Presence detector G491Komfort

Product name: Presence detector Komfort Design: Surface-mounted Item no.: 0304 0x ETS search path: Gira Giersiepen, Phys. sensors, movement detectors, presence detector komfort Functional description: The presence detector KomforT is used for the detection of presence (presence detector mode), for the detection of movements (ceiling-mounted detector mode) and for the supervision of signalling telegrams (signalling mode) in rooms. In these three modes of operation, the device offers 4 output channels, two of which can be active in one mode of operation respectively and which can be independently parameterized. The modes of operation presence detector, ceiling-mounted detector and signalling mode can be defined when the device is parameterized with the ETS software. The detector is provided with an alarm function which is activated when the device is removed from the bus coupler. The presence detector Komfort can be used as a stand-alone unit, as master (main unit) or slave unit (extension unit) and should be mounted exclusively under the room ceiling from where it monitors the area below. The detector is equipped with a passive infrared sensor (PIR) and responds to thermal movements triggered by persons, animals or objects. To extend the detection range, several presence detectors can be used in the same room by combining a device parameterized as master with several other devices parameterized as slaves. It it also possible to connect the presence detector Komfort to a flush-mounted Komfort detector parameterized as a slave unit or with the flush-mounted Standard detector in an extension application. The purpose of a presence detector is to switch on the light depending on brightness when a movement is detected, and to switch it off when it is no longer needed. This is the case when there is sufficient brightness without any additional artificial light, and when nobody is present anymore. This means that the presence of a person is detected depending on a preset brightness
