Answer:
The GST DC-9102(IS) measures 100 mm in diameter by 54.5 mm in height (including base) and weighs approximately 110 g, with base mounting hole spacing from 45 mm to 75 mm. It operates at 24 VDC (16 VDC to 28 VDC) with a standby current of ≤60 µA and an alarm current of ≤30 mA.
The GST DC-9102(IS) conventional intrinsically safe photoelectric smoke detector has an enclosure constructed from ABS plastic with an outer diameter of 100 mm and an overall height of 54.5 mm when fitted to its mounting base. The complete assembly weighs approximately 110 g and accommodates base mounting hole pitches between 45 mm and 75 mm.
Operating power specifications are:
- Operating Voltage: 24 VDC nominal (operational range: 16 VDC to 28 VDC)
- Standby Current: ≤60 μA
- Alarm Current: ≤30 mA
- Alarm Reset: Instantaneous power interruption of 5 seconds minimum with loop voltage reduced to 2.5 VDC maximum
- Environmental Limits: Operating temperature range of -10°C to +55°C and relative humidity ≤95% (non-condensing)
