DSC-EA | Hochiki's UL Approved Fire Detection

DSC-EA Description 

 

DSC-EA, the rate of rise heat detector is suitable for use in most applications that require heat detection. Please note that special attention should be given to avoid installation in direct line with hot air heaters, above stoves, ovens, or other heat-generating objects.

 

The DSC-EA rate of rise heat detector is composed of an air chamber, vent, and a flexible metal diaphragm. When the DSC-EA is heated, the air in the chamber expands. The vent permits the chamber to breathe and slowly release the expanded air. If a fire occurs, the air in the chamber will expand more rapidly than it can be vented. This causes the diagram to close a set of precious metal contacts (normally open) to trigger the alarm signal.
