KILLARK XAL-53 — explosion-proof fire alarm pull station for hazardous locations.
The XAL-53 suits areas with flammable gases or vapors, combustible dusts, or easily ignitable fibers or flyings, such as petroleum refineries, chemical and petrochemical plants, storage areas and other facilities where hazardous substances are handled and stored. It is activated by lifting the front cover and pulling down the ring; this two-step action prevents unintentional operation. It is reset by depressing the shaft and returning the plate to its original position.
