Toshiba Strata S Electronic Key Telephone System Installation And Maintenance Manual

10.21 An optional handset hanger kit (HWMA) 
is also required to convert the optional EKTs for 
wall mounting. 
10.22 All optional EKTs are mounted in the 
same manner, and they may be mounted on a wall 
or any other flat, vertical surface to which the base 
can be secured. When selecting the mounting 
site, consider the EKT weight and the additional 
stresses to which the mounting will be subjected. 
10.23 Mounting screws or mollies, appropriate 
for the surface on which the telephone is to be 
secured, must be provided by the installer. 
10.24 Locking tabs secure the EKT’s base. The 
direction in which the base is attached to the EKT 
determines whether it will be used as a desk unit 
or wall unit (it is factory-configured as a desk unit). 
Disengage the locking tabs by pushing downward 
on the base (Figure 24).

10.26 Secure the base to the desired wall site. 
Use a spirit level and make certain the top of the 
base is level and that the deeper portion is down. 
10.27 Route the tail cord through the holes in 
the base and secure the EKT (Figure 26).

10.30 Installing the Handset Hanger Kit 
10.31 
Refer to Figure 27, the optional handset 
hanger kit (available from your Toshiba supplier) 
must be used whenever an EKT is wall-mounted. 
(When ordering specify if “S” EKT or optional 
EKT-the HWMA is included in the SKWM kit.) 
The remainder of the installation is the same for all 
EKT types. 
10.32 Remove the -card cover by inserting a 
paper clip in the hole at one end. Bend the cover up 
and remove it and the number card.

10.35 An optional 13-ft. handset cord is avail- 
able from your Toshiba supplier, and it is sug- 
gested that this cord be used when wall-mounting 
an EKT. 
10.40 EKT Connections 
10.41 Connect the appropriate length line cord 
to the modular connector, route the cord to the 
EKT and connect to the EKT modular jack. Test the 
EKT per Paragraph 12. 
11 SYSTEM POWER-UP INITIALIZE 
11 .Ol The Strcsta S has a list of standard 
system data assignments stored in ROM that can 
be entered at any time by performing the initialize 
sequence outlined below. The system must be 
initialized when it is first installed. This will allow 
the system to be tested and any faults to be cor- 
rected before time is spent on programming. 
11.02 To initialize the system data memory, 
refer to Figure 28 and perform the following steps: 
a) Place the power switch on the MKSU in the 
ON position. 
b) Depress the SET switch and allow it to lock

13.01 All connections to the miscellaneous 
equipment are made via the right side panel of the 
MKSU. as shown in Fiaure 29. 
13.21 Strata Sprovides access to an exter- 
nal paging system by dialing 8. The single output 
connection is made via the 8/6DO terminals on 
the MKSU right side panel, and can be used in one 
of two ways: 
a) Mount the optional 3-watt amplifier (AEPU 
PCB) and connect the customer-provided 
speaker cabling directly to the B/600 termi- 
nals (see Paragraph 13.30). 
-15 
b) If more than 3 watts are required, an external 
customer-provided amplifier can be connected 
to operate the external speaker (see Paragraph 
13.40).

13.11 A customer-provided MOH program 
source (tape deck, tuner, or commercial source) or 
the optional AMOU PCB may be used as the 
music-on-hold source. 
a) When the AMOU PCB is used, refer to Para- 
graph 07.1 Ofor installation instructions. Verify 
that the SW3 switch on the MMAU is set to 
MOU (Figure 30). Adjust the volume with the 
volume control labeled MOH on the MKSU 
riaht side oanel.

b) When a customer-provided source is used, 
connect the MOH source to the MOH termi- 
nals on the MKSU right side panel. The input 
impedance is 6ODR. Verify that the SW3 
switch on the MMAU is set to MOH (Figure

The power failure transfer feature is 
designed, upon power failure, to switch the sys- 
tem CO lines directly to dedicated- customer- 
provided conventional telephones. 
13.52 The MKSU must be equipped 
with the 
APFU PC6 and the power failure telephones must 
be directly compatible with the CO lines. 
13.53 A simplified diagram of the power failure 
transfer feature is shown in Figure 33. 
13.54 The power failure telephones are con- 
nected to the system via the jack labeled OPL on 
the right side panel of the MKSU. The OPL jack 
will accept either an 8-pin or 6-pin modular plug 
(pins 1 & 8 are not used).

13.40 External Amplifier Connection 
13.41 If more power is required than the AEPU 
amplifier can deliver, a customer-provided exter- 
nal amplifier may be connected to the 81600 ter- 
minals on the MKSU (the AEPU is not required if 
an external amplifier is used). The external speak- 
er(s) should then be connected to the external 
amplifier. 
13.42 The 600R output impedance must be 
selected with the SW2 switch on the MMAU (Fig- 
ure 31). 
13.43 The volume level through the system is

01 .OO Description 
01 .Ol The MPSA-512 power supply is perman- 
ently configured for wall mounting. Its design will 
not allow proper cooling if it is not mounted 
upright as shown in Figure 1. 
FIGURE l-MPSA-512 
01.02 Unpack and inspect the power supply and 
the enclosed hardware. Examine the package and 
make careful note of any visible damage. If any 
damage is found, bring it to the attention of the 
delivery carrier and make the proper claims. 
01.03 Check the hardware list; if it is deter- 
mined that any equipment within the carton is 
missing, contact your Toshiba supplier immed- 
iately. 
01.04 The following hardware, which is re- 
quired to connect the MPSA to the system, is 
supplied with each unit.
