Product Overview

JTY-GM-HA261-WS-RS485 is a photoelectric smoke temperature and humidity detector, As a 3-in-1 sensor, it can monitor environmental temperature, humidity, and smoke. The smoke detection adopts a scientific maze structure and photoelectric signal processing technology, which has functions such as dust prevention, insect prevention, and resistance to external light interference, ensuring the stability of the product from the design. This product has a good response to visible smoke generated by slow smoldering or bright burning. Suitable for smoke monitoring in environments such as cabinets, substations, and energy storage. When the environmental smoke concentration reaches the set alarm concentration threshold, the product immediately emits an audible and visual alarm, and the relay outputs a switch signal. If the environmental smoke concentration is lower than the alarm concentration threshold, the product will stop alarming. The temperature and humidity data are sent to the user's upper computer through the RS485 interface. After the user obtains the sensor data, they can proceed with secondary development.

Instructions for Use

(1) Indicator light status standby state: The red light flashes once every 8 seconds;

Alarm status: The red light remains on when there is a smoke alarm;

(2) Buzzer status: When in smoke alarm or test state, the sensor emits

Make a "beep beep" alarm sound;

(3) Test button: Short press the test button to test the sensor's sound and light alarm function,

The red indicator light flashes rapidly, and the buzzer emits a "beep beep" alarm

Voice; Press and hold the test button for 8 seconds to restore the sensor to its factory settings,

At the same time, the buzzer beeps continuously.

(4) Alarm status: When the environmental smoke concentration reaches the set alarm concentration threshold

When the value is reached, the red indicator light of the sensor stays on and the buzzer emits a beep sound

Drip "alarm sound; When the environmental smoke concentration is below the alarm concentration threshold, transmit

The sensor returns to normal monitoring state.

Precautions

According to GB/T15464-1995 General Technical Specifications for Instrument Packaging

Transport and storage shall be carried out in accordance with the regulations of the document.

There should be no obstructions within 0.5m around the detector.

The horizontal distance from the detector to the air conditioning vent should not be less than 1.5m.

4. During transportation and storage, the original packaging and sealing of the production factory must be maintained

Ensure that the product is not subjected to severe impact.

5. The detector should be installed horizontally, and if it must be installed at a tilt angle, the tilt angle should not exceed 45 degrees.

6. It is recommended to conduct a simulated fire alarm test every six months to test whether the detector is working properly.
