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 ().

Hazard detector and method for transmitting a hazard signal and system comprising the hazard detector

A fire alarm consists of a housing in which sensors, a radiation source, and an optical window are disposed. A reflector protection basket or ring is disposed above the optical window. The basket or ring is suitable for protecting the optical window against mechanical influences, allows UV and IR radiation to pass through to a sufficient degree, and reflects UV and IR radiation from the housing interior, on its inside. Monitoring of the contamination of the window, function monitoring of the sensors and of the signal processing electronics, as well as easy replaceability of the components in the fire alarm are provided.
