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 housinghas a cylindrical outer surfacehaving smoke openingsthrough which the smoke particles enter housing, and a radially symmetric light-guiding structurewith 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 openingsby multiple reflection. Higher detection sensitivity for optically detecting smoke particles can be achieved as a result.

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.
