10 MISCELLANEOUS 
EQUIPMENT CONNECTIONS 
10.00 Wiring Connections 
10.01 All connections to miscellaneous 
equipment, except Amplified Conference (see 
Paragraph 10.90), are made via the terminal 
strip mounted on the HINU PCB (TBl as shown 
in Figure 36). 
10.10 MOH/BGM Source 
10.11 Music-on- Hold requires either the 
SMOU PCB, which generates electronic melo- 
dies, or a customer-provided external music 
source, such as an FM radio. If the SMOU is 
used, it must be mounted on the HINU PCB at 
Pl connector and the SW1 switch on the 
HINU must be set to “MOU” (as shown in Fig- 
ure 36). 
10.12 If an external music source is used for 
Music-on-Hold, its output leads must be con- 
nected to the MOH terminals on the HINU PCB 
and SW1 must be 
set to “MOH”. 
10.13 Adjust the MOH volume with the 
600R 
MOH SW1 
I . HINU 
SMOU 
FIGURE 36 - HINU PCB 
MOH volume control on the HINU. Maximum 
volume is limited by internal circuits in order 
to comply with FCC regulations. See Para- 
graph 10.70 for the correct volume 
setting 
sequence. 
10.14 Background music is provided via the 
same source as music-on-hold. 
Either the 
-26-  
						

							SMQU or an external source may be used (see 
Paragraph 10.10). 
10.20 External Paging Connections 
10.21 
Strata provides access to an exter- 
nal paging speaker. This speaker ,can also be 
used for background music if programmed. 
The connection is made via the EXP or 600 
terminals on the HINU, and can be used in one 
of three ways: 
a) To operate a customer-provided speaker di- 
rectly via an internal 3-watt amplifier located 
on the HINU PCB (EXP terminal). 
b) If more than 3 watts are required, an exter- 
nal customer-provided amplifier can be con- 
nected to operate the external speaker (600 
terminal). 
c) If talkback capability is required, a custom- 
er-provided talkback amplifier/speaker can be 
connected (600 terminal). 
10.30 Direct External Speaker Connection 
10.31 The exact number of speakers that 
may be connected to the 8-ohm, 3-watt output 
is dependent on the type of speaker used, con- 
ductor resistance, and desired volume. 
10.32 The 8-ohm output impedance must be 
selected with the SW1 switch on the HINU 
(Figure 36). The switch must be on the side 
labeled 8 R whenever the EXP terminal is 
used. 
10.33 Connect the external speaker to the 
EXP terminal on the HINU. 
10.34 Adjust the speaker volume with the 
EXP volume control on the HINU according to 
Paragraph 10.70. 
10.40 External Amplifier Connection 
10.41 If more than 3 watts of power is re- 
quired, a customer-provided external amplifier 
may be connected to the 600 terminal on the 
HINU (connect external speakers to the exter- 
nal amplifier). 
10.42 The 600-ohm output impedance must 
be selected with the SW1 switch on the HINU 
(Figure 36). The switch must be on the side 
labeled 600 R whenever the 600 terminal is 
used. INSTALLATION INSTRUCTiONS 
SECTION 3QO-020-200 
JULY 1988 
10.43 The level is fixed and input must be 
controlled by the external amplifier. The HINU 
amplifier is not used for the 600-ohm mode. 
See Paragraph 10.70 for the correct volume 
setting sequence. 
10.50 Talkback Amplifier 
10.51 A customer-provided talkback ampii- 
fier/speaker may be connected to the 600 ter- 
minal on the HINU. 
10.52 For talkback operation, use the same 
procedure as External Amplifier Connection, 
Paragraph 10.40. 
10.60 Background Music 
10.61 Background music (BGM) can be pro- 
vided in two ways through the 
Strata sys- 
tem: 
a) Internal to the system using the MOH 
source (SMOU or external music source). 
b) External to the system when an external 
amplifier is used on the External Page feature. 
10.62 Internal BGM uses the music-on-hold 
program source that is selected by SW1 
(“MOH” or “MOU”) on the HINU. It is broad- 
cast through all EKT speakers (under the indi- 
vidual control of each station user) and can be 
heard if the m key is operated with the 
handset on-hook and no line selected. 
10.63 As a programmable option, BGM from 
the MOH source can be heard via the external 
speaker (see Section 300-020-300, Program- 
ming Procedures). 
10.64 BGM is automatically pre-empted 
when a page or ringing signal must be output 
from an EKT speaker or the external paging 
connections. 
10.65 Overall system BGM volume is set 
with the BGM volume control on the HINU 
(see Paragraph 10.70 for the correct volume 
setting sequence). The volume at individual 
stations is set with volume control on the 
right-hand side of the EKTs. 
10.66 If BGM is connected via an external 
amplifier on the external page, it can be heard 
from the external speaker only. Strata, if 
required, can provide a dry contact control sig- 
nal for muting the external BGM when a page 
-27-  
						

							INSTALLATION INSTRUCTIONS 
SECTION 300-020-200 
JULY 1986 
is in progress. 
10.67 To provide external BGM control, con- 
nect the BR terminals on the HINU to the con- 
trol terminals (mute, mike switch, etc.) on the 
amplifier (see Figure 37). 
FIGURE 37 
EXTERNAL AMPLIFIER HOOK-UP 
10.70 Volume Setting Sequence 
10.71 Refer to Figure 36 and adjust the vol- 
ume for MOH, BGM and External Page in the 
sequence outlined in Paragraph 10.72. 
10.72 Adjust the MOH level first using the 
following procedures: 
1) Set the MOH volume control to its lowest 
level (counterclockwise). 
2) Lift the handset on one station and call 
another station using two CO/PBX lines. 
3) At the called station, put the incoming call 
on hold, and listen on the handset (not the 
speaker) of the calling EKT. 
4) Using the volume control on the MOH 
source, adjust MOH to the most comfortable 
level without distortion. 
5) If a higher level is needed than can be pro- 
vided by the MOH source, turn the MOH vol- 
ume control slowly clockwise to achieve the 
most comfortable level without distortion. 
6) Release the connection between the two 
CO lines. 
7) No further changes should be made using 
the MOH control or the MOH source volume control. 
10.73 If an external speaker is to be used in 
the system, adjust the external page and BGM 
levels as follows: 
1) Adjustments should be made while an 
actual external page test is in progress. Adjust 
the voice volume to a comfortable level. The 
procedure varies depending on the paging sys- 
tem configuration and the setting of the 
8/600-ohm switch (SWl): 
a) 8 ohms with no external amplifier - 
adjust output level using the EXP volume 
control on the HINU. 
b) 8 ohms with external amplifier - adjust 
output level using the EXP volume control 
along with the controls on the external 
amplifier. 
c) 600 ohms - the volume level through 
§trata is fixed in this mode; adjust- 
ments must be made using the external 
amplifier controls. 
2) If background music is to be heard over the 
external speaker: 
a) Adjust voice page level per above proce- 
dure. 
b) With music playing over the speaker, 
adjust the volume to a comfortable level 
using only the BGM control on the HINU. 
Do not tamper with the EXP control, exter- 
nal amplifier adjustments or MOH adjust- 
ments. 
c) If background music is connected 
directly to the external amplifier instead of 
through the system, all adjustments must 
be made on the external amplifier. 
10.74 If no external speaker is to be used in 
the system, adjust the BGM level as follows: 
1) Using an EKT in speakerphone mode, make 
a call on a CO line, and adjust the EKT speaker 
volume to a comfortable level. 
NOTE: 
This should be done in an area that has 
background noise that is about average 
for that particular installation. 
2) Using the m key, disconnect the CO call 
and activate BGM at the EKT. 
3) Using only the BGM volume control, adjust 
the BGM to a comfortable level. Do not use the 
EKT volume control.

10.80 Night Relay Service 
10.81 As an option, 
Strata can provide a 
dry contact for the purpose of controlling an 
external loud ringing bell (or similar device) or 
an answering machine when the system is in 
the “NITE” mode. 
10.82 To provide this service, connect the 
external device to the NR contacts on the 
HINU (refer to Figure 36). 
IMPORTANT! 
The NR and BR relay contacts are rated 
at 24 VDC/l amp and are not intended 
to operate high power devices directly. 
If the power required for the device 
being controlled exceeds the contact 
ratings, an external slave relay must be 
used. 
10.83 The W3 (refer to Figure 36) strap 
option on the HINU allows the NR relay to 
function in one of two modes: 
a) Answering Machine Control - if the W3 
strap remains intact, the relay is operated con- 
tinuously when the system is in night service. 
This mode is intended for indirect control of an 
answering machine. 
b) Night Bell Control - if the W3 strap is cut, 
the relay pulses at a 1 -second on, 3-second off 
rate when the system is in night service and 
an incoming call is ringing the system. This 
mode is intended to be used for indirect con- 
trol of an external night bell. 10.90 Amplified Conference 
10.91 A single Amplified Conference feature 
may be installed in the system, which requires 
a customer-supplied two-way amplifier. The 
Lorain VFR 5050 (R-TEC Systems) is known to 
be compatible. 
10.92 Refer to the amplifier’s installation 
procedures from the manufacturer and con- 
nect the amplifier between the voice leads (T 
and R) of stations 18 and 19. Ensure that 
these stations have been programmed for 
amplified conference (Program 02). 
10.93 The amplifier is automatically con- 
nected once the conference is established. 
Amplification exists between any two outside 
CO lines used as well as between the second 
CO line selected and the station (no amplifica- 
tion between the first CO line and the station). 
If Trunk-to-Trunk connections are allowed in 
the system (Program 02), the CO line-to-CO 
line connection will be amplified. There is one 
Amplified Conference available that is estab- 
lished on a first-come/first-served basis only.
