Answer:
The GST DI-9101E measures 100 mm in diameter by 54.5 mm in height (including base) and weighs approximately 110 g. It operates on a 24V DC loop (16V to 28V DC allowable) with a standby current of ≤0.8 mA, an alarm current of ≤1.8 mA (≤3.8 mA with remote indicator), and an operating temperature range of -10°C to 50°C.
The GST DI-9101E Intelligent Combination Heat Photoelectric Smoke Detector, supplied with the DB-01 standard mounting base, operates as a loop-powered addressable device designed for indoor commercial and industrial fire alarm systems. Key engineering and operational parameters include:
- Operating Voltage: Nominal 24V DC (operating loop range: 16V DC to 28V DC).
- Current Consumption: Standby current ≤0.8 mA; alarm current ≤1.8 mA without remote indicator, ≤3.8 mA when driving an external remote indicator.
- Remote Indicator Output: Polarized output with a built-in 10 kΩ series resistor delivering a 2 mA output current; flashes in alarm and remains unlit during normal standby.
- Heat Detection Rating: Class A2R with a rated action temperature of 62°C, combining fixed-temperature and rate-of-rise thermal monitoring.
- Smoke Sensitivity: Two field-programmable levels; Level 1 spans 0.084 dB/m to 0.162 dB/m (EN 54-7 compliant), and Level 2 spans 0.101 dB/m to 0.220 dB/m.
- Coverage: 7.5-meter operating radius under flat ceilings up to 25 meters in height for the optical smoke sensor.
- Dimensions & Weight: 100 mm diameter, 54.5 mm height (including DB-01 base); weight approximately 110 g.
- Enclosure & Environment: Fire-resistant ABS plastic construction rated IP2X (indoor use only); operating temperature range of -10°C to 50°C with relative humidity up to 95% (non-condensing).
