Carbon monoxide / carbon monoxide and gas sensor (propane, butane, LPG) GV-9 with LCD display Compliance with the PN-EN 50291-1: 2010 standard KING sensor, model GV-9 Sensor lifetime 5 years Voice prompts. Instruction in Polish. A modern, technologically advanced sensor of carbon monoxide and gas. High sensitivity thanks to a modern electrochemical sensor. The LCD panel displays the gas / carbon monoxide level in the range from 0 to 999PPM, low battery and failure. Exceeding the level of carbon monoxide / gas is signaled by LED diodes and a voice command about threat detection. Two power sources: 1. power supply from a 230v socket via a cable. 2. emergency 9v rechargeable battery (do not use ordinary 9v batteries) After detecting carbon monoxide / gas, the sensor activates the alarm siren and visual and audible signaling. Remember that the sensor detects a threat where it is installed, therefore, for safety reasons, we recommend installing it not only in the bedroom, but also in the corridor, etc. ). The device is inexpensive and can save your life. CERTIFICATES: CE, ROHS When a threat is detected, the detector triggers a very loud alarm (85dB). Additionally, the red LED lights up and voice commands are given. The alarm is turned off by pressing the "Push to Test" button. The "Push to Test" button is also used to check the correct operation of the sensor. The condition of the sensor, battery and internal circuits is constantly monitored. The sensor has been tested in a specialized gas laboratory based on the PN-EN 50291-1: 2010 standard Test results are positive for all PPM levels: 30ppm, 50ppm, 100ppm and 300ppm The condition of the sensor, battery and internal circuits is constantly monitored.
