Gas alarm CO2 light, CO2 light for monitoring air quality SCHOOL

Performance features Simple installation without an electrician, wall mounting optical display, from 1000ppm yellow, from 2000ppm red-adjusted electronics for interference-free instruction detection of carbon dioxide (CO2) from used internal infrared sensor 3000ppm (+ / - 0.01% vol.) automatic shutdown of the LEDs at darkness = energy-saving standard color RAL 6024 traffic green optional available in the colors white (RAL 9016) and grey (RAL 7032) of the possible use of seminar rooms, classrooms, hearing rooms, hearing rooms, regularly in the auditory rooms, and in the regular room of children. Typically, the classroom, auditorium, meeting rooms, but also production sites, large-scale offices and general event rooms, and all indoor spaces are already considered as very bad air, the maximum concentration of the MAK in Germany is 5000 ppm, the CO2-light SCHOOL, with its yellow light, is already 1000 ppm, according to a recommendation of the RKI for extensive train ventilation of the room. Those who have to breathe in a long-term poor and used air, are tired and are clearly lost in their capacity and concentration. This is particularly negative in learning and working. The immune system is also weakened, or, in the case of fresh air, it is significantly strengthened and stabilized, which may even be seen in the days of the disease over the year. This is where the CO2 light starts. Not only does it warn at strongly increased harmful concentrations, but rather it educates to air in time, even before the highest warning level becomes active. Technical data voltage: 12 V DC from the supplied power supply line: approx. 80 cm / approx. 150 cmProtection type: IP 20Sensor type: NDIR infrared, internal trigger concentrations: approx. 1000 ppm yellow / 2000 ppm red highest trigger concentration CO2: approx. 2000 ppm sensor measuring range: 400 - 3000 / 5000 ppm (+ / - 100 ppm / 5%) functional range sensor: + 5 degrees C / + 45 degrees Cair humidity (environment): 5-90% RH (non-condensing) light source: long-life LEDs with automatic night-shift dimensions (HxDxT): 303 x 55 x 80 mm supply-wide CO2-light with 0.8 m supply line and wall-mounting-set-power supply unit with 1.5 m supply line and hollow-line control line: A number of questions can be found in the air: In classrooms a light is enough, a standard gym should be equipped with 2 lights and a Pax400 Aula may be equipped with 3 or 4 lights. This is also related to space geometry and cannot be expressed in square meters in a flat-rate way. The device remains in continuous operation for 24h or is it to be switched on for every room use? The light and the attached power supply are suitable for both options. It is a light sensor installed in the light, which switches the LEDs off after 10 minutes of darkness and immediately on again at brightness, so it is automatically saved at night when the space is not used. How long does it take to switch on until it is ready for use? 180 seconds all initialization processes and self-tests are completed and the first meaningful evaluation takes place with an immediately displayed result. During this start phase, the lowest level flashes green. In the instructions says test after 5 years. How does this work? Basically, you can check the sensor yourself. Just take a deep breath and blow gently with spitten lips towards the protective grid. The CO2 value of your breathing air is very high with a few 10,000 ppm, the fast increase for normal room air is absolutely untypical. The traffic light notices this and reacts with a direct jump to the red warning level. This means that the basic function of the sensor is tested. You can also send us the light for a free work test, where we may adjust the sensor. If we need to exchange the sensor, you will receive a reduced exchange offer, as with all other gas detectors from our house. Regular or daily train ventilation also helps the traffic light to a higher and longer reliability. 5 years are a good point of reference, we assume that the sensor will last much longer. But as usual with sensor technology, this will never be guaranteed. On which side and at what height should the light be mounted? Especially in class rooms for which this light version is optimized, the assembly in the field of vision of the teacher, but outside the area of view of the students, is recommended to not unnecessarily distract it. In the classic frontal class, therefore, at the back wall at medium or slightly increased room height, in the middle between windows and doors. Exhaust CO2 is at first slightly heated by the body temperature and is distributed quite homogenously in the room, just when several people are in one room. In the case of generally bad air, you will hardly find a place in the room where there is only good air. Therefore, the position finding for the traffic light should not be overrated. Of course, it is necessary to cut off from the installation directly next to a permanent tipped window.
