Various sensors can be connected to the GX-A1+ universal gas warning device, but not the CO sensor tested by the TUV, because it communicates with warning devices in a different way. Therefore, we have designed the set GX-A1+CO, which enables you to equip a professional carbon monoxide warning device with an external sensor, in order to position the warning device in front of the room to be monitored, the sensor in it, in order to see from the outside whether the room has to be entered safely. The concentration of carbon monoxide is evaluated and displayed in ppm-exact, in the event of an alarm, a potential-free changeover relay and another relay switches in the event of technical faults detected by the warning device itself, such as a cable break or sensor failure, in order to inform the buildings control technology.THE GAS ALARM GX-A1-CO is a combination of ext. CO-sensor and control device for carbon monoxide and warns of CO concentrations specified in DIN EN 50291 (CO in living rooms). This monitoring system is therefore very sensitive to its purpose. This CO gas detector must only be used together with the enclosed CO sensor. An LCD display constantly informs you about the operating status. The alarm signal is audible and visual, both on the control unit and on the sensor itself At the same time, a potential-free relay is switched, for example to lock the gas supply line with a magnetic shut-off valve, so that no further gas can escape at a possible leak in the gas line or in the gas heat. Another relay switches in the event of technical faults detected by the computer itself. The device must not be used in hazardous areas. Control unit and sensor are matched. Only operate the two devices together and only in dry indoor rooms with similar usage, e.g. in living rooms, shops, shops, offices, In dusty workshops, seminar rooms and much more.As previously with the GX-A1, the special version with the TUV-tested CO sensor is also available for the new GX-A1+. On the one hand, the CO sensor requires a higher operating voltage for its own alarm, on the other hand, a ppm-exact display and equally accurate alarm is now possible. The warning levels and delay times correspond to the parameters specified in the DIN EN 50291 standard. The special advantage of the GX-A1+CO is the ability to monitor a room for harmful CO concentrations, but to leave the actual warning device out of the room to be informed of how long it can be entered before entering the room. The potential-free 230-volt change-over relay is ideal, for example, to switch on forced ventilation in the pellet bunker in case of alarm and thus to quickly reduce the high CO concentrations to a tolerable level. Gas thermal baths should also be shut down in the event of a hazard in order to prevent subsequent CO flow. A further relay for up to 60 V DC voltage informs the house automation or building control system, if necessary, of technical faults that are detected by the warning device itself.Possible applicationsCarbon monoxide CO from incomplete combustionOpen fireplace, gas thermal baths, suspended furnacesOpen fire, barbecue facilities, pellet bunkersThis text is machine translated.
