Electrical cabinet miniature automatic fire extinguishers and clean-agent or CO2 automatic suppression systems provide fast, automatic fire protection inside vending machines by detecting heat through heat-sensitive bulbs or tubing. Once detected, they will extinguish electrical fires without water or damage to sensitive components.
Correct positioning of an automatic fire extinguisher inside a vending machine is essential to ensure it activates quickly and suppresses a fire at its source. The fire extinguisher should be installed in the areas where fires are most likely to start, particularly inside or directly above the electrical control panel, which houses power supplies, control boards, relays, and high-current wiring. This is the highest-risk zone, as most vending machine fires originate from electrical faults or overheating components.
For machines with refrigeration systems, an additional extinguisher should be positioned in the compressor compartment, ideally mounted above the compressor to allow the suppression agent to disperse freely without being obstructed.
