Abstract
A smoke detection unit has two identical smoke detectors juxtaposed horizontally, each made up of at least one smoke sensor positioned beneath and coupled to a measuring chamber fitted with walls. The detectors are encapsulated in a rigid cavity having an upper base and a lower cover positioned opposite the smoke sensors. A base is formed by the walls of each of the two measuring chambers. A method further fixes the smoke detection unit to a bearing structure.

A smoke detection unit, comprising:
- two identical smoke detectors juxtaposed horizontally and each having a measuring chamber with walls and at least one smoke sensor positioned beneath and coupled to said measuring chamber;
- and
- a rigid cavity encapsulating said smoke detectors, said rigid cavity having an upper base and a lower cover positioned opposite said smoke sensors, said upper base is formed by said walls of said measuring chambers of said two identical smoke detectors.
A method for fixing a smoke detection unit, which comprises the steps of:
- providing a smoke detection unit containing two identical smoke detectors juxtaposed horizontally and each having a measuring chamber with walls and at least one smoke sensor positioned beneath and coupled to the measuring chamber and a rigid cavity encapsulating the smoke detectors, the rigid cavity having an upper base and a lower cover positioned opposite the smoke sensors, the upper base formed by the walls of the measuring chambers of the two identical smoke detectors;
- and
- fixing the smoke detection unit to a bearing structure by rigidly connecting parts on a circumference of the lower cover onto at least one corresponding edge of the bearing structure.
