The MAGIC SAFE MSG 150 gas detector detects anaesthetic gases in the room air in time and report it immediately: the integrated buzzer gives an audible signal while the LED light lights up red. At the same time, the output relay is switched on. It is used to activate an external alarm system with up to 10 A. The acoustic alarm can be switched off by pressing a button. The same button also serves to initiate the sensor function tests. Any system errors are displayed immediately. The sensor detects anaesthetic gases, the ether, chloroform, butane, Ethan and Trichlorethen-based. It adjusts itself automatically to the temperature of the atmosphere.
