These units are suspended from the ceiling and automatically activate when exposed to extreme heat caused by a fire. We stock automatic extinguishers available in powder or clean agent variants.

Automatic Fire Extinguisher FAQs

How does a ceiling mounted automatic extinguisher work? Open

Most automatic extinguishers are fitted with a heat-sensitive bulb. When the temperature rises to its rated activation point (usually between 68°C and 93°C), the bulb bursts and releases the extinguishing agent to suppress the fire.

Do ceiling mounted automatic extinguishers need a power supply? Open

No, ceiling mounted automatic extinguishers are completely self-contained and require no external power source. They activate mechanically using a heat-sensitive bulb (Quartz Bulb Detector) that bursts at a set temperature, releasing the extinguishing agent automatically.

Should I use dry powder or clean agent? Open

Dry powder extinguishers are versatile and suitable for most fire types, making them ideal for storage areas, garages, and plant rooms. Clean agent models are better for areas with sensitive electronics or where a residue-free discharge is preferred, like server rooms or control panels.
