JTY-GD-HA621-RS485 Charging Pile Smoke Alarm/New Energy Vertical WarehouseSmoke Sensor/Battery Swap Station Smoke Detector
The JTY-GD-HA621-RS485 photoelectric smoke fire detector (hereinafter referred to as the detector) is suitable for fire pre-alarming in civil and industrial places such as shopping malls, hotels, stores, warehouses, and motor rooms. The detector features high sensitivity, stable and reliable performance, low power consumption, beautiful and durable design, and easy operation, and can be used in conjunction with security systems.
I. Performance
Alarm sound: ≥80dB
Power supply: DC9V~DC28V
Current: Quiescent current ≤200uA
Alarm current ≤45mA
Operating temperature: -10℃~+50℃
Relative humidity: ≤95%RH (40℃±2℃)
Smoke sensitivity: 1.06±0.26% FT
Compliant standard: GB4715-2005
Communication interface: RS-485
Communication protocol: Modbus-RTU
II. Functions
Self-test: Press the test button, the detector's LED stays on continuously and emits an alarm sound at the same time (Note: The self-test only checks the internal functions of the detector; smoke spraying can also be used for testing).
Operation: Under normal circumstances, the indicator light of the detector flashes approximately every 6 seconds. The detector automatically detects the smoke concentration in the surrounding environment and performs automatic sensitivity compensation according to the usage environment. When the smoke concentration approaches the alarm value, the detector accelerates the intelligent calculation of the smoke concentration change trend, and the alarm indicator light starts flashing. If the calculation result reaches or exceeds the alarm value, the detector enters the alarm state. When the smoke concentration in the surrounding environment drops below the alarm value, the detector automatically returns to the normal working state.
RS-485 communication: Adopts a standard RS-485 communication interface, and the communication baud rate can be selected as: 2400bps, 4800bps, 9600bps, 19200bps, with a default of 4800bps.
Modbus-RTU protocol: The alarm status register address is 03, read via function code 03, with status "0" or "1". For normally open mode ("1" means normal, "0" means alarm), for normally closed mode ("0" means normal, "1" means alarm).
