Public address and voice alarm systems for logistics centers

At LDA we are experts in public address and voice evacuation systems for logistics centers. That’s why we can help you create the most competitive solution that best suits your needs.

Sound environment for logistics centers

Large areas dedicated to logistics should be secured with a good PA/VA system for the peace of mind of the workers . Their public address systems therefore need to offer an appropriate sound atmosphere and at the same time ensure fast evacuation and escalation by priority zones in case of emergency.

It’s a given that people act faster when they hear a human voice telling them what to do or how to proceed, especially in case of emergency.

LDA Audio Tech’s public address and voice alarm systems certified according to EN 54 and EN 60849 provide intuitive user management and are easily integrated with existing third-party technologies in logistics centers.

PUBLIC ADDRESS SYSTEM

The public address system in logistics centers allows voice messages to be sent to all areas to help organize work, manage priorities, facilitate communication between sections, etc.

 

The advantages of an LDA public address system are the following:

  • Possibility of sounding different areas with high quality.
  • Management of messaging and background music. Possibility of remote supervision and management of the system by tablets.
  • Possibility of addressing messages to specific areas to locate workers, warn of the arrival of trucks, communicate alerts, etc.
  • Establish communication between the different sections of the logistics hub to increase the effectiveness of workers.
  • Management of messages through the calendar module. Distribution of pre-recorded messages, announcements, as well as automation of safety messages.
  • Possibility of managing several logistics hubs interconnected through the network.

VOICE EVACUATION SYSTEM

A voice evacuation system is a critical safety tool that allows us to achieve a faster, more controlled and safer evacuation that can save lives.

 

The European standard EN 54 sets out the requirements for fire detection and alarm systems throughout the European Union. In addition, it has been adopted in numerous international markets as a standard that guarantees safety for people in the event of an emergency.

 

In those buildings where loudspeakers are used to emit voice alarms in the event of fires in Spain, compliance with the EN 54-24 application standards for loudspeakers and EN 54-16 for the systems to which they are connected is mandatory.

 

In addition, the Technical Building Code establishes basic quality requirements that must be met by buildings, including their facilities, in order to satisfy basic safety and habitability requirements. Article 11 establishes the basic safety requirements in case of fire (SI):

 

“The objective of the basic requirement ‘Fire Safety’ is to reduce to acceptable limits the risk that the users of a building will suffer resulting from an accidental fire, as a consequence of the characteristics of its design, construction, use and maintenance.

 

“To meet this objective, buildings shall be designed, constructed, maintained and used in such a way that, in the event of fire, the basic requirements set out in the following paragraphs are met:

  • Internal propagation: The risk of propagation of the fire inside the building will be limited, both to the same building and to other adjacent buildings.
  • External propagation: The risk of propagation of the fire by the exterior shall be limited, both in the building under consideration and to other buildings.
  • Evacuation of occupants: The building shall have adequate means of evacuation to make it easier for occupants to leave it or to reach a safe place within it under safe conditions.
  • Fire protection installations: The building will have the appropriate equipment and facilities to make possible the detection, control and extinction of the fire, as well as the transmission of the alarm to the occupants.
  • Fire brigade intervention: The intervention of the rescue and fire extinguishing teams will be facilitated.
  • Structural fire resistance: The load-bearing structure will maintain its fire resistance for as long as necessary to meet the above basic requirements.”

 

The advantages of an LDA public address and voice evacuation system can be summarized in the following points:

  • It allows you to broadcast both live voice by microphone and different pre-recorded voice messages to any area or set of selected areas.
  • Report on the type of incident.
  • Generate a quick reaction in people.
  • A voice alarm improves the response time in evacuation of buildings by generating a rapid reaction in people.
  • Reduce panic.
  • Perform a directed and phased evacuation, according to the evacuation plan of the building.
  • Indicate the quickest and safest way

 

With regard to the management advantages of LDA systems, the following should be highlighted:

  • Modern equipment, so the system has no obsolescence problems.
  • Complete supervision of all elements of the system, which provides high availability and a higher degree of security to the system.
  • Redundancy of the elements of the system, thus reducing the level of system errors.
  • Implication of civil liability insurance, as it is a system with a higher degree of security.

 

On the other hand, evacuation signal processing can be carried out in different ways:

  • Through interfaces with the fire detection system.
  • Through the data network, through interfaces that allow us to connect to it.
  • Through the control signal

 

In addition, from 2019 the integration between the NEO and ONE systems will be possible. This will allow NEO to be used as a global evacuation system in logistics centers and ONE as a local evacuation system in each of the units.
