HOCHIKI DSC-EA Rate of Rise Heat Detector

HOCHIKI DSC-EA Rate of Rise Heat Detector

The DSC 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.

 

1. The DSC features a slim design which combines visual appeal with a high standard of reliability. 2. The design of the DSC enables the detector to operate in locations where the temperature is likely to increase suddenly should a fire develop. 3. The operating characteristics of DSC is a key feature of the product enabling a very cost effective solution for the use of heat detectors. This detector consumes no current in standby, which enables an unlimited number of detectors to be connected on the same detection wires. 4. With connection to the standard Hochiki range of conventional bases, the DSC heat detector can be connected or disconnected very easily, allowing simple interchangeability with other members of the Hochiki conventional detectors.

Product Description

The DSC rate of rise heat detectors are composed of an air chamber, vent and a flexible metal diaphragm. When the DSC 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 (nornally open) to trigger the alarm signal.

 

Rated Voltage: 24VDC Working Voltage: 15 – 30VDC Maximum Switching Current: 100mA max. Heat Sensing Element: Air chamber composed with the diaphragm. Operating Temp.
