le 0.4 ampere current thermal activation is a new invention for activating the fire suppression systems. It is specifically designed to activate our aerosol fire extinguishing devices, or to activate other fire extinguishing devices that do not exceed 0.4 amps.
This product has a built-in safety switch (interrupteur de maintenance) that can be turned to the « off » position when you are working on an installation, so that you don’t activate the extinguisher by mistake during the installation. When the installation is complete, turn the safety switch to the « on » position.
It also has a signal feedback (pressostat) function where you can set the feedback signal (pressostat) de « N/O » à « N/C ». It usually connects with the fire alarm system or the control panel.
The fusible metal on the top of the product is a temperature sensing probe that can detect temperatures of 70 degrés, 93 degrés, 110 degrés, 125 degrés, et plus. We can customise the temperature probe and set any start-up temperature according to the customer’s specific requirements.
This product is relatively low-cost and is mainly for our extincteurs aérosols. It is directly connected to the aerosol (MiniSol) to form an automatic fire extinguishing system without any external power supply.
When the temperature of the temperature probe of the thermal detector reaches the rated value after being heated, the fire extinguishing device will be activated immediately, with an activation lag time of less than 1 seconde.
The Basic Parameters of the Thermal Activation Device
To give you a better understanding of this product, dans ce qui suit, we will introduce the basic parameters of this product one by one:
- Nom du produit: Thermal detector, Dispositif d'activation thermique.
- Modèle No.: AW-TG70-G4, or AW-TG70-G4B.
- Current generated: 0.4 amps.
- Service objects: Aerosol fire extinguishers and other products with a current not exceeding 0.4 amperes.
- Taille: φ60*67mm without ear, installation ear length 12 mm.
- Couleur du produit: blanc.
- Electric Cable Wire Length: 0.3 mètre réglable.
- Detection temperature of the temperature-sensitive probe: 70℃, 93℃, 110℃, 125℃.
- Probe material: Fusible tin metal.
- Safety switch material: 304 acier inoxydable.
- Installation ear hole dimension: M7.
- The basic composition of the product: métal fusible, safety switch, ABS plastic shell, 304 coque en acier inoxydable, copper coils (or battery), magnets, cartes de circuits imprimées, fils, etc.
- Installation tools: des vis.
Mounting location: ceiling (top) or inside wall.
- Température ambiante: -40℃ to +110℃. Adjustable according to start-up temperature requirements.
- Humidité relative: 95% sans condensation.
We have a detailed instruction manual. for specific details, please check and refer to the contents of our manual.
Par rapport à its predecessor, this new temperature starter has the following features:
- Lower height, the height of the previous generation is 139 mm, the height of this product is 68 mm, making it easier to install in narrow spaces.
- The product does not require an additional junction box, saving installation space and production costs.
- Copper coils are smaller and produce less current, but are cheaper to produce and more affordable.
- More selective, to increase the output current, we can replace its internal components with lithium batteries or lithium ternary batteries, so that you can start the fire extinguishing system with high current requirements.
Bref, this product is relatively inexpensive, in addition to meet basic start-up functions. It is ideal for price-sensitive customers.
This product normally works with our small aerosol fire extinguishing generators.
It is the same as an aerosol, and it has the same areas of application as an aerosol.
We list some of the main applications:
- armoires électriques.
- Les panneaux de commande.
- ESS energy storage containers.
- Packs de batterie au lithium.
- Salle des générateurs diesel.
- Moteur de voiture.
- Wind turbine nacelle.
En raison de la petite taille de ce produit, it can be easily installed in tight spaces.
Actuellement, it is used more on distribution cabinets and wind turbine nacelles.
The specific design needs to be decided according to the size of the installation space.
The temperature probe of this product is sensitive, so pay attention to the following when storing it:
- Do not store in excessively hot areas, especially indoor temperatures that do not exceed the rated melting temperature of the probe.
- Set the safety switch to the "OFF" position before installation to prevent activation of the fire extinguisher by mistake.
- Copper coil-started models have a life-time of 10 années, but the longevity of battery-started models needs to be determined by the life of the batteries. When the batteries are depleted, you need to replace them with new batteries.
