							” & 2502 EB-6-l installation 
The 
EB-6 -1 is a modular electronic busy lamp 
field. Each unit is provided with a 9V DC 03A power 
supply for LED illumination. The power supply is to be 
plugged into a standard 117V AC outlet. Each BLF requires 
1 -pair cabling to the main distribution frame (MDF). 
The maximum cable length is 700 ft. using standard 24 
AWG cable and 1,150 ft. using standard 22 AWG cable. 
Refer to Section 140, “Cabling Requirements”, of this 
manual. For BLF connection, see Figures 250-3, 2504 
and 250-S and Table 240-3.

							250.3 DP-6-1 Installation 
The 
DP-6-1 is a Door/Monitor phone unit. Each 
door phone requires 1 pair cabling to the Main Distribution 
Frame (MDF). The maximum cable length is 700 ft. using 
standard 24 AWG cable and 1,150 ft. using standard 22 
AWG cable. Refer to Section 140, “Cabling Requirements” 
of this manual. 
To prepare the door phone for wall mounting losen the set 
screw and remove the door phone unit from the mounting 
plate. Use the two screws provided or other appropriate 
fastners to fiiy connect to wall surface. For door phone 
cable connection, see Figure 2506 and Table 240-3. Refer 
to Section 340, ‘Programming Sheets” for Door Phone 
assignment.

260.1 
installing Options 
Music On Hold 
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 
MDF . 
260.2 External Paging Speaker 
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 de- 
crease 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 informa- 
tion to MDF. 
260.3 External Background Music when PBS-S KTU 
is 
Used 
When a PBS-S KTU is installed, an external locally- 
provided music source can be used to supply background 
music over the External Paging System. The recommended 
output of the music source is l-watt with 600 ohms im- 
pedance. When external paging is accessed music is cut off 
from the paging speaker. Connection is made on the Jl 
block of the MDF. See Figure 260-3 and Table 240-3 for 
connection information to MDF. 
260.4 External Tone Ringer 
Provision has been made to allow connection of 
locally provided External Tone Ringer to supply common 
audible on all incoming CO/PBX calls. For this purpose a 
relay contact is prepared on the CLK-S KTlJ. which 
provides an interrupted closure (1 SEC. on/ 1 SEC. off) 
during the CO/PBX Ring Cycle. The signal of the tone 
ringer can be controlled by a locally provided control 
switch. See Figure 260-3 and Table 240-3 for connection 
information to MDF. 
2605 External Paging Amplifier 
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 locally- 
provided 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. 
260.6 
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” posi- 
tion 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 connec- 
tion information to the MDF.

260-7 Power Failure Telephones 
ET-6-l Ke:J Telephone Sets cannot be used to 
originate or answer calls during a commercial power 
failure. Locally-provided single line telephone sets can be 
installed for this purpose. The KSU provides automatic 
power failure for CO/PBX lines 
1 and 2. No optional KTU 
is required. Connection of the Single Line Telephones is 
made at the Jl block of the MDF. Single Line Telephones 
with appropriate dials (rotary or DTMF) should be installed 
if the capability of dialing out during a power outage is 
desired. See Figtire 260-3 and Table 240-3 for connection 
information to MDF.

							26043 Security Control Equipment 
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.

Fig. 260-2 PBS-S Security Control Switches 260.9 External Amplifier Control 
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.

							SECTION 300 PROGRAMMING 
310 Explanation of Programming 
1. The Electra-616 Electronic Key Telephone System 
comes nrovided with a Resident System Program in PROM 
I 
2. Keyset 1 must be installed to allow System Prograrnm- 
ing. NO other station can program system data. The 
programming procedure includes the foilowing steps: 
(Programmable Read Only Memory). When the system is 
powered this Resident System Program is duplicated in 
RAM (Random Access Memory) and becomes the Network 
Plan Memory (NPM). The NPM is the program the system 
actually utilizes. This NPM will norrna.lly be supplemented 
by progr arnrning performed at each installation to provide 
the system program desired for the individual site. The 
additional programming is entered into RAM which is vola- 
tile, but which has been provided a battery to retain 
program during power outage.

Selecting addresses via the dial pad. 
Entering data via CO/PBX button ! -6, MIC but-

Displaying data, clearing data, changing address 
(plus or minus 1 address increment) and writing 
datausing the Add-On, Last NBR, Hold and Speed 
Dial buttons. 
Repeat steps 4 th_ru 7 until all desired data has been 
written into memory. 
Return keyset 1 to “on-line” mode. 
Put the program into the working Network Plan 
Memory. This function will occur automatically 
when the entire system is idle. An alternate 
method is to depress the reset button on the 
CPU-S KTU; this will interrupt service. Testing 
of the new program can then be performed.
