-40℃ to +120℃ Industrial Grade Smoke Alarm/Lithium Battery Aging Smoke Sensor/Aging Cabinet Smoke Detector

JTY-GD-HA521 Industrial Grade Photoelectric Smoke Fire Detector

I. Product Overview:

The networked photoelectric smoke fire detector (hereinafter referred to as the detector) adopts a specially designed infrared photoelectric sensor, a highly reliable MCU, and SMT processing technology. It features high sensitivity, stability and reliability, low power consumption, aesthetic durability, and ease of use.

Precautions:

1、 Not suitable for environments where smoke normally lingers.

2、 Not suitable for environments with high levels of dust, water mist, steam, oil mist pollution, or corrosive gases.

3、 Not suitable for environments with relative humidity greater than 97% or ventilation speeds exceeding 5m/s.

4、 Please read the installation and user manual before installing and using the product.

II. Working Principle

The detector uses a specially structured photoelectric sensor combined with a highly reliable MCU to effectively detect smoke generated during the initial smoldering stage of a fire or after ignition. When smoke enters the detector, it scatters the light source, and the light-receiving component senses the light intensity. There is a certain linear relationship between the received light intensity and smoke concentration. The detector continuously collects, analyzes, and judges on-site parameters. When the light intensity of the on-site data reaches the predetermined threshold, it activates the relay output. When the smoke in the environment returns to normal levels, the detector automatically resumes normal operation. Self-test: Under normal conditions, press the self-test button to perform an internal functional test of the detector, and the relay will output. Note: When the detector alarms, the output relay has a passive contact with a contact capacity of 1A/24VDC.
