U-60 – Aerosol Fire Extinguishing Device for Lithium Batteries

What is LiGUARD R-10?

LiGUARD R-10 is a heat-activated aerosol fire suppression device designed for local protection of enclosed electrical and technological cabinets. It is a passive autonomous module that activates without any external power supply.

The device is not a portable fire extinguisher according to EN 3 and does not replace building-level fixed fire suppression systems.

Who is the device intended for?

The product is intended primarily for:

• facility and technical equipment managers

• electricians and inspection engineers

• photovoltaic system operators

• IT and server room operators

• industrial maintenance teams

• electrical wholesalers and distributors

• system integrators and installers

What is the purpose of the device?

The purpose of the module is to limit or suppress the early stage of a fire inside an enclosed cabinet and to reduce the risk of fire spread beyond the protected space.

How does LiGUARD R-10 operate?

When the activation temperature of approximately 170 °C is exceeded, the device automatically releases an aerosol into the protected enclosure. The aerosol interferes with the combustion process and reduces temperature.

The device operates without pressurised vessels and contains no electronics.

Does the device require electrical power?

No. The device is fully autonomous and activated solely by temperature.

In what environments may R-10 be used?

The device is intended exclusively for enclosed spaces such as:

• low-voltage and DC distribution cabinets

• circuit breaker panels

• UPS enclosures

• battery boxes installed inside cabinets

• control and automation panels

It is not intended for open areas or for protecting entire rooms.

What cabinet size can one module protect?

The protected volume depends on cabinet construction, sealing, and ventilation. For larger or ventilated cabinets, professional system design and the use of multiple modules are recommended.

How is the device installed?

The module must be fixed inside the protected enclosure in accordance with the manufacturer’s installation instructions. The aerosol outlet must not be obstructed and a free clearance zone must be maintained in front of the discharge port.

Installation by a qualified person is recommended.

Is the device maintenance-free?

The device does not require active servicing. Visual inspection during routine cabinet inspections and verification of manufacturing date and service life are recommended.

What is the service life?

The nominal service life is 10 years from the manufacturing date or until activation, whichever occurs first.

What actions are required after activation?

After discharge, the device is no longer functional and must be replaced. Inspection and cleaning of the protected enclosure by qualified personnel is recommended before re-energising equipment.

Does the aerosol damage electronics?

The aerosol agent is designed for use in electrical enclosures. After discharge, professional cleaning of the cabinet is recommended.

What standards and certifications does the device comply with?

The device has been tested in accordance with:

• EN 15276-1:2019

• EN 15276-2:2019

and is included in an EC Declaration of Conformity under Directive:

• 2014/68/EU (Pressure Equipment Directive)

Who is the manufacturer and the EU responsible economic operator?

Manufacturer: Dongguan Feng’an Security Technology Co., Ltd.
EU responsible economic operator: ENERO s.r.o., Slovakia.

Is the device suitable for lithium battery systems?

The device is intended for local protection of enclosed battery and electrical cabinets. For larger battery energy storage systems, a dedicated multi-layer fire protection design is recommended.

Can the device replace the fire protection system of a building?

No. The module is a supplementary local protective measure only. It does not replace mandatory building fire safety systems or fixed suppression installations.

Is the product suitable for distributors and system integrators?

Yes. The product is supplied for professional distribution channels and system integrators. Technical documentation is available for partners.

Are project quantities available?

Yes. Volume pricing and project-based supply are available for B2B customers and distributors.

Is technical support provided?

Yes. ENERO s.r.o. provides technical consultation, assistance with system design, and documentation for engineers, insurers, and authorities.
