SM87PB, SM87BG устройство включения сигнализации взрывозащищенное
Product description
Ex d, Intrinsically Safe (Ex ia), Weatherproof
These manual fire alarm, emergency shutdown break-glass and pushbutton units have been designed for the most arduous environmental conditions. The units are both easy to install and maintain. Intrinsically safe Ex ia and flameproof Ex d versions of each model are available. A choice of either stainless steel or alloy makes the range suitable for either the offshore or onshore industries. Stainless steel, one of the most durable materials available on the market, is both hard wearing and corrosion resistant, increasing the life of products in harsh environments and therefore reducing maintenance costs. Stainless steel, one of the most durable materials available on the market, is both hard wearing and corrosion resistant, increasing the life of products in harsh environments and therefore reducing maintenance costs.
Both the Exia units and the Exd units have the same external appearance. Also the internal components are identical throughout the range. Each unit can be wired for either NO, NC or CO contacts to customer specification (Fig.1)
Описание
SM87PB, SM87BG устройство включения сигнализации взрывозащищенное
Ручная пожарная сигнализация, аварийное отключение разбитым стеклом и кнопка блоки были разработаны для самых тяжелых условий окружающей среды.
Устройства просты в установке и обслуживании. Искробезопасность Ex ia и взрывонепроницаемые версии Ex d для каждой модели.
Выбор из нержавеющей стали или сплава делает диапазон подходящим для любоой оффшорной или оншорной промышленности. Нержавеющая сталь, один из самых прочных материалов, доступных на рынке, является износостойким и устойчивым к коррозии, что увеличивает срок службы изделий в суровых условиях и, следовательно, снижение затрат на техническое обслуживание.
И блоки Exia, и блоки Exd имеют одинаковый внешний вид. Также внутренние компоненты идентичны во всем диапазоне. Каждый блок может быть подключен к NO, NC или контактам СО по спецификации заказчика (Рис.1)
