Answer:
The GST I-9105R operates across an optical pathway length of 8 to 100 meters, covering a maximum monitoring area of 1,400 m² with a 14-meter beam width. The transceiver unit measures 206 mm × 95 mm × 95 mm, weighs approximately 1.3 kg, and carries an IP20* ingress protection rating.
The GST I-9105R is an intelligent reflective infrared optical beam smoke detector engineered for open spaces with high ceilings. Key physical, optical, and environmental specifications include:
- Optical Pathway Length: 8 m to 100 m total separation between transceiver and reflector.
- Coverage Geometry: Maximum monitoring area of 1,400 m² with a lateral detection width of up to 14 m.
- Enclosure Dimensions: 206 mm (L) × 95 mm (W) × 95 mm (H).
- Weight: Approximately 1.3 kg.
- Operating Voltage: 24VDC (±10%) auxiliary supply; 24VDC (15V to 28V) addressable loop voltage.
- Current Consumption: 12mA standby current; 22mA alarm current.
- Angular Adjustment & Tolerance: Optical alignment adjustment from -6° to +6° with a maximum angular misalignment tolerance of ±0.5°.
- Operating Environment: -10°C to +50°C operating temperature range; IP20* ingress protection rating.
- System Cabling: Requires 1 pair for 24VDC auxiliary power (terminals D1/D2) and 1 pair for loop communication (terminals Z1/Z2) using fire-rated cable with a minimum cross-section of 1.0 mm².
