Publication number: 20240077341Abstract: 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.Type: ApplicationFiled: October 6, 2023Publication date: March 7, 2024Inventors: Bernd ZIEMS, Hauke DITTMER, Dirk SIEMER, Axel GROTHOFF, Peter ZÜLZER, Ame STAMER, Pawel WISNIEWSKI, Timo ZIEGENBEIN

Patent number: 11804117Abstract: The present invention relates to a subscriber, in particular a module or device for monitoring a function and/or status and/or for transmitting an alarm, having: a first interface for communicating with a control panel, preferably a fire alarm and/or extinguishing control panel, a data memory for storing configuration data relating to the subscriber comprising at least an identifier of the subscriber for identifying the subscriber with respect to the control panel, a second interface for inputting configuration data to the data memory. The second interface has an NFC interface for communicating with a mobile write and/or read device The NFC interface is configured to receive at least the identifier of the subscriber from the mobile write and/or read device and to transmit it to the data memory. The invention improves known subscribers to the effect that a configuration which is less susceptible to faults and is simpler at the same time is possible.Type: GrantFiled: January 25, 2019Date of Patent: October 31, 2023Assignee: Minimax GmbHInventors: Axel Grothoff, Thorsten Mitzlaff

Patent number: 10726707Abstract: The invention relates to a hazard detector for an evaluation unit (12, 14), e.g. a fire detector and/or extinguishing control center (12). The hazard detector (10) comprises a housing (16) having at least one sensor unit (22) or a sensor interface for connecting the sensor unit (22) to capture a hazard parameter. Moreover, the hazard detector (10) comprises a first electronic assembly (26), electrically connected to the sensor unit (22) or the sensor interface, for processing sensor signals of the sensor unit (22), and a second electronic assembly (30), connected to at least one first interface (38) for electrically connecting the second electrical assembly (30) to a physically remote evaluation unit (12, 14). In this arrangement, the first electronic assembly (26) and the second electronic assembly (30) comprise a wireless data connection (32) for transmitting the processed sensor signals from at least the first electronic assembly (26) to the second electronic assembly (30).Type: GrantFiled: April 10, 2017Date of Patent: July 28, 2020Assignee: Minimax GmbH & Co. KGInventors: Bernd Ziems, Hauke Dittmer, Dirk Siemer, Axel Grothoff, Peter Zuelzer, Arne Stamer, Pawel Wisniewski, Bernd Hallwass-Fedder

Patent number: 8400314Abstract: 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.Type: GrantFiled: May 12, 2010Date of Patent: March 19, 2013Assignee: Minimax GmbH & Co.
