-40℃～+120℃ Industrial-grade Smoke Alarm /Lithium Battery AgingSmoke 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 structured infrared photoelectric sensor, a reliable MCU, and is manufactured using SMT surface mount technology. It features high sensitivity, reliability, low power consumption, beautiful appearance, durability, and ease of use.
Precautions:
II. Working Principle
The detector uses a specially structured photoelectric sensor combined with a reliable MCU to effectively detect smoke generated during the initial smoldering stage of a fire or after its occurrence. When smoke enters the detector, it causes light scattering from the light source. The light-receiving element senses the light intensity, and the received light intensity has a linear relationship with the smoke concentration. The detector continuously collects, analyzes, and judges on-site parameters. When it confirms that the light intensity of the on-site data reaches the preset threshold, it activates the relay output. When the smoke in the environment returns to normal, the detector automatically resumes normal operation. Self-test: Under normal conditions, press the self-test button, and the detector will perform an internal function test and activate the relay output. Note: When the detector alarms, the output relay provides a dry contact with a contact capacity of 1A/24VDC.
III. Technical Characteristics
