Description :
The JTY-GD-HA621-RS485 photoelectric smoke fire detector (hereinafter referred to as the detector) is suitable for fire prediction and alarm in civilian and industrial places such as shopping malls, hotels, shops, warehouses, and motor rooms. The detector has the characteristics of high sensitivity, stability and reliability, low power consumption, beauty and durability, and easy use, and can be used in conjunction with security systems.
One Performance:
Alarm sound: ≥ 80dB
Power supply: DC9V~DC28V
Current: Static current ≤ 200uA
Alarm current ≤ 45mA
Working temperature: -10 ℃~+50 ℃
Relative humidity: ≤ 95% RH (40 ℃± 2 ℃)
Smoke sensitivity: 1.06 ±. 26% FT
Compliant with standard: GB4715-2005
Communication interface: RS-485
Communication protocol: Modbus RTU
II Function:
Self check: Press the detection button, the detector LED will remain on, and an alarm sound will be emitted (note: self check only checks the internal functions of the detector itself, and there is no relay signal output during self check).
Work: Under normal circumstances, the detector's indicator light will flash approximately every 6 seconds. The detector automatically detects the smoke concentration in the surrounding environment and compensates for sensitivity based on the usage environment conditions. When the smoke concentration approaches the alarm value, the detector accelerates the intelligent calculation of the smoke concentration trend, and the alarm indicator light starts to flash. If the calculation result reaches or exceeds the alarm value, the detector will start to sound and light an alarm. When the smoke concentration in the surrounding environment drops below the alarm value, the detector automatically resumes normal operation.
RS-485 communication: Using standard RS-485 communication interface, the communication baud rate can be selected as 2400bps, 4800bps, 9600bps, 19200bps, and the default is 4800bps.
Modbus RTU protocol: The alarm status register address is 03, which is read using function 03. The status is "0" or "1", normally open ("1" is normal, "0" is alarm), and normally closed ("0" is normal, "1" is alarm).
