Publication number: 20220268681Abstract: The invention relates to a housing for a detection unit for optically detecting smoke particles. The detection unit has a light source for emitting radiation to be scattered by smoke particles to be detected and a light detector for detecting the scattered radiation. The housing 2 has a cylindrical outer surface 7 having smoke openings 8 through which the smoke particles enter housing 2, and a radially symmetric light-guiding structure 9 with guide members. The guide members are so designed that adjacent guide members each form a guide channel through which the radiation emitted from the light source and not scattered by the smoke particles is guidable to the outside in the direction of the smoke openings 8 by multiple reflection. Higher detection sensitivity for optically detecting smoke particles can be achieved as a result.Type: ApplicationFiled: July 31, 2020Publication date: August 25, 2022Inventors: Jens EICHMANN, Carl DECHAU, Thorsten MITZLAFF, Timo ZIEGENBEIN, Hauke DITTMER, Dirk SIEMER

Patent number: 8791826Abstract: A method for fire detection in enclosed environments (1) subject to explosion protection regulations out of which an air-dust mixture is filtered while the concentration of dust of the air-dust mixture is lowered to under the explosion limit by a filter (2) and the aspirated air-dust mixture is checked for burning characteristics and if appropriate a fire alarm is triggered, in which the function of the filter (2) is monitored, the fire detection is carried out by use of an aspirating smoke detector system (7) not approved for use in potentially explosive areas but instead is deployed outside the ex-zone and if the filter (2) is destroyed a signal processing unit (15, 15.1) of a malfunction monitoring sensor (14) generates a signal which initiates a subsequent action preventing aspirated air-dust mixture with an elevated concentration of dust from entering the aspirating smoke detector system (7).Type: GrantFiled: November 28, 2011Date of Patent: July 29, 2014Assignee: Minimax GmbH & Co.

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.

Patent number: 8253106Abstract: A device for detecting flames in which at least two identical detectors are disposed next to one another. Each detector has an identical signal processing circuit having an amplifier and an A/D converter, and a symmetrical and similar layout, i.e., conductor track placement. Each of the detectors covers a different wavelength range, by way of a preceding filter, and the signal detection takes place at the same time and synchronously, so that a precise analysis of the received radiation occurs using simple algorithms, independent of disruptive influence variables. By using the same detectors and the same signal processing systems, as well as the symmetrical and similar configuration of the conductor track placement, as well as the synchronous control of the signal recording, interference variables occur uniformly on all optical reception channels. This uniform interference can be compensated without complicated algorithms.Type: GrantFiled: May 12, 2010Date of Patent: August 28, 2012Assignee: Minimax GmbH & Co.

Patent number: 6788208Abstract: A method and a fire-alarm system controls stationary fire-extinguishing systems. The fire-alarm devices of the fire-alarm system are equipped with one or more detectors. If at least one pre-adjustable alarm threshold of a fire identification characteristic is reached, the fire-extinguishing device is activated and the fire detectors are selectively switched to a higher stage of sensitivity. The detectors to be switched are locally selected depending on the actual development of the fire in terms of space. The dynamic adaptation of the sensitivity of the detectors to the development of a fire permits analyzing the development of the fire through the generated smoke, water vapor or extinguishing-water mist, and to influence the fire-extinction process in a targeted manner.Type: GrantFiled: January 31, 2003Date of Patent: September 7, 2004Assignee: Minimax GmbHInventor: Hauke Dittmer
