How FireKavach Works

FireKavach works through a condensed aerosol fire suppression mechanism. When ambient temperature inside the enclosure where it's mounted reaches approximately 170°C, an internal heat-sensitive element triggers the release of a fine fire-suppressing aerosol that fills the enclosed space.

This aerosol interrupts the chemical chain reaction of combustion at a microscopic level, rapidly reducing the fire's ability to sustain itself. Because the entire process — from detection to suppression — is thermal and mechanical, no electricity, batteries, sensors, or external triggers are involved.

FireKavach activates automatically via a heat-sensitive trigger mechanism that responds when the surrounding temperature reaches approximately 170°C. This temperature threshold is calibrated to correspond to the early stages of an active fire or severe overheating event inside an enclosed electrical panel — well above normal operating temperatures, but early enough to suppress the fire before it spreads.

No — FireKavach does not need wiring, electricity, or battery backup of any kind. It is a fully passive device whose only "input" is ambient heat. Installation involves mechanically mounting the unit onto the DIN rail — there are no electrical connections to make, no power supply to provide, and nothing to charge or replace on a schedule.

Yes — FireKavach works during power failure because its activation mechanism is entirely independent of electrical power. It relies solely on ambient heat from the fire itself, so a loss of mains power, battery backup, or any electronic system has no effect on its ability to detect and suppress fire.

This is particularly relevant because electrical fires often occur alongside power faults — a device that depends on power to function could be compromised at the exact moment it's needed.

FireKavach should be installed inside the electrical enclosure you want to protect — mounted on the standard 35mm DIN rail alongside MCBs, contactors, or other modular devices. This includes DB boxes, distribution panels, ACDB/DCDB enclosures, PDUs, and control cabinets.

The device can be installed horizontally or vertically depending on the orientation of the DIN rail within the enclosure, giving flexibility for different panel layouts.

FireKavach's coverage area depends on the model — Mini is sized for standard DB boxes and small enclosures, while Macro covers larger panel volumes. Choose the model based on the enclosed volume of the panel being protected.

Both models are designed for single-use activation: once the unit has discharged to suppress a fire, it has fulfilled its function and should be replaced, similar to how a traditional fire extinguisher is recharged or replaced after use.

FireKavach requires minimal maintenance — primarily periodic visual inspection to confirm the unit is undamaged and securely mounted on the DIN rail. There are no batteries to replace or electronic components to test.

FireKavach is not reusable after activation — once it has discharged its aerosol to suppress a fire, the unit should be replaced. This is consistent with how single-use fire suppression devices generally function.

After FireKavach activates, it releases its fire-suppressing aerosol into the enclosure to extinguish the fire. The aerosol is formulated to be non-conductive and designed not to leave a corrosive residue on electrical components.

Following activation, the panel and any components affected by the original fault should be inspected by a qualified electrician before being returned to service, and the activated FireKavach unit should be replaced with a new one.

Yes — condensed aerosol fire suppression technology as used in FireKavach is designed to be safe for use around electrical panels and equipment. The aerosol particles are non-conductive, and this class of technology is used internationally for protecting electrical and electronic enclosures specifically because of this compatibility.

Yes — that is the primary purpose of automatic fire suppression like FireKavach. It activates based on internal panel temperature reaching approximately 170°C, which typically occurs before smoke, smell, or visible flame becomes apparent from outside an enclosed panel.

This early intervention is what differentiates automatic suppression from relying on human detection — particularly relevant for unattended panels in homes overnight, closed shops, remote solar sites, and unmanned electrical rooms.

FireKavach units are designed for long shelf life as sealed, passive devices with no batteries or perishable electronic components to degrade. Specific shelf life and expiry information is provided with each unit's documentation.

As with any fire safety device, units should be checked periodically as part of routine panel inspection to confirm they remain within their service life and are undamaged.

Once a FireKavach unit reaches the end of its service life, or once it has activated to suppress a fire, it should be replaced with a new unit. Expired or activated units no longer provide reliable protection and should not be left in place as a substitute for an active device.

Replacement is straightforward — the same DIN rail mounting used for installation allows the old unit to be removed and a new one fitted in its place.

FireKavach's condensed aerosol technology differs from powder-based (ABC/dry chemical) extinguishers in particle size and discharge mechanism. Aerosol particles are extremely fine and remain suspended in the air within the enclosure, interrupting the chemical chain reaction of combustion.

Powder extinguishers rely on larger particles settling onto the fire and smothering it, which is effective for many fire types but typically leaves more residue and is designed for manual, directed application rather than automatic activation inside a sealed enclosure.
