The Edwards E-PDD comes designed for easy installation and also represents the perfect balance of practical design and advanced technology.
The Edwards E-PDD features a unique design that speeds installation and simplifies maintenance. Furthermore, removable dust filters, conformally coated circuit boards, and optional water-resistant gaskets keep contaminants away from components, ensuring years of trouble-free service. When cleaning is required, the assemblies come apart easily and snap back together in seconds
The duct smoke detector’s primary purpose is to provide early warning of an impending fire and shut down the HVAC unit in order to prevent smoke from circulating throughout the building. Also, the duct smoke detector designed for use in duct applications where temperatures can exceed standard detector capabilities.
The Edwards E-PDD duct detector is ideally suite for duct smoke detection applications where an early indication of combustion is require within the confined space of ventilation ductwork. Its primary purpose is to provide early warning of an impending fire and to prevent smoke from circulating throughout the building. It is typically use to detect smoke in the supply side of the HVAC system but can provide supervision of the return side as well.
