GS 2.1 61185 Gaswarngerät GS 2.1 Methan Application example Propane Images 5 Back gas alarm unit GS 2.1 Methane | 61185 gas alarm unit GS 2.1 in-stock items Downloads Benefits for private homesDetection of, for example, natural gas (methane) and liquefied gas (propane, butane) in ambient air and generation of gas alarmwith relay for external sensor Application For the detection of flammable gases such as methane, propane, butane in ambient air in residential buildings. Description Gas alarm unit with integrated semiconductor sensor, alarm buzzer and relay output for connection of additional external alarm equipment (e.g. horn, warning light). LEDs for operation (green), alarm (red), error (yellow), the Test key and the Reset button are located at the front side of the housing. The alarm is triggered when approx. 20 % of the LEL (lower explosive limit) is reached. The audible alarm can be muted with the Reset button. The visual alarm remains active until the alarm condition no longer exists. The unit features an additional input for connection of an external gas sensor GS 4 as a second measuring point, e.g. for monitoring different rooms.
