Answer:
The GST I-9403 operates on 24VDC (20V to 28V loop and external supply), generates up to 86 dB at 1 m (Tone 14, normal mode), and measures 110 mm in diameter by 95.9 mm in height with the standard shallow base at an approximate weight of 327.2 g and IP33 rating.
The GST I-9403 Intelligent Sounder Strobe (Product No. 10106295) is an addressable audible and visual warning device constructed from ABS plastic. Key technical specifications include:
- Operating Voltage: 24VDC (voltage tolerance 20VDC to 28VDC) across both addressable loop and external auxiliary power lines.
- Dimensions & Weight: 110 mm diameter × 95.9 mm height (with shallow base); total weight is approximately 327.2 g. Mounting hole pitch supports spacing between 55 mm and 80 mm / 83 mm.
- Acoustic Output: Maximum sound level measured at 1 m (A-weighted, external 24VDC, normal mode) achieves 86 dB on Tone 14, 84 dB on Tone 16, and 76 dB on the pre-alarm tone.
- Current Consumption (Power-Saving Mode): Loop-powered standby monitor current ≤2 mA, start current ≤9 mA. External 24V powered loop monitor current ≤1 mA, loop start current ≤2 mA, power monitor current ≤1 mA, and power start current ≤9 mA.
- Current Consumption (Normal Mode): Loop-powered standby monitor current ≤2 mA, start current ≤35 mA. External 24V powered loop monitor current ≤1 mA, loop start current ≤2 mA, power monitor current ≤1 mA, and power start current ≤35 mA.
- Environmental Ratings: Ingress protection rating IP33; operational temperature range of -10°C to +50°C; relative humidity resistance up to 95% (non-condensing).
