Catalog excerpts

Building technology Smoke sensor Semiconductor gas sensor in plastic housing for connection to gas and smoke detector GRM. For use in dry rooms (e.g. heating installations). Detectable media: methane, propane, butane. LEDs at the sensor indicate the operating and alarm state of the gas alarm system: Photoelectronic smoke sensor in plastic housing for connection to gas and smoke detector GRM. For use primarily in residential buildings (living rooms, bedrooms, halls, staircases, corridors, etc.). The operating and alarm state is indicated at the sensor: Operation Fault Gas alarm Visual: LED red/red Audible: Internal piezo buzzer When ordering, please specify the gas to be monitored since the sensors must be calibrated for the desired gas. Technical specifications Measured gases Inflammable gases and vapours in ambient air. Gas sensors are cross-sensitive to hydrocarbons, lacquers, solvents, alcohols, etc.). Measuring range 0–50 % LEL Measuring principle Semiconductor (service life approx. 5 years, depending on the operating conditions) Operating temperature range Ambient: 0/40 °C Humidity Max. 75 % rH Housing Wall mounting plastic housing W x H x D: 80 x 80 x 35 mm Weight: Approx. 100 g Sensor Photoelectronic Measuring principle Scattered light principle Alarm tone 85 dB(A) (at a distance of 3 m) Test button For sensitivity, audible alarm Operating temperature range Ambient: 5/39 °C Humidity Max. 80 % rH Housing Wall mounting plastic housing Outside dimensions (Ø x H): 155 x 38 mm Weight: Approx. 195 g Electrical connections Screw terminal strip i Gas sensor calibration Prior to shipment, the gas sensors are calibrated to the gas specified by the customer. Therefore, please always indicate the gas type when ordering. Please order sensors and calibration separately. Gas sensor for propane, butane Smoke sensor
