Fire is a calamity that strikes without any warning and causes an unimaginable havoc. According to a survey conducted, 80% of the most damaging fires occur during night times, weekends or holidays when no one is around. Hence an automatic operation is the only solution for round-the-clock protection against any kind of fire. Fire Stone fire extinguishers are simple and economical solution for buildings or structures where detection and suppression piped systems prove cumbersome and very expensive.

How Do They Work?

When heat from an uncontrolled fire increases to a pre-set temperature of the unit, the fusible link releases, discharging the extinguishing agent. The release temperature of the extinguisher (fusible link) can be pre-set at works ranging from 57 deg C/68 deg C/79 deg C/93 deg C/140 deg C and so on. They require no external source of energy and it can be operated electrically manually or mechanically for their operation.
