The Hochiki DCD-1E-IS(WHT) is an intrinsically safe conventional rate of rise heat detector with a 60 °C fixed temperature element, in a white case. It is designed for hazardous areas such as refineries, chemical plants and fuel stations, and has a remote indicator output.
Like all intrinsically safe equipment, it must be connected through a Zener barrier or galvanic isolator (such as the Hochiki Z787) to limit the energy entering the hazardous area. Hochiki allows up to 20 intrinsically safe detectors per zone.
