Automatic aerosol fire extinguishing device | 150g | 5-24VDC / 170°C activation | 1.5m³

The 150g version is intended for larger electrical and automation cabinets and other enclosed technical spaces. The module is mounted with brackets to the inner wall of the panel, so it does not occupy DIN rail space and can be installed separately from other modular components.

The thermal line is designed for automatic activation of the extinguishing module. When directly exposed to flame or when the temperature at the activation point reaches approximately 170±10°C, the module activates automatically. This activation method does not require a signal from an external fire detector or controller.

For electrical activation, the extinguishing module is used together with a fire detector and controller. When the detector identifies signs of fire, the signal is transmitted to the controller, which activates the aerosol fire extinguishing module. The activation voltage may range from 5V to 24V DC, while the activation current must be greater than 350mA.

For electrical activation, 5–24V DC voltage alone is not sufficient. The activation circuit must be capable of supplying more than 350mA. Before connecting the module, it is essential to verify that the controller output meets both requirements.

One 150g module is designed to protect a volume of up to 1.5m³ when the extinguishing density is 100g/m³. When selecting the device, the actual internal volume of the protected space, ventilation openings, leakage, component arrangement and other installation conditions must be evaluated.

The module has a cylindrical housing with dimensions of Φ76x139mm. It is mounted with brackets to the inner wall of an electrical panel or technical cabinet. This installation method makes use of the cabinet's vertical surfaces and keeps the DIN rail space available for other electrical and automation equipment.

The 150g aerosol module is designed for local fire protection in enclosed technical spaces up to 1.5m³. Its cylindrical construction and bracket mounting to the cabinet wall allow the module to be used in larger electrical distribution, automation, variable frequency drive and other technical cabinets, provided that their volume and construction comply with the product's conditions of use.

• Protected volume up to 1.5m³ is suitable for larger enclosed electrical and automation cabinets.
• 150g of extinguishing agent and an extinguishing density of 100g/m³.
• Two activation methods – automatic thermal and electrical.
• Automatic thermal activation allows the module to activate when the thermal line is exposed to flame or reaches approximately 170±10°C.
• 5–24V DC electrical activation allows the module to be integrated into fire detection and control systems.
• Activation current >350mA defines the requirement for the controller activation output.
• Bracket mounting to the cabinet wall does not occupy DIN rail space.
• Cylindrical Φ76x139mm housing is designed for stationary installation inside a technical cabinet.
• Wide operating temperature range from -50°C to +90°C.
• Ambient relative humidity up to 95% RH allows use under various technical environmental conditions.
• 10-year service life is designed for long-term stationary protection.

• Protected volume limit: one module is designed for an enclosed space of up to 1.5m³, therefore larger volumes require a separate engineering assessment.
• Additional equipment required for electrical activation: the module must be used together with a suitable fire detector and controller.
• Sufficient output current is required: 5–24V DC voltage alone is not sufficient – the controller activation output must be capable of supplying more than 350mA.
• Mechanical fastening is required: due to the 880g weight, the module must be securely mounted with suitable brackets to a structurally suitable panel wall.
• Single-use operating principle: after actual activation, the aerosol generator must be replaced with a new one.
• Importance of enclosure tightness: ventilation openings, leakage and intensive air exchange may affect the aerosol concentration in the protected space.
• Not a whole-room fire suppression system: the product is intended for local fire protection of an enclosed technical space.

The internal protected volume of a larger automation cabinet is approximately 1.25m³. The cabinet contains circuit breakers, contactors, variable frequency drives, power supplies and control electronics. The 150g aerosol fire extinguishing module is mounted with brackets to a suitable inner wall of the cabinet. The thermal activation line is positioned within the protected area, allowing the module to activate automatically if the line is directly exposed to flame or its temperature reaches approximately 170±10°C. In addition, the device can be connected to a fire detector and controller. For electrical activation, the controller must send a 5–24V DC signal and provide an activation current greater than 350mA.

One 150g module is designed to protect an enclosed technical space of up to 1.5m³ when the extinguishing density is 100g/m³.

The module is mounted with brackets to the inner wall of an electrical panel, automation cabinet or other suitable technical enclosure.

No. This model is mounted with brackets to the panel wall, so it does not occupy DIN rail space.

The module can be activated automatically by the thermal activation line or electrically through a 5–24V DC activation circuit.

When the thermal line is directly exposed to flame or its temperature reaches approximately 170±10°C, the extinguishing module activates automatically.

No. The thermal activation line can activate the module independently in response to flame or high temperature.

The module is used together with a fire detector and controller. When the detector detects a fire, the controller sends an electrical activation signal to the extinguishing module.

The electrical activation voltage may range from 5V to 24V DC.

The activation current must be greater than 350mA.

No. Both the output voltage and current capability must be checked. The controller output must be within the 5–24V DC range and capable of supplying more than 350mA.

The module contains 150g of aerosol-generating chemical agent.

The module dimensions are Φ76x139mm and the product weight is 880g.

The operating ambient temperature range is from -50°C to +90°C.

The ambient relative humidity may be up to 95% RH.

The product service life is 10 years when the manufacturer's installation, storage and operating conditions are followed.

No. The aerosol fire extinguishing generator is a single-use device and must be replaced with a new one after activation.

The aerosol fire extinguishing module must be selected and installed according to the manufacturer's technical documentation, the actual volume of the protected space, ventilation openings, leakage, equipment arrangement, fire risk and applicable fire safety requirements. For electrical activation, the controller activation circuit must be 5–24V DC and capable of supplying more than 350mA. The 880g module must be securely mounted with suitable brackets to a structurally suitable panel or cabinet wall. The thermal activation line must be positioned according to the manufacturer's installation instructions. The device must not be dismantled, mechanically damaged, heated or activated other than for its intended purpose. After activation, the product must be replaced with a new one.
