DC Manual Call Point with EXd Classification

The DC Manual Call Point Ex functions to act together with Fire Detection and Alarm Systems (SDAI) in EX-type classified areas.

The Ex d protection ensures the ability to install in various indoor and outdoor environments that contemplate this level of classification. The constructive measures in the enclosure prevent the propagation of an explosion from inside the electrical instrument to the surrounding explosive atmosphere.

The mobility of being a wireless device also ensures the ability to relocate in the simplest and fastest way possible, even being performed hot, that is, with the equipment in operation.

Ex devices, or explosion-proof, are components specially designed to operate safely in environments with potentially explosive atmospheres, such as petrochemical industries, refineries, and flammable product storage areas. These devices are manufactured to prevent any spark, heat, or electrical discharge generated internally from causing an ignition in the surrounding environment.
