JTY-GD-HA621-RS485 Charging Pile Smoke Alarm/New Energy Vertical WarehouseSmoke Sensor/Swap Station Smoke Detector

The JTY-GD-HA621-RS485 photoelectric smoke fire detector (hereinafter referred to as the detector) is suitable for pre-alarming fires in commercial and industrial places such as shopping malls, hotels, shops, warehouses, and motor rooms. The detector features high sensitivity, stability and reliability, low power consumption, aesthetic durability, and ease of use, and can be used in conjunction with security systems.

I. Performance

Alarm sound: ≥80dB

Power supply: DC9V～DC28V

Current: Standby current ≤200uA

Alarm current ≤45mA

Operating temperature: -10℃～+50℃

Relative humidity: ≤95%RH (40℃±2℃)

Smoke sensitivity: 1.06±.26%ＦＴ.

Compliance 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, and an alarm sound is emitted (Note: The self-test only checks the internal functions of the detector itself; smoke spray can also be used for testing).

Operation: Under normal conditions, the detector's indicator light flashes approximately every 6 seconds. The detector automatically monitors the surrounding smoke concentration and performs automatic sensitivity compensation based on environmental conditions. When the smoke concentration approaches the alarm threshold, the detector accelerates intelligent calculation of the smoke concentration trend, and the alarm indicator begins to flash. If the calculation result reaches or exceeds the alarm threshold, the detector enters the alarm state. When the surrounding smoke concentration drops below the alarm threshold, the detector automatically returns to normal operation.

RS-485 communication: Uses a standard RS-485 communication interface, with selectable baud rates: 2400bps, 4800bps, 9600bps, 19200bps; default is 4800bps.

Modbus-RTU protocol: The alarm status register address is 03, read using function code 03. Status is "0" or "1": normally open ("1" for normal, "0" for alarm), normally closed ("0" for normal, "1" for alarm).
