Kidde Fenwal 85-100000-100 — Control Head Monitor with explosion proof assembly, a supervisory switch reporting the position of a control head on a suppression discharge valve.
It is fitted between the discharge valve and an electric or electric/cable operated control head, so an existing system gains supervision without either part being replaced, and the explosion proof housing serves normal and classified areas alike.
