CA 2510752

A detector assembly (10) powered by mains electricity and an elongate backup battery (76) is disclosed. The assembly includes: a ceiling mountable base (10) having a body defining a downwardly opening socket (24); a detector module (20) having a battery support portion (75) for holding the battery (76) in a vertical orientation, the module (20) receivable by the socket (24); a quick connection means for mechanically and electrically connecting the module (20) to the base (10); and shutter (50) mounted to the base (10). The shutter (50) prevents operation of the quick connection means when no vertical battery (76) is installed within the module (20). The quick connection means comprises co-operable pairs of conductors. The conductor pairs transmit power from the base (10) to the module (20). The pairs of conductors each comprise a stud conductor mounted to the base (10) and a forked conductor mounted to the module (20).

L'invention concerne un dispositif de détection (10) à alimentation électrique et à batterie auxiliaire (76) allongée. Ledit dispositif comporte une base (10) montée au plafond ayant un corps définissant une douille (24) s'ouvrant vers le bas ; un module (20) détecteur ayant une partie support (75) de batterie destinée à retenir la batterie (76) verticalement, ledit module (20) pouvant être logé dans la douille (24) ; un moyen de connexion rapide permettant de connecter mécaniquement et électriquement ledit module (20) à la base (10) ; et un obturateur (50) monté sur la base (10). Ledit obturateur (50) empêche le fonctionnement du moyen de connexion rapide lorsqu'aucune batterie (76) verticale n'est installée dans le module (20). Le moyen de connexion rapide comprend des paires de conducteurs coopérants. Ces paires de conducteurs transmettent le courant électrique de la base (10) au module (20). Elles comprennent chacune un conducteur goujon monté sur la base (10) et un conducteur à fourche monté sur le module (20).
