A fire warming 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.

L'invention concerne une alarme-incendie comprenant des éléments coque (1, 2) pouvant être reliés de façon amovible. Assemblés, ces éléments coque forment une coque ou un boîtier (3) qui abrite un détecteur d'incendie (20), un émetteur alarme (21) et une source de courant (22). Cette coque (3) est dotée d'un moyen de suspension (8, 9; 16, 17) destiné à l'alarme-incendie. Le moyen de suspension (8, 9; 16, 17) est constitué d'un dispositif d'ancrage par friction placé dans la zone de la surface limite ou interface (6) entre des deux éléments coque (1, 2) quand la coque est fermée. Le dispositif d'ancrage à friction est placé dans un passage qui s'étend entre deux extrémités opposées (4, 5) de la coque fermée de telle façon que la coque puisse être fermée autour d'une barre, d'un câble ou d'une chaîne qui porte une garniture d'éclairage et le câble, la barre ou la chaîne sont connectés à ce dispositif d'ancrage à friction aux fins de suspension de l'alarme-incendie.
