The MagicSafe MSG 150 gas detector detects the presence of narcotic gases in the atmosphere and immediately triggers the alarm: the integrated buzzer emits an audible signal and the red LED flashes. Simultaneously, the output relay is switched on. It can be used to activate external alarm units up to 10 A. You can silence the audible alarm by pressing a button. The same button can be used to start the sensor’s function test. Any system failure will be immediately indicated. The sensor detects narcotic gases based on ether, chloroform, butane, ethane and trichlorethene. It automatically adjusts to the room atmosphere.
