Domestic gas detector H400-CO

Domestic gas detector H-400-CO is designed to monitor the level of carbon monoxide and signal light and sound at excess levels.
Carbon monoxide is a highly toxic gas, causing heavy damage even when inhaled in very small quantities. It is colorless and odorless, making it undetectable by human senses. Carbon monoxide is released during incomplete combustion of substances. Common sources of CO are smoke, heaters, fossil fuel furnaces and car exhaust.
Domestic gas detectors H-4000-CO has been designed to simulate the behavior of the human body by inhalation of carbon monoxide. During normal operation, it measures the concentration of CO per second. When the gas concentration exceeds 40 ppm began reporting on the response time of the device. The reaction time varies depending on the concentration of CO – the higher concentration the faster turns the light and sound signals.
The response time is according to EN 50291
LED: green LED – normal operation, red – alarm, yellow – failure. The first time the sensor prepares 30s. Device gives a double beep sound and lights green LED /normal operation/. Domestic gas detector H-400-CO has a TEST mode, which can be checked saws without the alarm and function – self-diagnosis to check the status of the sensor.
