LOT OF 4
The Tyco 4B-DHM is a deckhead mounting base used in a ship’s fire alarm system. As its name states, it is a base intended for installation on the deckhead, the overhead surface of a compartment, where it forms part of the fixed fire alarm hardware. The base carries the marking 398/02 alongside the model designation 4B-DHM. It belongs to the physical installation side of the fire alarm plant rather than its control equipment. The base is in used condition.
