DIN-Rail Heat Aerosol Fire Extinguishing Devices
Automatic Fire Suppression for Distribution Boards
Stopping Electrical Fires at Their Source
Electrical Testing UK now supplies and installs DIN-rail mounted heat aerosol fire extinguishing devices — a compact, fully automatic solution for stopping electrical fires at their most common point of origin: inside the distribution board.
Most electrical fires begin within consumer units, control panels or distribution boards, often going undetected until significant damage is done. This device mounts directly onto standard 35mm DIN rail, sitting alongside your existing breakers, and activates automatically the moment heat reaches its trigger temperature. It then releases a fine aerosol that interrupts the chemical chain reaction of the fire, suppressing it within seconds — with no residue that damages surrounding equipment.
Key Features
Whole-Building Fire Protection
We design and install fire protection across the full scope, detection, suppression, passive measures and emergency systems, specifying each element around the specific risks, occupancy and layout of your building.
commercial and industrial Installation
We install fire protection systems for site operators and facilities teams as well as commercial, industrial and public sector clients, with every installation designed to the relevant British Standards and fully certified on completion.
Suppression System Installation
We install gaseous, water mist and other suppression systems for high-risk areas including server rooms, plant rooms, commercial kitchens and industrial environments where conventional sprinkler systems are unsuitable.
Passive Fire Protection
We install fire doors, intumescent seals, fire-rated cable management and compartmentation measures that limit the spread of fire and smoke through a building, protecting escape routes and slowing structural damage.
Ongoing Maintenance and Testing
We offer planned maintenance contracts for all fire protection systems we install, ensuring every element of your fire protection infrastructure remains compliant and fully operational throughout its service life.
Key Features
- Mounts onto standard 35mm DIN rail — installs in the board itself
