Gas Detector electrochemical
6as Detector Unit available with either 1 or 2 electrochemical sensors, suitable for indoor and outdoor user. The GSE 410 and GSE 420 are BUS Units that are designed to detect toxic or combustible gases as well as oxygen. They offer the highest reliability and maximum performance in a compact housing, and offer Factory calibration to industry standard measuring ranges. They are idéal for use in underground garages and multi-storey car parks, as well as in ail industrial areas.
•Can be used with ail SCENTY® BUS gas warning Systems
•Available with one or two Sensor Units
•Monitors the air for toxic gas concentrations
•Particularly suitable for monitoring underground garages
•Low cross-sensitivity to other gases
The gas sensor GSE 410/420 can be used as single or double sensor (combination gas sensor).
Our GSE 410 version is designed to accept only one Sensor Unit, but the GSE 420 is designed to accept two Sensor Units.The GSE 420 version was specifically designed for use in underground garages and parking areas.
We recommend a stable 24 V DC power supply to operate the gas sensors GSE 410/420. The allowed voltage range is 18 to 36 V DC.The sensor may be connected using a shielded cable with three twisted pairs, i.e.JY(St)Y 3 x 2 x 0.8 mm.
Make sure one pair (in parallel) is used as +24 V conductors, another pair (in parallel) as the GND/0 V conductors and the third pair as data pair conductors. Shielding and a twisted pair for the data Unes is mandatory.
We recommend twisting the supplementary earth wire and the yellow wire at the control unit and connecting those two to terminal 4 (PE).
