Abstract: The optical detector of a value of an atmospheric physical quantity representative of a danger includes: a measurement chamber accessible to the atmosphere; an electronics compartment for receiving electronics for detecting the value of the atmospheric physical quantity representative of a danger, the detecting electronics including electronic elements comprising at least: a light emitter, a light receiver that is sensitive to at least some of the wavelengths of the light rays emitted by the emitter, and electronics for processing detection signals, the detector in addition including: a first light guide facing the emitter in order to direct the light emitted by the emitter from the electronics compartment to a detecting zone in the measurement chamber; and a second light guide facing the receiver in order to direct light originating from said detecting zone to the electronics compartment in order to be received by the receiver, the amount of light received by the receiver being representative of the

Abstract: The optical scattering-based smoke detector comprises a scattering zone accessible to the smoke, a printed circuit forming a supporting member and a first and second light reflectors mounted on a common supporting member. An electronic smoke detection unit, a light emitter and a light receiver are mounted on the printed circuit. The receiver is sensitive to at least some of the wavelengths of the light rays emitted by the emitter. The first light reflector facing the emitter to direct the emitted light into a detection zone in the scattering zone. The second light reflector facing the receiver to direct, in the presence of smoke in the scattering zone, the scattered light from the detection zone onto the receiver. A single mechanical part comprises the first and second light reflectors and a link resistant to the passage of the light from the first light reflector to the second light reflector.

Abstract: An extinguisher identifying device. The device comprises an extinguisher identifying device and an activation device, and a communications module. The extinguisher identifying device reads an identifying element on an extinguisher to obtain identifying data of the extinguisher. The activation device is configured to activate the extinguisher identifying device in response to a predetermined event. The communications module is configured to transmit the extinguisher identifying data to a management device.
