A mobile and rapidly deployable solution

The EPA is designed to be transported in a vehicle and then put into service quickly when a situation requires warning or informing the population.

The loudspeaker and its light signaling are positioned on the vehicle using a magnetic base.

The control unit remains accessible inside the vehicle, allowing for operation of the siren, selection of recorded messages, and use of the microphone.

No fixed installation is required.

The equipment can thus be used temporarily on different compatible vehicles as needed.

Siren, microphone, and recorded messages

The Portable Alert System combines several functions:

  • 112 dB siren;

  • orange or blue light signaling, depending on the version;

  • flashing or rotating signal;

  • external loudspeaker with magnetic attachment;

  • microphone;

  • Public Address function;

  • up to 3 recordable voice messages;

  • message storage on Micro SD card.

The system thus allows for the broadcasting of an alert tone, a pre-prepared message, or an announcement made directly by the operator.

3 pre-recorded messages

The EPA allows up to 3 voice messages to be recorded on a Micro SD card.

They can be prepared for different situations:

  • evacuation;

  • taking shelter;

  • flooding;

  • fire;

  • industrial risk;

  • weather event;

  • closing of an area;

  • safety instructions;

  • information intended for the population.

The Public Address function also allows you to speak directly into the microphone when a message needs to be broadcast immediately.

For municipalities and local authorities

The EPA is particularly suitable for municipalities with a Communal Safeguard Plan (PCS) that need a mobile means to broadcast an alert or instruction to the population.

A vehicle equipped with the EPA can drive through the affected areas while broadcasting:

  • a siren;

  • a pre-recorded message;

  • a microphone announcement;

  • light signaling.

Its portable design allows it to be deployed quickly without immobilizing a dedicated vehicle.

For campsites

The Portable Alert System is also suitable for campsites and outdoor establishments that need a mobile means of information and alert.

A vehicle can drive through the establishment while broadcasting instructions or messages to the occupants.

The orange SNA versions are particularly adapted to this use.

National Alert Signal

Several versions are equipped with the National Alert Signal (SNA) tone.

The versions concerned are:

  • EPA Blue Flashing SNA – ref. 28874;

  • EPA Orange Flashing SNA – ref. 27780;

  • EPA Orange Rotating SNA – ref. 31217.

The system also allows for the broadcasting of the all-clear signal and other tones depending on the chosen configuration.

Vehicle installation

The EPA does not require permanent vehicle modification.

The external device is attached via a magnetic base and the various elements are connected using the provided cords.

Power is supplied directly from the vehicle.

The unit can then be dismantled and stored in its case after use.

Regulations

The use of certain blue light signaling and certain sound tones is regulated.

The technical homologation of the equipment does not in itself constitute an authorization to use it on any vehicle.

It is the user's responsibility to select a configuration compatible with their activity and the applicable regulatory framework.

Frequently asked questions about the EPA / EMA Portable Alerting System

What do the abbreviations EPA and EMA mean?

EPA is the French abbreviation for Ensemble Portatif d’Alerte, meaning Portable Alerting System. EMA stands for Ensemble Mobile d’Alerte, meaning Mobile Alerting System. Both terms refer to this transportable vehicle-mounted warning system.

In which situations can an EPA / EMA be used?

The Portable Alerting System attracts attention and broadcasts instructions near a vehicle. It combines warning lights, a siren and voice broadcasting for public information operations, emergency situations and safety exercises.

Who is this equipment intended for?

The system is particularly suitable for local authorities, municipal departments and campsite managers requiring a mobile solution for broadcasting instructions. The version must be selected according to the intended duties, the vehicle and the authorised conditions of use.

What is supplied with the Portable Alerting System?

The equipment includes the components required for operation:

  • A storage and interconnection case.
  • A magnetic loudspeaker with warning light.
  • A control unit with integrated microphone.
  • A Micro SD card for recorded messages.
  • Coiled connection cables.
  • A cigarette-lighter power supply with an On / Off control.
Does installation require any permanent modification to the vehicle?

No. The system is designed for use without permanent installation. The loudspeaker has a magnetic mounting base and the power supply connects to the vehicle socket. The mounting surface must be compatible, and installation must comply with the equipment instructions.

Can the same system be shared between several vehicles?

Yes. Its portable design allows the system to be moved from one vehicle to another, provided that each vehicle has a suitable power supply and compatible mounting surface. The case keeps all components together between uses.

Does the EPA / EMA operate with a 12 V or 24 V power supply?

The operating range is 10 to 30 V DC, covering 12 V and 24 V vehicle power supplies. The stated maximum consumption is 6 A at 12 V or 3 A at 24 V. The power supply is protected by a 10 A fuse.

How can live instructions be broadcast?

The microphone integrated into the control unit allows the operator to speak directly to the public using the Public Address function. Announcements can therefore be adapted immediately without preparing a recording. The volume is adjusted from the control unit.

Can several announcements be prepared in advance?

Yes. The system can store up to three voice messages on a Micro SD card. The operator selects the required announcement from the control unit. This function is useful for preparing recurring instructions for an operation or safety exercise.

What sound level does the siren provide?

The stated sound level is 112 dB. This value alone does not determine an audible range: background noise, obstacles and terrain conditions affect how the signal is heard and how clearly messages can be understood.

Which warning light and siren combinations are available?

Four configurations are available for different requirements:

  • Blue flashing light with SNA tone.
  • Amber flashing light with SNA tone.
  • Amber rotating light with SNA tone.
  • Blue rotating light with Police tone.

Specify the required configuration when submitting your request. The appropriate choice depends on the intended use and the applicable authorisations.

What does the SNA tone mean?

SNA stands for Signal National d’Alerte, the French National Alert Signal. The corresponding configurations can broadcast this signal and the end-of-alert signal. These tones are separate from customised voice messages and cannot be modified by the user.

How should I choose between a blue and an amber version?

The choice must take account of the user department, vehicle and intended duty. Blue warning lights and specific tones are subject to conditions of use: purchasing the equipment does not constitute authorisation to use it. Tell us about your requirements so that we can direct you to the appropriate configuration.

What are the dimensions of the stored system?

The equipped case measures 32 × 23 × 15.5 cm and weighs approximately 4.10 kg. The magnetic loudspeaker measures approximately 18 × 13 × 21 cm and weighs approximately 1.14 kg.

How long are the connection cables?

The coiled cables measure approximately 0.5 m when retracted and can extend to 3 m. This allows the components to be positioned around the operating area while keeping them compact during storage.

Does the system have an automatic shut-off function?

Yes. The system has an automatic shut-off after three hours of inactivity. This is a shut-off period and not a battery operating time: the equipment uses the vehicle’s power supply.

Where can I find the technical documentation?

The documentation presents the equipment and specifications of the blue and amber versions. You can view the EPA technical data sheet in PDF format to help prepare your choice. The PDF is currently available in French.

How can I request a quotation for a Portable Alerting System?
