Gas detection according to DIN EN 50194-2 and DIN EN 50291-2 (CO version). Permanent temperature compensation. Regular self-test to determine functionality. Internal siren 94 dB. Auto Sense input and alcohol filter. Push button for "pause" and "ON/OFF". LED indicator for both sensors.

The G.A.S-pro III is available in two basic setups:

1. With integrated liquid gas or narcotic gas sensor

2. With integrated CO sensor (part number 80256)

Both versions can be combined with another gas or CO sensor. Thanks to technical progress, the current consumption drops to a minimum of 26 mA in combination with a liquid gas/KO gas sensor, and to just nine milliamperes in combination with a CO gas sensor. The internal siren increases to a piercing 94 dB, and an integrated humidity sensor optimizes measurement when there is high humidity in the vehicle or when breathing air is in close proximity to the sensor. An alcohol filter prevents false alarms caused by alcohol in the air.Thanks to an integrated radio unit, the new G.A.S-pro III does not need to be connected to the control panel but only to the on-board power supply.
