in

turn

requires

power from a grounded 115VAC

outlet.

The

outlet

should

be

separately

fused

and

rated

at

15

amps.

03.03

Two power supplies

are

available:

• MPSA-200

are

required

within

a

system.

Up

to

16 BLF

EKTs may

be

installed

with

an

EPSA-104

power

supply.

03.04

The

54-inch

cord

provided

to

connect

the

power

supply

to

MTOU

PCB OPTIONS

05.01

The

MTOU

houses

several

options

that

must be

considered

before

it

is

installed

in

the

MKSU,

they

are:

• Background Music

Relay

Service--

the

optional

BR

relay

(Kl

socket,

Figure

4), if

installed,

provides a

dry

contact

at

the

BR

terminals

on

the

front

of

the

MTOU

to

control

cut-off

of

BGM

during an

external

page.

The

relay

operates

whenever

an

external

page

occurs.

Test

Procedure

1.

Obtain

a

suitable

voltmeter

and

set

it

for

a

possible

reading

of

up

to

250VAC.

2.

Connect

the

meter

probes

between

- 6 -

the

two

main AC

voltage

points

on

the

wall

outlet.

The

reading

ob-

tained

should be

90"-'l30VAC.

3. Move

one

of

the

meter

probes

to

the

3rd

prong

terminal

(GND).

Either

the

same

reading

or

a

reading

of

0

volts

should be

ob-

tained.

4.

If

the

reading

is

OV,

leave

one

probe

on

the

GND

terminal

and

move

the

other

probe

to

the

2nd

voltage

terminal.

If

a

reading

of

OV

is

obtained

on

both

voltage

terminals,

the

outlet

is

not

pro-

perly

grounded.

Omit

Steps

5/'./

7,

and

proceed

directly

to

Step

8.

5. If a

reading

of

OV

on

one

terminal

and

a

reading

of

90

~

130VAC on

the

other

terminal

is

not

obtained,

the

outlet

is

not

properly

groun-

ded.

Omit

Steps

6

&:

7,

and

pro-

ceed

directly

to

Step

8.

6.

If

a

reading

of

OV

on

one

terminal

and

a

reading

of

90/\/130VAC

on

the

other

terminal

is

obtained,

re-

move

both

probes

from

the

outlet.

7.

Set

the

meter

on

the

noHMS/Rxir'

scale,

place

one

probe

on

the

G

ND

terminal

and

the

other

probe

on

the

terminal

which

gave

a

reading

of

OV.

A

reading

of

less

than

one

ohm should be

obtained.

If

a

reading

of

less

the

one

ohm

is

not

obtained,

the

outlet

is

not

ade-

quately

grounded.

8.

If

the

above

tests

show

that

the

outlet

is

not

properly

grounded,

that

condition

should

be

corrected

(per

Article

250

of

the

National

Electrical

Code)

by a

qualified

electrician

before

the

STRATA

VI

system

is

conn(~cted.

06.27

Ensure

that

the

power

switch

on

the

MTOU

is

OFF,

then

plug

the

power

supply

into

the

115VAC

outlet

and measure

the

voltage

at

the

MTOU

input

terminals.

Correct

any

problems

before

proceeding.
