Asenware AW-CSH831EX-4W 4-Wire Exproof Conventional Smoke and Heat Combined Detector

The AW-CSH831EX-4W is a conventional smoke and heat combined detector housed in an exproof enclosure for use in explosive atmospheres. Because it incorporates two detection principles in a single housing, it produces an alert to the conventional fire alarm panel against both slowly developing smoky fires and events where temperature rises rapidly. Asenware positions this variant in its Ex-certified product family and specifies compliance with GB3836 and GB12476 series explosive atmosphere standards; the manufacturer's page for this code does not contain EN 54 or CPR declarations. Since wiring layout, sensitivity range, and heat alarm threshold values are not published in the product's own documentation, ASPEK requests a current code-specific datasheet from Asenware when designing with this item. Since the AW-CSH831EX without the -4W suffix appears as a separate product in the catalog, writing the code in full with its suffix in quotations and project correspondence prevents confusion.
