The invention relates to an explosion-protected housing for means for transmitting and/or receiving electromagnetic radiation (). The housing comprises a housing body () that is configured to receive such transmission and/or reception means () and a window element () having a first side () that faces the housing interior and an opposite second side () that faces away from the housing interior, wherein the window element () transmits electromagnetic radiation. The housing body () has a flanging () on the second side () of the window element (), said flanging pressing the window element () in the direction of a seat () that is formed in the interior of the housing such that the housing is formed as a pressure-resistant housing and/or as a dust-tight housing.

Explosion-protected housing for means for transmitting and receiving electromagnetic radiation

A modular multi-sensor fire detector () that has an evaluation unit and a plurality of sensor heads () which are arranged locally at a distance from the evaluation unit and are connected to the evaluation unit in a signal-conducting manner, wherein the evaluation unit () can be connected in a signal-conducting manner to an alarm signal receiving device () which is locally at a distance.

Modular multi-sensor fire- and/or spark detector

The invention relates to a hazard detector for an evaluation unit (), e.g. a fire detector and/or extinguishing control center (). The hazard detector () comprises a housing () having at least one sensor unit () or a sensor interface for connecting the sensor unit () to capture a hazard parameter. Moreover, the hazard detector () comprises a first electronic assembly (), electrically connected to the sensor unit () or the sensor interface, for processing sensor signals of the sensor unit (), and a second electronic assembly (), connected to at least one first interface () for electrically connecting the second electrical assembly () to a physically remote evaluation unit (). In this arrangement, the first electronic assembly () and the second electronic assembly () comprise a wireless data connection () for transmitting the processed sensor signals from at least the first electronic assembly () to the second electronic assembly (). At least the first electronic assembly () and the second electronic assembly () are arranged inside the housing (). Further, the invention relates to a method for transmitting hazard signals and to a system having the hazard detector ().
