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.

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.

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.
