supply. Be sure to use the proper cables to make the connections.

1 INTRODUCTION

LDA ONE PA/VA system is certified according to EN 54-16 and EN54-4 requirements,

ensuring a safe and controlled emergency evacuation. Its high performance, versatility and

audio quality make it a powerful and affordable music and voice distribution system for all

kinds of installations. This User Manual is applicable from FW version v02.00.01.00

onward.

Range of products and accessories for ONE:

•ONE 500. Expandable VA central module.

◦ONE-BC: Battery management module according to EN54-4

◦ONE-LOOP: Expansion card for multi-device distributed systems.

•TFL2. Speaker Line terminator.

•MPS-8Z. Expandable 8-zone microphone station.

•VAP-1. Voice Alarm Panel with optional zone selection.

Other accessories:

•ONE-WMA Wall Mount Brackets and ONE-RMA rack.

1.1 System characteristics.

Each ONE unit consists of an EN54-16 system capable of controlling a maximum of 6

zones and delivering a maximum total power of 500W. In addition, it is possible to create

larger systems by linking several ONE units, allowing the control of up to 60 zones with an

overall power of up to 5000W.

Characteristics of each ONE unit:

•Up to 6 zones

•6 amplified audio outputs for speaker lines

•4 pre-amplified audio outputs

•3 physical audio inputs, 2 of them with dynamic request for speech

•1 internal mixer that can generate an additional MIX source from the 3 physical

inputs

•ACSI port for connection of up to 8 microphones or fire panels

•Internal memory for evacuation and alert messages, organized in 2 independent

playlists

•Interface for connection to fire stations (ECI / CIE):

◦Activation inputs and global reset of the emergency

◦Zonal emergency activation inputs

◦Outputs of information on emergency status and system fault

◦RS485 / Modbus serial integration port

•6 attenuator override outputs (24V override)

ONE Extended System Features:

•Connection of up to 10 ONE devices with redundant communication link

•Up to 60 zones

•ACSI port for connection of up to 8 microphones or fire panels, with access to each

zone of the extended system

•Monitoring of the emergency system from any ONE unit

•Manual control of the evacuation system from any device or fire panel in the system

•Distribution of global audio sources, generated from the main unit:

◦System general audio sent from the MIX of the main unit to other units of the

system

◦ACSI microphones and fire panels, both for public address messages and

evacuation operations

•In addition to the integrated functions, each unit meets the mandatory requirements

of the EN54 standard and has its own functions:

◦Exclusive and independent emergency messages

◦Emergency activation inputs per zone

◦Independent emergency power

◦For public address use, each unit has 1 audio input for music (Input 3) and 1

microphone input with priority (Input 1)

◦Input 2 receives the audio from the main unit and forwards it to the next unit

1.2 System diagram

The system will always consist of a main or master unit which will receive the

connection of ACSI bus and its devices. Optionally, a system can be made up of more than

one unit. In this case, the first unit must have a redundant system link card (ONE-LOOP)

installed in its expansion bay. For more information on the connection of these types of

systems and their configuration, see respectively section 2.2.11 and section 3.5.

Figure 1: Example of a system with 3 units

1.3 HW and FW versions

For the operation of the expanded ONE system, ONE devices must have a serial

number over 20xxxxxx and have their firmware updated to version v02.00.01.00 or higher.

You can check for firmware updates on the LDA support website.

1.4 User interface description

The device has a manual control interface, which will serve as an information and

control point for the system user. A view of this element, which will be described in the

following sections, is shown in figure 3.

1.4.1 Light indicators

The status indicators show the operating condition of the unit or system at all times.

They are located on the left of the screen.

Figure 3: Control panel

Figure 2: Inside view

a) PWR: “POWER” / “ENERGÍA”. Green

On: when the device is powered from any of the possible power sources.

b) EMG: “EMERGENCY” / “EMERGENCIA”. Red

On: when the system is in an emergency operating status (voice alarm), either by

manual or automatic activation from the CIE (Control and Indicating Equipment) from any

of the available emergency inputs.

Along with the indicator lighting up, a continuous audible warning will be emitted. This

warning can be silenced by the “BCK” button.

c) FLT: “FAULT” / “FALLO”. Amber

On: When the system is in a fault status. This indicator is automatically activated upon

fault detection of any of the supervised functions.

Along with the indicator lighting up, an intermittent audible warning will be emitted. This

announcement can be silenced by the “BACK” control, or automatically when the

emergency microphone is used.

d) SYS: “SYSTEM FAULT” / “FALLO SISTEMA”. Amber

On: when there is a fault in the execution of the software of the unit, or in its memory.

Reset the fault condition. If the problem persists, please see section 5.1.7.

1.4.2 Alphanumeric display

This screen, based on a 2-line, 16-character alphanumeric display, will serve to show

the device configuration menus. Likewise, it will offer expanded information on the system

that is not expressly included in the light indicators such as, among others, zonal statuses

of emergency and fault.

1.4.3 Controls

a) Scrolling controls

They are located on the right of the display. They

allow navigation through the use and configuration

menus. The central button allows the ENTER/OK

function, in order to access the menu and for

operations requiring confirmation.

Figure 4: Interface buttons

b) Direct access controls

i) ENTER/OK: Press for 2 seconds to perform the test of the indicators.

ii) RESET/RST: Press for 2 seconds to allow the restart of the system operating

condition, when it is in emergency or fault status.

iii) BCK:

•Menu navigation: go up one level / go back. If pressed for 3 seconds, the unit

will return to the initial screen and restart the access level (log-out).

•It silences the acoustic buzzer when it is playing (ACK function)

1.5 User profiles. Access level. Passwords

The access levels define the different user profiles that can operate with the unit /

system. Each of the access levels has permission to enter different menu options, with

level 1 having the smallest number of options available and level 5 having the largest

number of options available.

Generally, access levels allow:

•Level 1 (L1): Visualization of elements according to EN54 and use of PAsystem1

•Level 2 (L2): System management and emergency functions. Password2: 0002

•Level 3 (L3): System configuration and advanced functions. Password2: 0003

•Levels 4 and 5 (L4 and L5): Only accessible by the manufacturer.

In some screens, the access to some functions is allowed only to authorized level users.

A user with a higher level password will be able to access lower level functions.

To access a certain level or to configure the access mode, use the Login menu (see

section 3.4). You can select between access by confirmation, or access by 4-digit

password.

The login has a validity time of 5 minutes, it can be reduced by pressing the BCK button

for 2 seconds, then it will return to user level home screen 1.

1 PALock: A password access can be optionally configured for PAcontrols (volume, routing, etc.). See

section 3.4.

2 This is your default password, which can be modified using the corresponding configuration menu (see

section 3.4).
