Antec SKH089 MO-1/MO-2 Flame Sensor With Automatic Fire Extinguishing Function
Manufacturer: Antec Co. Ltd.
Model: SKH089 MO-1/MO-2
Features
The system detects fires caused by electromagnetic switches (magnets) on switchboards, a leading cause of electrical fires in factories. Upon detecting a fire, it quickly sprays CO₂ gas to suppress it, protecting equipment and simplifying recovery. The sensor and fire extinguishing device are easily installed on a DIN rail. It supports AC85-240V and DC24V power supplies, with the SKH089MO-2 compatible with AC power. The high-capacity 2c relay cuts off the power line to prevent fire spread.
