A fire warning device comprises detachably connectable shell parts (1, 2) which when brought together are mutually united to form a shell or casing (3) which houses a fire sensor (20), alarm emitter (21) and a power source (22), said shell (3) being provided with fire warning device suspension means (8, 9; 16, 17). The suspension means (8, 9; 16, 17) is comprised of a friction anchoring device disposed in the region of the border surface or interface (6) between the two shell parts (1, 2) when the shell is closed. The friction anchoring device si disposed in a passageway that extends between two mutually opposite ends (4, 5) of the closed shell and enables said shell to be closed around a rod, cable or chain that carries a light fitting, whilst connecting the cable, rod or chain to said friction anchoring device for suspending the fire warning device. |
