SU-114N version 1.3 R&D Department 5

Amplifier, speakers line

and critical path surveillance unit

SU-114N

1. INTRODUCTION

The unit is modular in design, with the capacity

for surveillance of 14 zones.

It performs three surveillance functions:

Surveillance of the loudspeaker line

impedance

Surveillance of the power unit status of the

Optimus 6 series

Critical path surveillance.

These functions allows to comply with the

EN60849 standard.

Loudspeaker line surveillance: The SU-114N

injects various frequencies into the loudspeaker

line, which it then collects and analyses in order

to detect the status of the line (open line, short

circuit or correct line status).

The frequencies used for this monitoring can be

no audible (20 kHz or 18 kHz) or audible (4 kHz

or 400 Hz).

Constant monitoring (continuous measurement)

is achieved through the use of no audible

frequencies.

Audible frequencies are generally used to confirm

the line faults detected during measurement at

high frequencies.

Surveillance of the power unit status: The

SU-114N detects the 24 V DC received from the

power units through the SURVEILLANCE

connection of the amplifier.

Critical path surveillance: In installations with

an evacuation PA system, this consists in

continuous surveillance of the entire path of the

evacuation signal, from its origin (the capsule of

the MD-500EM desk) to the loudspeaker that

plays the message.

Main characteristics:

Allows the surveillance of Optimus amplifiers

with surveillance connector (UP-66, UP-67,

UP-126, UP-127, UP-246, UP-247, UP-366,

UP-367, UP-67M4, UP-127M4, UP-247M2 and

UP-487).

Triple frontal status indicator for each zone.

Surveillance capacity of 14 zones.

Input contact (MEASURE ACTIVATION), which

allows an external device to activate

measurement at audible frequencies (4 kHz or

400 Hz).

Open collector output contact (MEASURE

INDICATION). This is activated when the SU-

114N is performing surveillance.

Allows the surveillance of lines in installations

with volume attenuators.

Allows the surveillance of lines in installations

with music programs.

PC configuration via Ethernet.

Setting from PC or front keypad.

Double Ethernet connection for installations

with redundant network systems.

Surveillance of unit operation by means of the

PA Manager (SMP-250V2) software or through

the Web browser.

IP address configuration by means of a

Dipswitch and by software, facilitating the

replacement of equipment in an installation.

In installations with backup amplifiers and a

COU-02/0, it interacts with this, ordering the

replacement of the faulty amplifier with the

backup amplifier when an amplifier error is

detected.

24 VDC power supply (power supply not

included).

Occupies one standard 19'' Rack unit.

the diagram

attached.

3. REAR VIEW

(1) Ethernet B connector

RJ-45 connector. It is used, in a redundant

network, as a secondary connection to the

Ethernet network. In installations with a

redundant network, if the connection to ETH A

fails, the unit automatically switches to this B

connection, so that the PA system continues to

operate.

(2) 10 Mb indicator of the Ethernet B input

Indicates the speed of the Ethernet network

connected to the Ethernet B input. If the LED is

lit, it indicates a speed of 10 Mb. If it is not lit, it

indicates a network speed of 100 Mb.

(3) ACT indicator of the Ethernet B input

When lit, it indicates that data is being sent or

received through the Ethernet B input.

(4) LINK indicator of the Ethernet B input

When lit, it indicates the connection of the

Ethernet B input with the HUB or SWITCH.

(5) Ethernet A connector

RJ-45 connector. Used for connection to the

Ethernet network.

(6) 10 Mb, ACT and LINK LED indicators of

the Ethernet A input

These serve the same purpose as the Ethernet B

indicators, applied in this case to the Ethernet A

input.

(7) CTRL OUT strip

Open collector output contact*. It is activated

when surveillance detects amplifier, loudspeaker

line or critical path errors.

(8) Power supply input

Used to power the SU-114N. Connect a power

supply of 24 VDC / 1.5 A to this input.

(9) Ground to chassis connection.

(10) Supply fuse

2 A fuse inside the unit. To gain access to it, it is

necessary to remove the cover of the SU-114.

(11) Measure activation

Input contact, which allows an external device to

activate measurement at audible frequencies (4

kHz or 400 Hz). It is activated when the contact

is connected to ground.

(12) Measure indication

Open collector output contact*. This is activated

when the SU-114N is engaged in measurement.

It is used:

In installations with attenuators, in order to

activate the security paging of the attenuators

when loudspeaker line surveillance is

performed.

In installations without attenuators and with

music programs, in order to attenuate the

high frequencies of the music when

loudspeaker line surveillance is performed,

through a contact of a UMX-ECT card

configured for this purpose.

In installations without attenuators and with

music programs, without UMX-ECT cards or

without a UMX-02/0 matrix, in order to stop

the music when loudspeaker line surveillance

is performed. For this purpose the Measure

Indication is normally used connected to an

external relay, whose function is to cut off the

music program during the measurement

process.

(13) Ground connections

These are necessary in order to reference the

MEASURE INDICATION and MEASURE

ACTIVATION contacts mentioned earlier.

(14) RS-485 ADDRESS Dipswitch

The SU-114N communicates with the control PC

and the various elements of the SMP-250 system

(SU-214/0N, UMX-02/0, MD-500, MD-500EM...)

through a RS-485 bus. For this purpose it uses

the CSMA (Carrier Sense Multiple Access)

protocol. This Dipswitch enables a communication

address to be assigned to the unit, inside the RS-

485 bus. Each unit connected to an RS-485 bus

must have a different address. Table III shows

the possible values of this Dipswitch. To

configure it, please read section 7.

(15) CSMA / POLLING switch

The SU-114N uses the CSMA protocol. Move this

Dipswitch to the CSMA position.

(16) RS-485 IN connector

RJ-45 connector. This is used to connect the SU-

114N to the RS-485 communication bus.

(17) RS-485 OUT connector

RJ-45 connector. This is used to give continuity

to the RS-485 bus. If this output is used, the RS-

485 ON/OFF switch must be moved to the ON

position.

(18) RS-485 OUT ON/OFF switch

In the ON position it activates the RS-485 output.

(19) RX and TX indicators

Their blinking indicates transmission (TX) or

reception (RX) of data through the RS-485 port.

(20) Connections for surveillance of the

amplifier / zone number 14. See section 8.1.

(21) Connections for surveillance of the

amplifier / zone number 1. See section 8.1.

4. CONFIGURATION OF THE SU-114N FAIL RELAYS

Inside the unit there are

three jumpers for each of

the zones of the SU-

114N, by means of which

the FAIL relays can be

configured.

Figure 3:

Switching on jumper (A)

connects contact 1 of the

card to ground.

Switching on jumper (B)

configures the relay as

NO (normally open),

while jumper (C)

configures the relay as

NC (normally closed).

The default setting for

the unit has jumpers A

and B switched on

(contact 1 to ground and

relay NO).

5. CONFIGURATION OF THE TIMING SELECT DIPSWITCH

It is possible to configure the interval of time between surveillance sessions by means of a TIMING

SELECT Dipswitch on the front (see Figure 1, no. 2), consisting of four switches.

The range of time has values of between 10 and 140 minutes, at intervals of 10 minutes.

There is a configuration for continuous measurement (all switches to OFF).

To disable measurement, move the four switches to ON. In this case, the SU-114N will perform

measuring operations when it is scheduled to do so (see section 9.3) or when the Measure Activation

contact is activated.

Whatever the configuration of the TIMING SELECT Dipswitch may be, whenever the SU-114N is turned

on, loudspeaker line impedance and critical path surveillance is automatically performed.

The configuration of these switches affects all the surveillance outputs of the SU-114N, except the output

that has been defined by software as the backup amplifier zone and which therefore performs continuous

measurement.

In SU-114N installations with MASTER/SLAVE topologies, all the SU-114N units will follow the

configuration of the TIMING SELECT Dipswitch of the MASTER.

When the TIMING SELECT Dipswitch configuration forces measurement, the SU-114N performs

surveillance of the loudspeaker line by means of the No Audible frequency, and then surveillance of the

critical path on the cards that are configured for this purpose.

6. CONFIGURATION OF THE UNIT IP ADDRESS

The dipswitches that enable the IP address of the SU-114N to be manually configured are situated on the

lower part of the unit, protected by the cover. This address identifies the unit in the network and

therefore each unit must have a different IP address.

An IP address is represented by means of a 32-bit binary number. The IP addresses are expressed as

decimal-notation numbers: the 32 bits of the address are divided into four octets (an octet is a group of 8

bits). Each octet is represented by A0 to A7 for the first octet, B0 to B7 for the second octet, C0 to C7 for

the third octet and D0 to D7 for the fourth octet.

Each bit can have the value 0 (dipswitch OFF) or 1 (dipswitch ON). In order to obtain the decimal value of

the octet, the decimal values of each bit that is in the ON position must be added up (from the top down:

1, 2, 4, 8, 16, 32, 64 and 128).

When the IP address of a unit is changed, it is necessary to restart the unit by means of the ON/OFF

switch on the front.

Figure 4 shows an example in which the IP address 192.168.100.128 is configured.

Table II on the next page shows all the Dipswitch combinations from 0 to 255.
