an auxiliary relay for
External Paging. Although this option is not required when
an external amplifier is used, it may be desired in some
applications. When an external page is activiated the EAS
and EAM contacts are closed for the duration of the page.
In the idle condition the closure is made between the EAS
and EAB contacts. See Figure 2604 and Table 240-3 for
connection information to the MDF.
