Answer:
The GST I-9104 operates on a 24VDC loop (12VDC to 28VDC range) with a standby current of ≤2mA and alarm current of ≤2.5mA. It has an optical spectral response range of 185 nm to 260 nm, measures 103 mm in diameter by 53.5 mm in height with base (100 mm × 41 mm without base), and weighs approximately 110 g.
The GST I-9104 Intelligent Ultraviolet Flame Detector is built to the following technical and physical parameters:
- Operating Voltage: Nominal Loop 24VDC (allowable range: 12VDC to 28VDC).
- Operating Current: Standby current ≤2mA; action/alarm current ≤2.5mA.
- Spectral Response Range: 185 nm to 260 nm (ultraviolet spectrum).
- Detection Distances: Level I: 25 m; Level II: 17 m; Level III: 12 m (verified against a 2000 g industrial ethanol fire in a 33 cm × 33 cm × 5 cm container).
- Dimensions: 103 mm diameter × 53.5 mm height (with base); 100 mm diameter × 41 mm height (detector body alone).
- Enclosure & Weight: ABS plastic finished in white (RAL 9016), rated IP21, weighing approximately 110 g.
- Operating Temperature & Humidity: -20°C to +55°C; relative humidity ≤95% non-condensing.
- Status Indication: Red LED that flashes during periodic panel polling and illuminates steadily upon fire alarm condition.
