Heat-Activated Fire Suppression
The UH-ES-AFD01 uses a thermal activation mechanism to initiate aerosol discharge when the specified activation conditions are reached. Its automatic operation is intended for localized protection in suitable enclosed electrical equipment spaces.
Compact Enclosure Installation
The compact design allows the device to be considered for small electrical cabinets and equipment enclosures where installation space is limited. Mounting position, available clearance and internal obstructions must be evaluated before installation.
Condensed Aerosol Technology
The device uses a solid aerosol-forming compound to generate a fire-suppressing aerosol upon activation. The non-pressurized generator design provides an alternative to conventional stored-pressure extinguishing equipment for appropriately evaluated applications.
Electrical Equipment Applications
The UH-ES-AFD01 is intended for supplemental fire suppression in suitable distribution cabinets, control panels and equipment compartments. Its use should be evaluated according to the enclosure construction, fire hazards and applicable project requirements.

Installation
Installation Guidance
1. Confirm that the protected enclosure and intended application are suitable for the device.
2. Ensure electrical equipment is safely isolated before installation work.
3. Select a mounting position according to the manufacturer's installation instructions.
4. Keep the aerosol discharge path clear of obstructing components.
5. Verify that the device and its activation components will not interfere with normal equipment operation.
6. Check the installation against the approved mounting instructions before the equipment is placed into service.
**Important:** Installation must follow the instructions supplied with the production unit. Do not dismantle, modify, heat or deliberately activate the device during installation.
Important Notes
The UH-ES-AFD01 is intended for supplemental fire suppression in suitable small electrical enclosures. Its suitability depends on actual installation conditions, protected volume and project-specific fire hazards.
It should not be considered a direct replacement for required electrical protective devices, fire detection systems or building-level fire protection.
Use in battery thermal runaway applications, occupied spaces or other specialized environments requires appropriate application-specific validation. Product documentation and destination-market requirements must be reviewed before ordering.
FAQ
Frequently Asked Questions
What is an aerosol fire extinguishing device?
An aerosol fire extinguishing device uses an aerosol-forming compound to generate a fire-suppressing aerosol upon activation. The UH-ES-AFD01 is intended for suitable small electrical enclosures.
Does the UH-ES-AFD01 require external electrical power to activate?
The product is described as heat-activated. The activation configuration and installation requirements should be verified against the documentation supplied with the production unit.
Where can this product be installed?
It can be installed inside suitable enclosed spaces such as electrical cabinets, control boxes, communication cabinets, combiner boxes, inverter enclosures, and similar equipment compartments.
Can this product be used in large spaces?
This product is intended for small enclosed spaces. For larger cabinets, multiple compartments, or open areas, the suitability of one device must be evaluated according to the enclosure volume and fire-protection design.
Can it replace a room-level fire protection system?
No. The device is intended for localized enclosure protection. It should not automatically be considered a replacement for building-level fire alarms, extinguishers, or other required fire-protection systems.
Is an EN 15276-1:2019 test report available?
Yes. A third-party test report for the corresponding AFED product model is available upon request. Applicability to the intended project and destination market should be confirmed before ordering.
