7. DOOR-MATE INSTALLATION 
7.01 The system may support two Door-Mate units. The one-pair 
cable should already have been run to the Door-Mate locations and 
terminated on the MDF (as instructed earlier in Sections 3A and 
4c). Refer to Figures 3-26 and 3-27 on the following pages and 
install them as follows: 
(1) Unpack and inspect each Door-Mate for damage. If damage 
is found or parts are missing, contact Inter-Tels order 
Processing Department. 
(2) On the front of the Door-Mate, remove the single screw 
and separate it from the Wall-Mount Bracket. 
(3) Attach th e Wall-Mount Bracket to the wall, placing it 
over the cable. Secure it with the two screws provided. 
(4) Connect the cable to the Door-Mate. 
Either wire may be 
attached to either screw terminal. 
(5) Place the Door-Mate back into the bracket and secure with 
the one screw originally removed.

8. BATTERY BACK-UP INSTALLATION i  
8.01 There are two battery 
styles available for use with the 
system. Depending on the physical size chosen, they are either 
installed inside the KSU with the provided mounting brackets or 
are installed outside the KSU. 
Refer to SYSTEM SPECIFICATIONS 
for information about selecting batteries for system back-up. 
The type and size are critical. 
(1) Connect the batteries in series to obtain 24V and make 
sure they are connected in correct polarity. 
They must 
be of the same ampere/hour rating and also have the same 
charge/discharge level. 
They must be lead calcium grid 
batteries and charge at a rate of 2.27V per cell. 
(2) On the front of the power supply, set the battery EXTER- 
NAL/INTERNAL switch. 
This is dependent on the size of 
batteries used. 
a. 
If you are 
installing small batteries on 
the inside 
of the KSU, put the switch in the INTERNAL 
position. 
b. If you are installing full-size batteries 
outside of 
the KSU, put the switch in the EXTERNAL position. 
(3) Turn off AC power to the KSU. 
(4) Refer to Figure 3-7 on page 3-17. Then connect the bat- 
teries to the power supply as follows: 
a. The internal batteries connect to the RED (+) and 
BLACK (-) wires exiting from the lower right front of 
the power supply. 
A jumper wire is provided to con- 
nect the internal batteries. 
b. The external batteries connect to the EXT BATT screw 
terminals on the right edge of the power supply. 
(5) Turn on the AC power. 
(6) Wait approximately six hours for the battery pack to par- 
tially charge. 
NOTE: Since charging time depends on the amp/hour rat- 
ing, this may vary. 
The system charges at a low rate to 
protect against battery damage.

(7) After an adequate time to partially charge, pull the AC 
power plug to remove power. 
Make sure the system is 
operating. 
If not, measure voltage across the battery 
connection. 
A voltage of 20-24V must be present to run 
the system. 
If less than 2OV, replug the AC power cord 
and allow more time to charge before testing it again. 
(8) Re-apply AC power to the System. 
9. 
INSTALL THE SMDR OUTPUT DEVICE 
9.01 The output device for the Station Message Detail Recording 
(SMDR) feature must have these characteristics: 
A. It must be RS232C compatible, 
formatted for serial ASCII 
with no parity. 
B. It must communicate at 300 baud. 
C. The RS232C interface must be equipped with a male 25-pin 
subminiature 
D connector. 
Consult the owners guide for 
the device to verify that the individual pin functions 
are identical. 
If necessary, 
change the connector on the 
device to match 
functions for the the requirements for the system. 
Pin 
interface are as follows:

9.02 To connect the output device to the MDF PDB: 
(1) Before connecting the terminal cable to the MDF PCB, turn 
on the AC power to both the device and the system. 
This 
prevents electrical surges from being transmitted by the 
interface. 
(2) Carefully connect 
the RS232C interface cable from the 
device to the RS232C connector on the MDF PCB.

10. INSTALL EXTERNAL MUSIC-ON-HOLD 
10.01 There is a female connector on the MDF PCB for an external 
music source. It will accept a l/8-inch mini-phone jack which 
can be purchased at any electronic parts store. 
10.02 To install the customer-supplied external music source: 
(1) Attach th e mini-phone jack wire to the music source, 
either at the earphone jack or directly to the speaker 
output wires. 
(2) Then plug it into the connector on the 
MDF PCB. 
r 
(3) Make sure SW0 switch on the MISC PCB is in the EXT posi- 
tion. Refer to page 3-31.
