2 INSTALLATION
The equipment allows the installation in wall or rack, and in vertical or horizontal
orientation. Installation accessories are available to facilitate the installation procedure.
To fix the equipment to the supports, of the 8 outside screws of the equipment shall
be removed. From each pair of screws the one that is closer to the side where the
support will be placed is removed. The clamping wings are inserted through the
corresponding perforations and the screws that fix the equipment are placed preventing it
from falling.
2.1 Orientation change
To change the orientation, the screws that fix the front of the equipment to the
chassis are removed. This way, the front is released, and the orientation can be changed
so that the controls are accessible according to their final position.
2.2 Inputs and outputs
In this chapter, the connectors of the ONE series are described.
The enclosure has 7 pre-cut holes for the entry and exit of the wiring, easily removed
with a screwdriver. Its size is 36mm, which matches the size of the racors for 32mm
tubes.
2.2.1 Power supply
The equipment has redundant power supply according to EN5 - thanks to the battery
charger accessory. The AC power supply range is universal type 90-2 0 V ~ input and
frequency 50 or 60Hz, with integrated Power Factor Correction (PFC).
The backup source consists of a battery that is installed internally with the included
battery charger by activation.
a) Main power input
The power connection is made directly
by wiring it to the interior of the equipment,
it must include the power disconnection
elements externally. To manipulate the
equipment, the external power must be
disconnected.
There is a three-pole 1.5-2.5mm cable
connector marked for Phase, Neutral and
Ground. The cable can be inserted and
removed thanks to the push button.
Illustration 3: Front fixation and interior view
Illustration 4: Power connections

b) Disconnection switches
These switches cut the power path of the power supply and the battery. They help to
avoid the danger of sparks when connecting the battery and it's useful for restart the
equipment completely.
2.2.2 Battery installation
Before installing the battery it is recommended to switch
off the equipment using the switches in the supply circuit.
This system allows to mount the battery safely and avoiding
unwanted short circuits.
The equipment has a cavity for 12V sealed lead-acid
batteries with a maximum size of 167 (height) x181 (width)
x76 (depth) mm.
The equipment consumes 9Ah of battery for 2 h in stand-
by and 8Ah for one hour in evacuation at maximum power. With the recommended
battery brand YUASA NP17-12I we have 17Ah, enough to comply with stand-by and
evacuation needs.
Additionally, a 25 Amps safety fuse is available for the battery input located on the
supply plate.
Battery assembly
Unscrew the fixing part and release the flange that holds the cable for transport.
Connect the battery, put in the housing and fix it again. Remember that lead acid
batteries should not be installed inverted.
2.2.3 Fire central interface
The emergency activation interface is indicated for interconnecting with fire control
and indication equipment. All input connections are supervised in the event of failure in
the transmission line. Said interface is composed of three sections.
5
Illustration 5: Battery installation

Connection is made using female euroblock connectors given with the equipment. The
cable section range for each pole of this connector is: 0,1 1,5mm2 (30 1 AWG).→ →
Inputs are activated when the dry contact is voltage free. (N.O.= normally open)
a) Zone emergency activation inputs
These inputs are connected the same way as the general entrance to allow link
supervision.
Default function: When the input of one the zones Z1...Z6 is activated, the state of
general emergency will get activated and the list of evacuation messages for these
zones will start to be played. The rest of zones will play the list of alert messages that
can be configured in the configuration menu.
If the contact is deactivated, the reproduction of the messages will be paused, but a
restart operation will be needed to go back to the inactivity mode or PA.
b) General emergency activation input
Supervised inputs for voltage-free dry contact connection (N.O.): Restart and
Emergency.
So that the link can be supervised, the connection of the dry contact to the equipment
must be carried out by means of two external 10K resistors (supplied with theΩ
equipment), placed at the output of the fire panel as indicated in the illustration 6.
Function: When the general emergency entrance (EMG) is activated by means of a
contact closure (0V), the equipment will automatically change from working mode to an
emergency state, and emitting the voice evacuation message through all zones of the
system. When the reset input (RST) is activated, the equipment will exit the emergency
operation mode and return to the idle state (PA).
It can be configured so the EMG input makes the combined function, it's called Auto-
reset. See b
NOTE: To avoid non-desired activation problems the system does not allow the alarm
activation inputs to complete the sequence EMG, RST, EMG instantly. The second
consecutive activation will leave about 2 seconds of margin.
c) State output
These outputs are dry contacts that indicate if the equipment is in emergency or failure
state when they are closed. (N.O.)
6
Illustration 6: Fire Central Interface
Illustration : Supervised CIE connection

They allow a maximum current of 350mA and a voltage of 350V.
d) RS-485/MODBUS Interface
Communication port on RS- 85 half-duplex base for communication with fire control
panel. It needs to be connected by 2 twisted wires (A, B) plus a GND wire.
The port uses protocol MODBUS RTU and is used to connect a fire central with
advanced commands. LDA will provide an advanced manual for this function.
2.2.4 Speaker line outputs, zones
The equipment has 6 zone outputs. Each line connection has two terminals + and –
for the speaker connection in 100V or 70 V speaker lines.
The total power of the equipment can be distributed in the departures of zones
according to the design of the installation without exceeding the maximum limit per
output: Zones 1 and 2 500W, Zones 3, ,5,6 120W.
The connection is made by means of a 2-pin female euroblock connector and 5.08mm
pitch (supplied with the equipment). The cable section range for each pole of this
connector is: 0.5 2.5mm2 (22 12 AWG).→ →
NOTE: Connection should be made in order from zone 1 to zone 6, in other case the
Autosetup funcion will not detect correctly the installed lines.
Output voltage (up to 100 V) can be dangerous, so a correct isolation of the speaker
lines in necessary. Test that there are not short circuits, fake contacts or ground
derivations in any of the lines.
a) Backup amplifier
The system has two power amplifier and a switching system who selects the proper
one in each case. When a amplifier fault is detected the system will use only the working
amplifier selecting the higher priority audio, emergency microphone followed by
emergency message have the higher priority.

Illustration 8: Speaker line outputs

2.2.5 Audio source inputs
The system integrates 3 inputs for background music and/or microphones. See the
audio inputs configuration for further details. At the side of each input there is a luminous
audio signal indicator that activates with signal over - 0dBV.
The audio input connection is made by euroblock connectors that allow cable sections
between 0,1 1,5mm2 (30 1 AWG). Input impedance 10Kohm.→ →
a) #1 and #2 Inputs
Inputs for background music or priority
signal. They allow an activation trigger for
each dry contact or signal level, with zone
routing configuration. Input level 1Vrms.
Balanced audio.
b) #3 Input
Configured as a background music
input, because it does not have activation
trigger. Input level is 1 Vrms, balanced
audio input.
c) #4 Input, internal mixer
The system has a # input that has no
external connector, because it is a mixer
integrated in the DSP that uses the 3
inputs. User can configure which one/s
will be in mixer.
2.2.6 ACSI microphones and
devices input
This input allows the connection of up to 8 compatible devices such as MPS-8
microphones or VAP-1 emergency management panels.

Illustration 9: Audio Source Inputs
Illustration 10: PA system devices connection

The ACSI input integrates audio, communications and power allowing the emergency
devices to be fed directly from the integrated backup source.
The connection is made using standard UTP network cable T568B. The connection is
made by bus, with a maximum connection length of 1000m.
This input has a signal indicator LED for audio tests and a state LED that will indicate
that there are connected devices.
2.2.7 LINK output
This connector is intended for the future interconnection of ONE devices.
2.2.8 Pre amplified audio outputs. PRE-AMP OUTPUTS
ONE has outputs at 1 Vrms (line
level) to connect external equipment as
backing amplifiers.
These outputs can be configured to
obtain the same audio as the zones or
as recording output of the messages of
microphones in evacuation.
Connection is made by 3-contact
Euroblock type connectors and 3,81
mm pass (given with the equipment).
Cable section range for each pole of
this connector is: 0,1 1,5mm2 (30 → →
1 AWG). The maximum output load is
10Kohm.
2.2.9 Attenuator cancellation output, OVERRIDE
In the control board there are 6
attenuator override outputs for public
address lines. In idle state they have a
voltage of 0V. In active state, each
output has a voltage of 2 V DC and
20mA of maximum current. Each exit
has two poles.
Connection is made using 2-contact
Euroblock female connectors and 3,81
mm pass (given with the equipment).
Cable section range for each pole of
this connector is: 0,1 1,5mm2 (30→

3 CONFIGURATION AND COMMISIONING
Once made the needed connections, the elements and options used in the system
should be configured.
3.1 Power supply
Before activating system power, test previously service commuters that unable AC
source inputs and battery, see Illustration 3.
Connect the equipment to the electrical network. It should turn on correctly. The front
power indicator lights up and the firmware version will appear on the display during
startup. Then, the start screen will appear.
3.1.1 Install battery charger
The battery charger activation card must be installed, if available, before powering the
equipment.
The memory card includes the battery charging software. It is installed in the micro SD
(b) card connector . Move the metal part following the OPEN arrow and get up. Place the
card, lower the metal tab and move in the opposite direction LOCK to fix it. When the
equipment is turned on, the option to activate the charger and battery monitoring must
appear in the configuration menu.
3.2 Automatic Configuration. <Run Autosetup>
The automatic configuration function saves much of the configuration work of the ONE
system. The operation of the automatic configuration system makes the adjustments
according to what is detailed in the following sections. Any configuration can be
subsequently edited manually.
It is launched by pushing OK button in the option “Run AutoSetup” in the menu
Configuration/System/AutoSetup
This configuration verifies the elements follow EN5 requirements as described in the
following sections.
3.2.1 Date and time
The automatic system tests the configured date, if it is previous to 2010 it will ask the
user to adjust it manually.
3.2.2 Evacuation messages. Messages
System will ask the user if it wants to import messages,(only if USB memory is
connected) asking for the DATAxx directory to import them. Number xx is chosen
between 00 and 99.
Import folders are:
..\DATAxx\EVAC\ for evacuation.
..\DATAxx\ALERT\ for alert.
All the messages in each folder can be imported until the space is filled. Reproduction
order will be alphabetical. If the name coincides, the intern message is overwritten.
Important NOTE: File names should have a maximum of 8 characters with no spaces
nor spCIEal characters (simbols) with the “.wav” extension.
11

File format is monochannel 16 bits PCM with sampling at 2 or 8 Khz
LDA offers a free tool to convert audio files, you can find it int our support web page.
3.2.3 Advanced mode question
The system ask about advanced mode yes or not option. In advanced mode user will
be able to select A+B speaker lines configuration. Once selection is done system will
follow these steps to self-configure.
a) Zones and speaker lines. Zones
The system checks automatically the loudspeaker lines, looking for the ones that are
being used. They must be connected in order since when the equipment detects a line
with impedance higher than the measurement range (600 Ohm), it considers that neither
this line nor the following ones will be used.
When the user wants to use a line with high impedance (more than 600 Ohm), install
an end of line terminal (LDATFL2) in order to let the equipment recognize it as a zone in
use. All the detected zones are configured with active line supervision, but this can be
changed from the menu Configuration/Zones.
Using the active line supervision volume controllers cannot be used, because the input
impedance varies depending on the adjusted level.
b) CIE Interface (Fire Detection Central)
The system checks that the inputs are connected correctly with the specified
terminators (2.2.3). When it detects the end of line (EOL) devices the supervision of the
general input and/or the connected zone inputs will get activated. If the EOL devices are
not detected they will remain active without supervision, working in dry contact mode.
c) Battery
Battery management depends on the installation of the charger accessory EN5 - .
The system checks if the microSD card is installed with the charger module. In this case,
the system will check that there is an installed battery, checking the voltage and the
internal impedance. Minimum working voltage is 10,5 V with a maximum impedance of
200mOhms. We recommend to adjust impedance according to installed battery once
this is 100% charged.
d) ACSI devices
Connected ACSI devices always are automatically detected after some seconds.
Using the automatic configuration they remain installed in the system so that a failure will
appear later if any Voice Alarm Panel (VAP) or microphone (MPS) get disconnected.
It should also be tested that the devices addresses are correctly configured and that
the end of line device of the last bus device is active.
e) Backup amplifier
The backup amplifier is activated automatically and amplifier supervision too. It will
show failure if in any moment any of them stops working or does not offer the gain level
calibrated.
f) Setup Report
Once auto setup is finished screen will show the number of zones and lines installed
and ACSI devices detected. Check this info and configure manually if necessary.
