Miscellaneous (MISC) PCB 
5.12 One MISC PCB must be installed in the system. 
Refer to 
Figure 3-16 on the next 
page. 
(1) Set these three switches as follows: 
SW0 - For External Music-On-Hold, set to EXT. 
For Inter- 
nal Music, 
set to MSC. 
SW1 
- If Internal Music was selected, choose a tune. 
For 
Home on the Range, select MSC-A. 
%or Green- 
sleeves,  
select MSC-B. 
SW2 - 
Select High (HI) or Low (LO) ring tone for the key- 
sets. 
(2) With th 
e system power off, 
install the MISC PCB in the 
slot labeled 
MISC with components facing left. 
(3) Turn the power on. 
Obtain a reading of 5.0VDC +O.lV on 
the cardfile as described for the CPU PCB. 
Ensure tol- 
erance. 
t 
(4) Turn off th 
e power to the KSU. 
(5) When all paging equipment has been connected and powered 
UP, adjust the volume of the external page pre-amp cir- 
cuit. 
Rotate potentiometer VRO in a clockwise direction 
to increase the volume or counterclockwise to decrease 
it. 
Door-Hate (DOOR) PCB 
5.13 The DOOR PCB is used if Door-Mates are included in the sys- 
tem. It has circuitry for up to two Door-Mate units. 
Refer to 
Figure 3-17 on page 3-33. 
(1) With the system power off, 
install the DOOR PCB in the 
slot labeled 
DOOR with components facing left. 
(2) Turn the power on. 
Qbtain a reading of 5.0VDC +O.lV on 
the cardfile as described for the CPU PCB. 
Ensure tol- 
erance. 
(3) Turn off the power to the KSU. 
(4) When the entire system has been connected and powered up, 
adjust the volume of the Door-Mate talkback and paging. 
Rotate potentiometer VRO in a counterclockwise direction 
to increase the volume or clockwise to decrease it.

D. COMPLETE THE KSU INSTALLATION 
5.14 The last steps to installing the KSU are: wall mount it, 
connect interface cables, 
and replace the cover. 
Inter-Tel 
recommendeds that the KSU be wall mounted, as opposed to attach- 
ing it to a shelf. For proper ventilation, do not put it in a 
corner. 
(1) To wall mount the KSU, 
make certain the wall can support 
twice the weight (approximately 60 pounds). 
Attach it 
with four screws through the holes at each corner. 
(2) Connect the four interface cables from the MDF. Refer to 
Figure 3-18 on the next page and follow these 
steps: 
a. Feed each cable through the bottom access cutout on 
the left of the KSU (below the MDF PCB). 
b. Then feed them under the protruding bracket. 
C. Attach each female connector to the corresponding 
male connector. 
d. 
Secure the cables with tie wraps around the cables 
and bracket. 
i 
(3) After programming the data base, attach the cover and 
secure it at each corner with the four screws provided.

6. KEYSET INSTALLATION / 
6.01 The system may be configured with 24 keysetsand eight of 
them may be Power Failure Transfer (PFT) units. 
Keysets are 
installed in the following manner. 
Photographs 
of the keyset 
bottoms and control boards are shown in Figures 3-22 to 3-25 on 
pages 3-40 to 3-43. 
(1) Unpack the keysets, check for damage, and make sure all 
modular parts are included. 
The modular parts include 
the keyset, 
one seven-foot two-pair power cord, one stan- 
dard two-pair handset cord, and one handset. 
The Hitec 
models will include one brass strap and screw for stress 
relief when the power cord is plugged into the bottom of 
the keyset. 
If there is damage or if parts are missing, 
contact Inter-Tels Order Processing Department. 
(2) Turn on power to the KSU. 
(3) Without th e keyset connected, 
check that the +27VDC from 
the KSU is on the BLACK terminal in the jack. 
Ground is 
on the YELLOW terminal. 
If -27VDC is measured, check the 
cabling for a reverse pair. 
Incorrect voltage polarity 
will result in a blown fuse when the keyset is connected. 
(4) Mount the jack on the wall. 
r 
(5) Set the intercom number dial setting using the switch on 
the bottom of the keyset. 
These numbers are assigned by 
subtracting  one  
from the second digit of the circuit 
number.
