Control unit DUOline Datasheet

Control unit DUOline • Universal control unit - for explosive gases and vapours - CO measuring and ventilation control unit for indoor car parks - Oxygen control e.g. in mines, shafts, labs etc. • 2 multiplexed sensor inputs • 2 programmable threshold values • clearly arranged display • 2 colour LED green/red/orange for displaying operation/alarm/malfunction • on and off delay integrated • audible alarm • easy to install and to operate • permanent safety • attractive price • Swiss quality product Data and design subject to change without notice DUOlineUniv V080506kh Functionality The control unit DUOline is designed for connecting one or two gas sensors. Depending on the specific gravity of the gas to be detected, the gas sensors are mounted at the ceiling or 20 cm above the floor. For controlling toxic gases and oxygen, the individual sensors are available as standard and Ex protection type sensors. The pre-alarm (PA) is self-resetting; depending on the program the main alarm (MA) is also self-resetting or has to be reset manually. Specifications A.
