Page 3: General Warning
1. GENERAL WARNING Symbol warns the user about the presence of non-insulated "dangerous voltage" inside the product area, which may cause electric shock. Symbol warns the user about the presence of important operating and maintenance (assistance) instructions found in the documentation attached to the device. ... -
Page 4: Product Disposal Wee
1.1 PRODUCT DISPOSAL WEE With reference to Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 and to the relative national legislation, please note that: There lies the obligation not to dispose of electrical and electronic waste as municipal waste but to separate the waste. -
Page 5: General Information
2. GENERAL INFORMATION The GD product range is a state-of-the-art fixed gas detector which can detect a wide range of different gases. This kind of gas sensors are available in two different configurations in relation to the type of sensing element: ... -
Page 6: Typical Use
2.1 TYPICAL USE The GDS and GDI Gas Sensors can be used in new buildings/areas that require continuous monitoring with high tech gas sensor transmitters or to add gas detection solutions to an existing system. It’s possible to use the Gas Detectors in different modes: ... -
Page 7: Placement
3.2 PLACEMENT Sensors must be located within the appropriate wire lengths from the central control unit (if used). In all cases the sensor supplied is designed for maximum sensitivity to a particular gas. However, in certain circumstances false alarms may be caused by the occasional presence of sufficiently high concentrations of other gaseous impurities. -
Page 8: Positioning Height
3.2.1.1 POSITIONING HEIGHT For heavier-than-air gases such as halocarbon and hydrocarbon refrigerants such as R404A, propane, and butane sensors should be located near ground level. With similar density or miscible gases (e.g. CO ), sensors should be mounted about head high (about 1.5 m). -
Page 9: Air Conditioning (Direct System Vrf/Vrv)
3.2.4 AIR CONDITIONING (Direct System VRF/VRV) For compliance with EN378, at least one detector shall be installed in each occupied space being considered and the location of detectors shall be chosen in relation to the refrigerant and they shall be located where the refrigerant from the leak will collect. In this case refrigerants are heavier than air and detectors should have their sensors mounted low, e.g., at less than bed height in the case of an hotel or other similar Category Class A spaces. -

4.1 WIRING AND SETTINGS ITEMS DESCRIPTION To open the standard sensor enclosure, turn the cable clamp 1/2 turn counter-clockwise to loosen the internal gland nut, depress the clip on top of the enclosure and open. Enclosure Access Reverse to close. (Note: For the IP66 enclosure, use the four bolts on the front cover.) 12-24V AC/DC, connect at positions 0V and +V at connector... -
Page 12: Configuration
On power up, the semiconductors output over the + max scale (i.e., > 5V), move towards zero as they stabilize. If sensors have been in long-term storage or the detectors have been turned off for a long period, stabilization is much slower. However, within 1-2 hours sensors should have dropped below the alarm level and be operational. -
Page 13: Calibration
GDS (Semiconductor) GDI (Infrared) 4.5 CALIBRATION For proper use and to provide a correct signaling sensors must be tested. The frequency and nature of testing or calibration may be determined by local regulation or standards. EN378 and the F-GAS Regulation require an annual check in accordance with the manufacturer’s recommendation. -
Page 14: Housing Dimensions
The GDS or GDI is calibrated at the factory. After installation, a zero adjustment maybe required due to differences in environmental conditions. If the GDS or GDI is exposed to a large leak it should be tested to ensure correct functionality by electrically resetting the zero setting and carrying out a bump test. -

Dimensions for the GD Gas Sensors with IP66 housing: 5. TROUBLESHOOTING SYMPTOM POSSIBLE CAUSE(S) Check power supply. Check wiring. Green and Red LED off GDS or GDI was possibly damaged in transit. Check by installing another GDS or GDI to confirm the fault. Sensor may be disconnected from printed circuit board. -
