Danger Detector With A Non-Contact Heat Radiation Sensor For Establishing An Ambient Temperature

摘要

A danger detector configured as a point detector includes an alarm housing with an alarm cover, a non-contact heat radiation sensor that is sensitive to heat radiation in the infrared range, and a treatment unit configured to determine and emit a temperature value derived from the detected heat radiation for the ambient temperature in the surroundings of the danger detector and/or an alarm, in the event that the currently determined temperature value exceeds a predetermined temperature comparison value. The heat radiation sensor is arranged in the alarm housing and is configured to optically detect the ambient temperature on the inner side of the alarm cover. The heat radiation sensor may be a thermopile designed as an SMD component.

1. A danger detector embodied as a point-type detector, the danger detector comprising:
an alarm housing with an alarm cover, a non-contact heat radiation sensor configured to generate a sensor signal corresponding to heat radiation in the infrared range, a processing unit, and computer instructions stored in non-transitory memory and executable by the processing unit to:
determine an ambient temperature value for an ambient temperature in an environment of the danger detector based on sensor signal generated by the non-contact heat radiation sensor, andbased on the determined ambient temperature value, output at least one of:
the determined ambient temperature value, oran alarm message in response to the determined temperature value exceeding a predetermined temperature comparison value, wherein the non-contact heat radiation sensor is disposed in the alarm housing and is aligned optically with an inner side of the alarm cover.
