Abstract

A recessed smoke and/or heat detector (1) for mounting in a ceiling panel (7) is disclosed. The disclosed detector comprises a detection sensor that is mounted within a housing (2), the housing being configured to be pushed through a hole cut in a ceiling panel to project into a ceiling void above. The housing is open at its lower end (3) to allow smoke and/or heat from a room below to reach the detection sensor in use. The recessed detector comprises a reflector that extends from the lower end of the housing towards an upper end (4), the reflector having an internal, light-reflecting surface (17) that converges from an open, lower end (16) towards a top of the reflector (19). The detection sensor and a light source (22), which is configured to produce emergency lighting to the room below, are positioned within a space defined by the internal surface of the reflector. An audible alarm device for emitting an alarm warning sound in the event that a fire is detected may also be positioned within the reflector.
