JTY-ZOM-HA211-RS485Network-Type Heat-Sensing Fire Detector / Point-Type Heat-Sensing Fire Detector / Switch (Dry Contact)
I. Overview:
The JTY-ZOM-HA211-RS485 network-type heat-sensing fire detector (hereinafter referred to as "the detector") is suitable for fire pre-alarming in civil and industrial sites such as substations, computer centers, stores, warehouses, and motor rooms. The detector features high sensitivity, stability and reliability, low power consumption, elegant 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℃) Alarm temperature level: A1R (lower limit 54℃, upper limit 65℃, fixed temperature 57℃) 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, and no relay signal is output during self-test.)
Operation: Under normal conditions, the indicator light of the detector flashes approximately every 6 seconds. The detector automatically detects the smoke concentration in the surrounding environment and automatically compensates for sensitivity according to the usage environment. 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 flashing. If the calculation result reaches or exceeds the alarm value, the detector starts audible and visual alarm. When the smoke concentration in the surrounding environment drops below the alarm value, the detector automatically returns to normal working status.
RS-485 Communication: Adopts a standard RS-485 communication interface, and the communication baud rate can be selected as: 2400bps, 4800bps, 9600bps, 19200bps, with the default being 4800bps. Modbus-RTU Protocol: The alarm status register address is 03, read via function code 03. Status is "0" or "1": normally open ("1" is normal, "0" is alarm), normally closed ("0" is normal, "1" is alarm).
